Recent versions

Over the last weeks, we've received several reports about bugs that slithered in the latest release. They turned out to be both moderately important and relatively easy to fix, so we decided to release a new update off-schedule.

[Fixed] "Reinstall certificate" feature does not work in Firefox #2013

While not being the most important feature, the automatic certificate reinstall is more relevant for Firefox-based browsers than for any other ones. This fix eliminates the need to do it manually.

Networking

  • [Fixed] Connect to 66.ru failed: ERR_CONNECTION_CLOSED #1991
  • [Fixed] Can't send pictures in desktop Viber app #1990

Other

  • [Fixed] Fix the translation for the 'Get Premium' tile #1999
  • [Fixed] Baofeng video software compatibility issue #1993
  • [Fixed] Several userscripts compatibility issues #1986

Hello! The changelog this time is truly gigantic. Every time we thought we were going to release the current version, there was always something we felt was essential to fix, add or improve. How did it turn out?

Let's start with UI changes. Both Filtering log and Filter editor have been seriously redesigned. We need to say a big 'thank you' to everyone who has expressed his or her opinion because few changes depend as heavily on users' feedback as these.

[Changed] Filtering log rework #96

We know for certain that quite a few of our users are actively using Filtering log — both for creating new custom rules and generally knowing what's going on. So why not help them a bit? It has undergone a major renovation. New Filtering log overlaps with Filter editor a great bit, for example, you can create new rules and unblock blocked requests right therefrom.

There are more details to see about each request, too. The request details dialog window is very reminiscent of the Developer tools in Chrome browser. All in all, the new Filtering log is much more than a simple list of which requests are blocked and which are not.

[Changed] Filter editor rework #1293

Filter editor has also changed for the best. The addition of an 'Edit mode' allows replacing the data grid with a text area. This lets you copy/paste/delete many rules at once without having to bother with export/import.

Basic hotkeys are now available, which will speed up the process of working with the filter editor. There are many other quality of life changes, especially to the UI, which will draw your attention as soon as you launch the new version.

[Added] Integration with Windows 10 notifications center #1554

Many Windows 10 users find the Notification center to be helpful when it comes to tracking the activity of their apps. We have finally decided to take advantage of it and integrated AdGuard with the center. AdGuard has a surprisingly decent amount of various notifications. Just to name a few: notifications related to the license/trial period, automatic filter activations, new rules in User filter, Safebrowsing triggers, update checks results, etc. If you use Windows 10, you'll be able to find them all in one place now, thus making it much easier to keep up with what's going on with AdGuard.

[Changed] Network settings moved to a separate settings tab #1404

This one is rather straightforward. Previously, all network settings were crowding inside the 'General settings' tab making it harder to scroll up in down, searching for the one setting you need. Adding a separate first-level tab makes it easier to navigate through the app.

Assistant and other extensions

While not being an integral part of AdGuard for Windows, some extensions (or *userscripts*) have grown over time to become strongly associated with it. And we showed them some love!

AdGuard Assistant

A lot has been done in terms of improving AdGuard Assistant, and a lot more is planned for the future, so we decided to allocate it a separate, own GitHub repository: https://github.com/AdguardTeam/AdguardAssistant/

By the way, you may notice that the 'Report website' button now leads to a whole new page. Basically, what you see is a web reporting tool that allows you to easily send us a report on anything from a missed ad to a false positive. More about this later.

What else is done already? The biggest change is the ability to drag the Assistant icon across the page and place it wherever you see fit. Moreover, AdGuard will memorize the position of the Assistant icon for each website separately, so you can really customize it according to your taste and preferences.

The Assistant interface overall has become smaller but retained full functionality compared to earlier versions. There is even one new feature: a switch for toggling the filtering on the website on and off. Previously, the Assistant wasn't shown on websites with disabled filtering, and you had to go to User filter to enable it back.

Oh, and we could use your help with translating the new Assistant. Did you know that anyone can volunteer as a translator? If you feel confident, head right here and find your native language. Don't forget to read through the translator's memo.

AdGuard PopupBlocker

[Added] AdGuard PopupBlocker extension v2.1 #1883

For quite a while now, AdGuard works as a userscript manager — you can install any script via AdGuard to use it in any browser. PopupBlocker has always been one of the 'native' userscripts that are installed by default, alongside AdGuard Assistant. Its purpose is clear — to block any unwanted pop-ups.

Previous version (v1.0) was functional but very little beyond that. We have completely redesigned the PopupBlocker. It now has advanced pop-up detection, compared to its predecessor and its alternatives, restores the initial click behavior and is invisible to other scripts. All in all, new PopupBlocker is a solid addition to your online protection suite.

By the way, it is available as a standalone script that can be used on its own with any other userscript manager. To find more information about PopupBlocker, visit its GitHub repository.

Reports web app

[Added] Integration with Reports Web App #1964

When it comes to keeping our filter lists updated, we owe our users a big one. Thanks to their timely reports of missed ads, false positives etc., AdGuard filters are always up-to-date. We want to make the process of reporting a website easy for users and informative for filter developers, that’s why we decided to integrate AdGuard for Windows with a special web reporting tool.

When you see any problem like missed ad or annoyance, click on the Assistant icon and choose “Report this website”. You will be taken to a new page and asked to fill in some information about your AdGuard settings and the nature of the problem. Good thing is that AdGuard pre-fills most of the fields automatically, so most of the job is already done for you :)

We hope this change will strengthen the feedback from our users and allow AdGuard filters to stay at the cutting edge of ad blocking technology.

Userscripts handling

[Changed] The way AdGuard handles userscripts #1714

A lot of effort has been put into improving (better to say, rethinking) the way AdGuard works with userscripts. This actually has two different aspects:

First, from now on, the communication between AdGuard and Assistant is based on WebSocket, which results in better performance. This is also perfectly applicable to AdGuard Browser extension, when it is working in the integration mode with AdGuard for Windows.

Second, we have taken a whole complex of measures that allow for any external userscripts that you install via AdGuard to show higher speed and execution stability.

Other important changes

[Added] Settings export/import #1405

A lot of users were asking for this, and finally we deliver. Now you can save your settings configuration into a file and then use it to set up AdGuard on another machine exactly how you prefer. Another implication of this is to quickly switch between different settings profiles without having to feverishly click through a dozen of tabs and checkboxes.

[Improved] A complete "Exit AdGuard" functionality was added #1509

Now users have a choice between closing AdGuard as they usually do, and closing it completely. That means closing the Windows service as well as UI, and when UI is getting started again, the service will start as well (you may be asked for the admin privileges, though).

[Added] An option to create custom filters not backed with a file #1669

In addition to the usual option of adding any list by URL or loading it from a local file, you can now create independent new filters from scratch. It is possible to create several such filters, give each of them their own name and fill with any rules. As a result, you can create a set of specified filters which can be separately enabled, disabled and edited.

This update might not be the biggest one, in a sense it doesn't feature any revolutionary additions or the immense number of changes. But it's surely a unique one, and it's because it is by far the most influenced by the user feedback. We sincerely thank everyone who has helped us!

It is super important for two big reasons, both concern networking/compatibility: we have *finally* fixed the compatibility issue with KIS/ESET and, also, we've fixed a certificate issue in modern Chrome versions (59+). Details below.

[Fixed] Compatibility with KIS/ESET #1565

Adguard used to have compatibility issues with such antivirus software like Kaspersky and ESET. Users had to seek for compromises: disabling SSL scanning in antivirus, disabling WFP driver or even HTTPS filtering in Adguard. The core of the problem was the WFP network driver incompatibility, and we had had plans to develop a new driver for what now seems like an eternity.

We'd already claimed to have this fixed in the previous releases, but things turned out to be more complicated. We've come through countless iterations, test builds, and driver updates, and now we are confident enough to say that this time the problem is fixed for real. No more BSODs and other funny stuff when you run Adguard alongside with KIS or ESET.

And again, we can't thank enough everyone who was willing to cope with raw test builds and provided invaluable feedback in order to help us make things right. Just look at the task - it is blowing up with comments. We are happy to have such users, you are awesome.

[Fixed] Compatibility with Chrome 59+ #1597

With big news which WFP driver compatibility fix is it could be easy to neglect other changes. And that would be so wrong! This fix, in particular, is of utmost importance. It ensures Adguard will run without problems on modern (v59+) Chrome versions. Otherwise, there would be troubles with Adguard certificate validation.

Other

  • [Changed] The search criteria in the filtering log were extended #1513
  • [Changed] Connections are not allowed if DH1024 is in use #1616
  • [Changed] The default HTTPS exclusions list has been updated #1618
  • [Fixed] Adguard Service keeps downloading data after closing the browser #1599
  • [Fixed] An error encountered when adding a filter by URL #1583

UPD: hotfix update 6.1.314 brings a fix for the bug #1569, messing with filtering when HTTPS filtering is disabled.

It was quite a while since the last Adguard for Windows release. And there are other reasons for that apart from the Christmas/New Year holidays: we'd been extensively testing the new network driver before, finally, we felt ready to include it in the new release version. But what is there for me in this network driver, you might ask? Well, it fixes an old compatibility issue with several antivirus programs. For sure, there are other fixes and changes as well, and you will find the whole list below.

You can also find all relevant information about this release (and discuss it) in our blog.

Networking

[Improved] WFP driver was updated to fix compatibility issues with KIS and ESET #1497

Previously, it was not unusual at all that Adguard would have compatibility issues with some antiviruses, and KIS and ESET being the most common ones. The workarounds existed but were far from ideal - you had had to sacrifice some parts of functionality on either Adguard or antivirus side. With updated WFP driver these conflicts will be no more, allowing users to run Adguard alongside with KIS and ESET.

[Improved] The way we respond to HTTP protocol violation #1452

It would take too long to explain technical nuances, but effectively this fixes the problem some users might have come across before: when you try to open a page and it is downloaded as a file instead.

  • [Fixed] $popup rule bug #1504
  • [Fixed] QUIC protocol issue when KIS is installed #1482
  • [Fixed] HideUserSearch option breaks the 'maximize' button graphics #1536
  • [Fixed] 'Disable Fast Open' setting doesn't work in latest Insider Preview builds #1487
  • [Fixed] Several issues in Firefox with the default value of 'Hide you user-agent' setting #1493

Ad Blocking

  • [Added] $network basic rules modifier to solve the issue with loading ads through WebRTC #1297

  • [Fixed] $replace rules aren't applied to .m3u8 files content #1428
  • [Fixed] Regular expressions with $ aren't processed properly #1475

UI

[Changed] WOT extension is now disabled by default #1364

Recently, an article was posted in one of the popular technology blogs, claiming that Web of Trust is selling its users' browser history to third-parties. WoT extension is preinstalled in Adguard for Windows, and although it was developed by us and is not sending any of your data to WoT, we can not leave this without a reponse. For this reason we make WoT extension disabled by default in Adguard for Windows. You can read our official stance regarding these news in our blog.

  • [Changed] You can now completely remove WoT extension #1364

Install/Update

Many other minor fixes and changes. The full list can be found in descriptions to prior beta versions in our repository on GitHub.

Briefly about new Adguard for Windows version: Stealth Mode got new useful options, userscripts work better now, ad blocking became more advanced and our network drivers - more stable. All the details are below.

Stealth Mode

[Added] "Self destructing cookies" option in Stealth Mode #678

Previously Stealth Mode module provided only the option to completely block third-party cookies. Now you will not only have an ability to differ first- and third-party cookies, but also the ability to set the exact time which cookies will be kept alive for. Important note: you can still block cookies alltogether, just set the keep-alive time to '0'.

[Added] Added an option to block "Browser location API" #139

[Added] Added an option to block "Browser notifications API" #1121

Normally browsers may detect your location and use this information to prioritize specific search results or make other various suggestions based on it. With browser location API blocked this will be impossible.

Blocking browser notifications API feature works somewhat similar, but rather prevents browser from showing things like news or social media frames that pop-up in the corner of your browser.

Userscripts

[Improved] Content injection algorithm #1099

We completely redesigned content injection algorithm. First and foremost, this should solve issues with scripts that start when the page opens, resolve some of the known conflicts (AdsBypasser, YouTube+), and also optimize usage of scripts and ad blocker styles. Overall, a technical, but very important change.

[Added] Userscripts handling #1172

We adopted a new way of handling user.js (userscript) files. Now Adguard will automatically detect when user.js file was processed. If it is a valid userscript, Adguard will open a dialog window, offering user to install it. Of course, this setting will be optional and possible to turn off through settings.

UI

[Added] Hebrew localization, Dutch localization #1076, #1063

We continue to make Adguard more easily accessible for users all over the world. This time we add two more new localizations and fix some mistakes in already existing ones.

Networking

[Improved] Network SDK was updated #1179

In reality, this implies many various fixes that concern our network drivers. It would be hard to list them all here, and most of them are rather technical anyway. For example, the WFP driver - Windows Defender compatibility issue was addressed.

Ad Blocking

[Added] Support for extended selectors #1225

This is a technical term, but what hides behind it? With extended selectors support, we can much more easily create some rules that were very, very hard to create earlier. Notably, this concerns rules required to block such things as 'Sponsored posts' on Facebook.

[Added] Extended CSS support https://github.com/AdguardTeam/ExtendedCss

This is a very important addition in terms of future (and present) possibilities that it opens for ad blocking. Extended CSS is a module for applying CSS styles with extended selection properties. Basically, it means that we will be able to select and, therefore, block some elements that we would not be able to block otherwise. Currently we support following pseudo-classes: -ext-has (:has), -ext-contains (:contains), [-ext-matches-css (:matches-css).

Other

Dozens of minor fixes and improvements.

A hotfix after last weeks release. Previously there turned out to be several problems, including router page loading problem and other. These bugs are fixed with this version.

  • [Fixed] Indefinite loading of router page #1042
  • [Fixed] Rare problem when Adguard crashes after clicking on tray menu icon #1045
  • [Fixed] Adguard will not crash any more if you switch tabs while have active search on 'Settings' screen #1043
  • [Fixed] Adguard now detects HTML correctly for all websites if there is an xml declaration at the document start #1011

Good news, everyone! We haven't seen any new bugs since the latest beta version, and it means nothing else but the new stable release is arriving. During the last couple of months that had passed since the 6.0 release we were able to track quite a lot of bugs and defects, which were crucial to fix. So we concentrated on them for a while. Finally, everything seems to be fixed and we are ready to turn on the autoupdate for all our users who still use Adgguard 5.10. We were looking forward to this moment! Even if you were already using Adguard 6 and you are not as excited by these news, you should be. This release means we can finally put all our efforts into implementing cool new features you might have or have not seen in our [roadmap]. In case you missed last beta releases and respective release notes, you can catch up and read about all the fixes and additions below. Most important of them, as usual, are described in detail.

UI changes

  • [Changed] Adguard uses native-style tray menu now #1006
  • [Changed] Adguard window is now opened with a single click on tray menu #1030
  • [Fixed] 'About' window content is not flickering anymore #954
  • [Fixed] Empty strings are now removed when importing user filter #973
  • [Fixed] Error previously encountered while installing a userstyle #934
  • [Improved] Proxy name validator now recognizes domain names and not only IP addresses #931

Ad Blocker

  • [Improved] Added $stealth modifier that disables Stealth Mode for the specified website #339 As we already mentioned in our blog, separate whitelist for Stealth Mode is on our roadmap. It is a much needed feature for anyone who actively uses Stealth Mode. We are not quite there yet, but we made a big step in the right direction by implementing $stealth modifier. It works similar to all other modifiers, just add it to any exception rule and it will disable Stealth Mode for that website specifically, even if the module itself is enabled. For example: @@||example.org^$stealth You can find more information about rules formatting on our website: [adguard.com/filterrules.html](adguard.com/filterrules.html)
  • [Changed] Facebook windows app added to default filtered apps list #974
  • [Changed] $replace rules should now have higher priority than other basic rules #1023
  • [Fixed] Adguard does not try to filter data: URLs any more #1007
  • [Fixed] $domain modifier now does work for blocking WebSocket connections #998
  • [Fixed] Adguard now doesn't ignore tag href attribute while constructing absolute URL #978
  • [Fixed] Error previously encountered while parsing a style tag with embedded svg #977
  • [Fixed] Language-specific filters are now detected properly from users keyboard layouts #401
  • [Improved] Adguard now can process websites names in punycode when adding them to HTTPS exclusions #962

Languages and Translations

  • [Added] Support for complex language codes #808 We have completely reworked applications localization system. This allowed us to significantly increase number of languages we can potentially support (this mostly concerns various dialects, alternative alphabets etc.).
  • [Added] Croatian language

Networking

  • [Improved] HTML content detection #855 Content type detection was significantly improved. This effectively means that Adguard will not interfere with those types of traffic which do not require filtering, decreasing the number of potential conflicts.
  • [Fixed] Web interface of TP-Link router is broken #844 Some of our users encountered problems with accessing TP-Link routers' interface with enabled Adguard. Upon investigating this issue we discovered a serious issue with WFP driver which resulted in problems with displaying some websites. As a result, we have improved communication with some specific web-servers.
  • [Added] Support for HTTP method REPORT #1020
  • [Fixed] Adguard can now detect HTML if there is an xml declaration at the document start #1011
  • [Fixed] ESET compatibility issue when Chrome browser would randomly hang #899
  • [Fixed] Data is now read to end after blocking a POST request #916
  • [Fixed] Issue with unexpected connection reset with TDI driver #1025

Install/Update

  • [Fixed] Blank dialog while updating from 5.10 to 6.0 #924
  • [Fixed] CMD window is no more shown on Adguard update #935
  • [Fixed] An issue when update errors were shown as valid updates in tray notification #993
  • [Fixed] Adguard now detects Chrome in 'Filtered apps' on Windows 10 insider build #972

Minor

  • #914, #927, #948, #946, #945, #944, #1014, #1029
  • [Fixed] Issues in Windows 10 Insider Preview build caused by SHA-1 certificate used for network drivers. https://github.com/AdguardTeam/AdguardForWindows/issues/915

    Let us elaborate a little on this one, since this change stands out as the most important one in this update. Recently we have noticed, with the help of our beta testers, that SHA-1 certificate previously used to sign our network drivers, was in a process of being deprecated. Effectively this means that users of Windows 10 Insider Preview were not able to enable Adguard protection. We have signed our network drivers with new certificates, and now all users will be able to run Adguard without any problems.
