I used Edge, because it's genuinely an extremely feature packed browser, but when Google announced the manifest v3, I jumped to Firefox.
Unpopular Lemmy opinion, but I hate it. Firefox always freezes on desktop, especially on YouTube. Firefox on Android feels like it was developed for Android 8.0 and never updated. And the worst part is there's a bug on the desktop version in the print preview window when it comes to printing shipping labels, so I have not been able to use Firefox for my company for over 8 months now.
I've reported the bug every time Firefox updates and the bug persists, but Mozilla doesn't give a shit. It's so frustrating.
