ive switched to firefox for desktop windows for about 1 year now. Firefox is really capable and as swift as chrome. You also get a sense of less intrusiveness. Firefox also has the multi containers widget, though for me it breaks down after a while. The big difference now between firefox and chrome are things like automatic subtitles for anything running in chrome. So if a youtube or other video has no english subs, Chrome can do it. And soon, Chrome i going to go AI too. I'm not sure how firefox will survive that onslaught. I suspect mozilla will have a firefox fork partnering with a major competitor of google (eg: MS).
