Honestly, I use FF as my primary on Linux, and Waterfox as my primary on Windows (just because it runs better than FF on Windows fir some reason). Vivaldi I use as a secibdary browser when:
- I need to visist a website that for some stupid reason doesn't open on FF
- When I'm studying or need to have several tabs open at the same time (by several I mean 100+, Vivaldi has really good tab management)
EDIT: I sent the reply without answering the question, I'm dumb. Anyways, some people like Vivaldi, some don't. If you ask in a Privacy forum (and especially Lemmy) you will find less favorable opinions of Vivaldi.
My suggestion at the end of the day is just try it out and try to make your own research on how it was created and who is in charge. As I've undestood until now (don't know if it has changed) is that the only thing proprietary about Vivaldi is the design(? Idk, someone correct me if I'm wrong) and that the CEO is not an.asshole (yet)
Didn't Texas say last year that they wanted to try being independent from the USA? I'm not from the US (anymore) so I'm not sure but I kind of remember that being said.
Isn't this like testing the waters in some way?
