Unpopular opinion: the Firefox hate is completely out of proportion.
Whether we like it or not, a lot of users are interacting with the internet through AI agents. Every browser larger than Firefox already has AI agents locked into the browser. Firefox is providing an option for people who would like to use it, and that's it. They're providing it in a better and safer context, in which users can define the scope of access that the AI has, which AI agent they want to use, or even use a local AI model.
A lot of people here will start simping for the Google-backed Chromium browsers, or for crypto mining browsers, or for browsers that are essentially reskinned Firefox.
I've used the beta version that's out now. There's a little pop-up when it updates that says, hey, would you like to set up your choice of AI agent? If you don't want one, you just click no thanks and skip it and everything else still works the same.
Maybe I'm the one with the clown makeup in the last panel, but I just don't see what the big deal is for everybody.
