Adblock Plus and (a little) more

Adblock Plus 1.13.3 for Chrome and Opera released · 2017-07-12 11:57 by Dave Vandyke

This release features a number of ad blocking improvements, bug fixes and some changes under the hood.


  • Added WebRTC connection blocking support, since those connections were being abused by some websites to serve advertising (issue 4455, 5087 and 5092).
  • Added support for the new advanced #?# element hiding filter syntax, which includes the new :-abp-has pseudo-class (issue 5094, 5220 and 5117).
  • Added a workaround to prevent websites from abusing contentWindow and contentDocument APIs to bypass ad blocking (issue 4586 and 5207).
  • Started allowing web requests not associated with a browser tab to be blocked (issue 5042).
  • Started using the webRequest API for the blocking of WebSocket connections instead of our workarounds when supported by the browser (issue 5027 and 5130).
  • Fixed a bug which prevented the “Hide targeted messages?” notifications from being displayed until the browser was restarted (issue 5019 and 5023).
  • Reduced the number of “Blocked script execution…” warnings that Adblock Plus causes (issue 4494).

    Silly question and if its been asked I cant find the answer so let me apologise, but what’s happened to updates for Adblock plus for Safari its still on 1.12.4?

    Reply from Dave Vandyke:

    Not a silly question at all. In the past Adblock Plus for Chrome, Opera and Safari were all based upon the same code. Unfortunately more recently we’ve had to keep Safari behind, so now only Chrome and Opera are based on the same code. (In the future the Firefox and Edge extensions will be based upon it too.) This was necessary in order to make use of newer JavaScript APIs and syntax which Safari (especially the older versions which we support) was not compatible with. The burden of sharing code there got so painful this was the only way forward.

    We have occasionally made small improvements to the Safari extension, but like you point out we have not performed a Safari release recently. If you’d like to run the latest version of the Safari extension you’ll need to use the development build. Have a read of this page for more information:

    Thanks for reaching out, Dave.
