Browser-extension Release - AdGuard 版本

A small but important release. We’ve added a new pseudo-class :is() and upgraded extended CSS to v1.3.8. :is() is a CSS pseudo-class function that comes in handy for writing large selector lists more compactly. Now AdGuard AdBlocker extension supports this functionality.
Another brick in the wall: building our perfect browser extension. It seems that the few latest updates passed without notice – it’s no wonder ’cause we didn’t show to users any visible change. Yet, don’t let yourself be disappointed with the same old mantra: Scriptlets, Extended-CSS, and filters. They matter. So, we’ve updated Scriptlets to v1.3.13 and Extended-CSS to v1.3.6. AdGuard Assistant has been updated to v4.3.37. Plus, we’ve added new translations and filters to this version.
When you're on a journey to the perfect ad blocker, every step matters. Even if it's on the smaller size like today: in this update, we only touched on scriptlets and extended CSS optimization.
The new version of AdGuard AdBlocker extension has been released. We’ve updated the scriptlets, locales, and extended CSS — and that’s just the tip of the iceberg. This beta harbours many secrets: many changes remained under the hood, but rest assured, they will improve the app’s performance.

版本 3.5.12 自 2020年8月17日
The release of AdGuard AdBlocker extension v3.5.12 was preceded by four betas the version numbers of which look like Fibonacci sequence: 3.5.3, 3.5.5, 3.5.8 (and 3.5.12 falling out of line)… Seems like we’re getting close to the golden ratio! We hope that you’ll find the changes we made to the extension beautiful and well calibrated.

AdGuard 浏览器扩展
版本 3.2.1 自 2019年7月3日

Your average grocery list is probably longer than this update’s changelog, but don’t let it fool you. We introduce two powerful new tools that are going to serve well to filtering rules creators and will noticeably improve the ad blocking quality.

[Added] Scriptlets support #1366

Scriptlets is a powerful ad blocking instrument. You can say that scriptlet is an internal script (a mini-program) that we install in the extension, and then execute that script with the help of filtering rules. Putting it simply, scriptlets allow us to modify how the code of the web page behaves. As for the practical use, this helps to block anti-ad blockers, for example.

[Added] $redirect and $rewrite modifiers support #1367

They are practically the same modifiers, and they allow to substitute resources. If you are not a custom filtering rules aficionado, don't bother with it. Just know that it is yet another instrument in the hands of filter developers that helps efficiently block ads.

We should mention that both $redirect and $rewrite modifiers are still kind of working in test mode, but they are fully operational and you should feel free to use them.

  • [Changed] The browser action UI on internal browser pages #1433
  • [Changed] Manifest file has been updated #1419
  • [Fixed] CSS rules exceptions don't work #1412
  • [Fixed] "Allow search ads and websites' self-promotion" checkbox doesn't correlate properly with "Self-promotion" filter #1287
  • [Improved] uBlock Origin syntax recognition #1383, #1428
AdGuard 浏览器扩展
版本 3.0.13 自 2019年4月16日

After a series of hasty hotfixes we are happy to finally do a full-scale release. It may be not the biggest AdGuard browser extension release of all times, but it’s something. Inside you will find some small-ish changes and of course more bug fixes! This time, they were not so urgent, though.

  • Changed] "Mobile ads filter" is enabled by default on the Firefox for Android #1307

AdGuard 浏览器扩展
版本 3.0.8 自 2019年3月7日

As they say, you can't have a good release without a hotfix. Or maybe they don't say that, but we sure need one.

In this update, we fix a particularly nasty bug that causes high CPU load because of some filtering rules.

AdGuard 浏览器扩展
版本 3.0.7 自 2019年3月6日

New AdGuard Browser Extension follows the trends. As if ads were not bad enough, the web today is teeming with trackers. Big companies want to know everything about you, and AdGuard is here to stop it. The new Stealth Mode is designed specifically to protect your online privacy — an entire new module dedicated just for that. But that’s even not the first thing you will notice. Of course, the new design will steal the show. Let’s have a closer look.

[Improved] Renewed design

Fresh icon and menu designs that make interface more natural and user-friendly, with a big ‘On/Off‘ switch. Brand-new ’Statistics" tab creates charts based on your blocked ads statistics, with the ability to show different types of data: total, filter-specific etc.

Also worth mentioning is the User filter. It has undergone a few changes too. The new luminous element highlighting and auto-save function, as well as a unified text field for filtering rules should make editing more convenient. The text box can also be resized to your liking.

[Added] Stealth Mode #283

We took online privacy protection in our extension to the next level by adding the Privacy module, which until this day existed only in the standalone AdGuard for Windows app. Although it doesn’t have the full capabilities of its desktop parent yet, it still makes the extension all the more effective for protecting privacy against trackers and analytical systems. It already gives you a wide range of privacy-related options (each explained in the tooltip), but we will surely add more in the future updates.

[Added] Filter categories #1068

We changed the way in which the filters are presented to users. Instead of listing them all together, we combined the filters into semantic groups. Each group includes filters that serve some particular goal. For example, filters that block ads are grouped together, filters that block trackers and serve privacy purposes will be united into a different group, etc. It is possible to enable and disable all filters in a group at once.

[Added] ‘Filters update period‘ setting #596

Before, filters were automatically updated every 48 hours (default period), now you can adjust the frequency of automatic updates (by choosing from options: every 1/6/12/24/48 hours) or disable them completely, in case you prefer to update them manually.

[Added] An option to disable integration mode while keeping the extension up #1012

If you already have the AdGuard app, our browser extension may become a very useful additional tool, which can completely replace the browser-based ’AdGuard Assistant" module (learn more). It’s called Integration mode and now you can turn it on or off in the ‘Other settings’ tab.

AdGuard 浏览器扩展
版本 2.10.8 自 2018年8月28日

This update adds several minor-ish (although filter enthusiasts will argue) features to the Filtering Log and improves ad blocking quality. You'll find an array of bug fixes, as usual.

[Added] Element hiding rules highlighting #1053

Applied element hiding rules are now highlighted with yellow color in the Filtering Log. This will greatly help parse log entries. We don't need to prove it to you if you are actively using it :)

[Added] Wildcard character support in rules with domain modifier #571

Again, another treat for filtering rules creators. Previously you had to list domains old-fashioned way:, etc, and now you can simply use example.* syntax.

[Improved] Scripts are injected faster #1029

To efficiently block ads on the page we need a way to reliably inject our scripts before the in-page scripts are executed. A set of measures has been taken to ensure this. While there is still no 100% guarantee, the success chance has increased considerably — along with ad blocking quality.

    AdGuard 浏览器扩展
    版本 2.9.2 自 2018年4月11日

    Ho Ho Ho! Just kidding, it is not Christmas, but it might have very well been — isn’t every AdGuard Browser Extension release a special day for you? For us, it certainly is 🙂 This time we prepared a couple or two of quite important changes and improvements, to come along with a long list of more routine-ish fixes. Read on to find out the details.

    [Added] Integration with the new Assistant #956

    For a while now we develop AdGuard Assistant more or less independently, to later use it wherever we need — Windows and Mac apps use regular Assistant, Android and iOS apps use mobile version. Browser extension users encounter Assistant when they click "Block ads on this website" button. We will not go into the details here, those who interested can find the exhaustive changelog inside the Assistant repo.

    [Improved] `InsertCSS` to use instead of the content scripts #847

    There was a certain change in Chrome browser recently, that prompted us to respond by reconsidering the way we inject scripts and styles. The good thing is, thanks to this change we now have less bugs, more possibilities and were even able to make the extension more lightweight by reducing the amount of code.

    [Improved] ExtendedCss has been updated to v1.10 #980

    This change is on the technical side, but from the end user perspective it converts into better performance and better quality ad blocking, thanks to more tools being available to the extension now.

    • [Fixed] Extension can't detect it when you disable filtering in Adguard for Win via Assistant #989

    AdGuard 浏览器扩展
    版本 2.8.4 自 2018年2月2日

    Ad blocking has been enhanced in this version by adding support for several modifiers. We've also integrated the extension with our web reporting tool, details below. As usual, all spotted bugs have been fixed too, this mostly concerns Firefox version.


    [Added] Integration with #894

    A new convenient way to report any issues with websites, be it missed ads, false positives, unblocked social widgets etc. Just head to the problematic website, bring up the context menu and select "Submit a complaint" option. You will be transferred to and a wizard will take you through the required steps to report the issue — and most of the fields will be even filled out automatically. Try it!

    AdGuard 浏览器扩展
    版本 2.6.5 自 2017年8月22日

    A long time has passed since the last release. But we weren't sitting on our hands. We fixed a whole lot of various bugs, so most users will find something positive in this update. This version also contains some sweet additions that will be interesting mostly for rule creators.

    [Improved] $important modifier was added to the rule constructor: #626

    This one is a rather obvious: when you use the manual blocking tool to create a rule, you can now give this rule a higher priority by ticking the checkbox. The `$important` modifier was available before, but you had to manually add it via the user filter.

    [Added] $csp modifier support: #685

    This is strictly for the rule creators, as it requires the basic understanding of the Content Security Policy security layer.

    This modifier completely changes the rule behaviour. If it is applied to a rule, it will not block the matching request. The response headers are going to be modified instead.

    You can find the syntax and examples for `csp` inside the issue.
