Browser-extension Release - AdGuard versions

AdGuard Browser extension
version 2.10.11 from October 2, 2018

Among important changes is a fix to the Assistant "block" button issue and a new "Save filtering log" feature that will come handy for filter developers and in some cases of troubleshooting via support.

  • [Added] An option to save Filtering Log when reloading the page #1074
  • [Fixed] AdGuard 2.10.8 extension for Edge blocks Spotify web player playback #1090
  • [Fixed] Assistant preview doesn't close #1083

AdGuard Browser extension
version 2.10.8 from August 28, 2018

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 Browser extension
    version 2.9.2 from April 11, 2018

    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.
