Microsoft Edge is about to lose uBlock Origin, too

When you purchase through links in our articles, we may earn a small commission. Microsoft's Edge team has posted a timeline for migrating away from Manifest Version 2, the extensions foundation upon which uBlock's superb uBlock Origin adblocker lives. Remember how one of the best adblockers, uBlock Origin, was effectively killed by Google Chrome? Throughout 2024 and 2025, Google said that it was migrating its extension support from what is called Manifest, from version 2 to version 3. Now Microsoft says that it is following Google's lead, and beginning that transition as well. Ads stink, and anyone who says that they don't affect productivity has never turned off an adblocker and tried to surf a major media site, including our own.
