I'm mainly a Firefox user, but there are two cases when I fall back to another browser (Brave, in my case):
- I have to maintain two MS Teams account for the professional reasons. I use one account in the electron app, one in the Brave. So Brave is just a Teams client... (if somebody knows a better solution to handle multiple Teams accounts on desktop, I would be grateful for any tips)
- I have so many privacy/security enhancing extensions in Firefox, that some pages render/work incorrectly. I'm too lazy to disable the extensions, so in case I really need such a page, I switch to Brave.
Otherwise Firefox is more than enough, I would say more - it's better IMHO than currently available chromium clones.
