Any one extension has guaranteed access to 30,000 rules.

One of the main issues of Manifest V3 is that it imposes a fixed limit of 330,000 rules for all extensions installed in Chrome. While they managed to produce a working content blocker based on Manifest V3, they concede that it has certain limitations that Manifest V2 content blockers did not have. The developers note that the new APIs of Manifest V3 caused a lot of headache during development.

Work on the extension started in mid-2021. Users of AdGuard do not need the extension, as the main solution runs system-wide. AdGuard MV3 Browser extensionĪdGuard published a new browser extension for Chrome and other Chromium-based browsers that is based on Manifest V3. Some Chromium-based browsers may modify the default behavior to support Manifest V2 extensions, but most won't, probably. In other words: extension developers need to update their extensions to be compatible with the new Manifest V3 or end development for Chrome. From June 2023 onward, Manifest V2 extensions won't run in Chrome anymore. Starting in January 2023, extension developers may no longer publish new Manifest V2 extensions or update existing ones. Google made some concessions, but went ahead with the launching of Manifest V3 in the company's Chrome web browser. Some browser makers, including Mozilla, maker of Firefox, stated openly that they would not implement the limiting changes of Manifest V3. The developer of uBlock Origin, who maintains one of the most respected content blockers, said that the release of Manifest V3 could mean the end uBlock Origin for Chrome. Extension developers, privacy advocates and users criticized Manifest V3 shortly thereafter. Manifest V3 defines what extensions can and can't do in the Chrome web browser, and any other browser that implements it. Google announced plans to release a new Manifest for extensions in 2018.

Chrome and Chromium-based browser users who have not followed the news regarding the future of extensions in the browsers, may need a quick explanation to better understand what is going to happen in the coming months and years.
