Earlier this year, Google Chrome annoyed a whole lot of adblock users by killing support for Manifest V2 extensions. It's a Manifest V3 world now, which means the permissions and APIs that thoroughgoing adblockers like uBlock Origin rely on are a thing of the past on Chrome (it's since been replaced by a pared-down version: uBlock Origin Lite). Now, Microsoft Edge is following suit: "Over the next few months, MV2 extensions will be gradually turned off by default," says Redmond.
All of which is red meat for the folks over at Mozilla Firefox, the free-and-open-source browser that once reigned supreme on our PCs before Chrome came and ate its lunch. In posts across social media, Firefox kicked Edge (and Chrome) in their self-inflicted bruises, declaring that "Our support for uBlock Origin isn't going anywhere", a post that came days after it wrote "Reminder that you can still just… use ad blockers on Firefox. Wild concept, we know."
