The following issues and changes are introduced:

Firefox users may block WebRTC connections.

Performance issues in Adblock Plus 2.9 will no longer be an issue when Firefox 57 is released.

The browser extension is based on WebExtensions which means that it is fully compatible with Firefox 57 and newer versions of the web browser.Īdblock Plus 3.0 introduces new functionality, and some regressions and issues as well. The release of Adblock Plus 3.0 for the Firefox web browser ensures that none of this will happen. Mozilla would be painted in a bad light if the most popular extension for Firefox would not function anymore in Firefox 57 and the developer of Adblock Plus would likely lose a huge part of the user base, as users would migrate to other content blocking solutions for the Firefox web browser. It would be disastrous for Mozilla but also for the company behind Adblock Plus if a WebExtension version would not be available before the release of Firefox 57.

It has more than 14 million users according to Mozilla the second placed add-on, uBlock Origin, has 4.1 million users. Adblock Plus WebExtensionĪdblock Plus is the most popular Firefox add-on. One reason for that is that there are legacy add-ons for which no comparable WebExtension extension exists. The search redirects to Mozilla's main AMO website and is a hit and miss kind of experience. You find all disabled legacy add-ons listed there, and an option to find a replacement for each add-on.

Mozilla will move legacy add-ons to a new section on about:addons. The new version of the Firefox web browser breaks the traditional add-on system by supporting WebExtensions exclusively.Īny add-on that is not a WebExtension by then won't install in the browser anymore by then, or deactivated if a legacy add-on is installed already. Firefox 57 will be released in eight days to the stable channel.
