Been using Firefox for as long as I can remember now. Never had a reason to switch away, and I’m feeling rather vindicated.
There was a period some years ago where Firefox and Chrome were leapfrogging each other: Firefox would get slow and crap so I’d switch, then Chrome would get slow and crap and I’d switch back to FF, and so on. I’ve been on Chrome for quite a while it seems, until this development with uBO, well for me the internet is unusable without a shitblocker, so that’s the end of Chrome. Thankfully FF is up to the job.
I switched to Chrome probably a decade ago, because at the time it was significantly faster. I switched to chromium at some point and ended up back on Firefox when Google’s password manager stopped working on every browser except Chrome. Firefox is noticeably faster these days and doesn’t crash as often.
