It’s not like Firefox doesn’t collect user data at all. Vivaldi is hard to seriously fault in that area.
Unfortunately, Firefox lacks some features that make it a little clumsy at times. But for general use it is great. I keep it installed and use it almost every day because I believe in the browser engine and the need for diversity in that area. It’s just not for every need. At least not for me. That’s where Vivaldi and Edge have to help.
I’d venture out there and say Vivaldi in functionality and customisation.
Privacy probably not, though Vivaldi does quite well.
Sadly it’s a Chromium browser.
Edit: a simple comparison.
highly anticipated Windows 12
Microsoft wants to make the taskbar appear to float above the desktop by separating it from the desktop and rounding off the corners
Who gets excited about that!?
Plus, all the (always online, storing everything we say, type and look at) AI features should be looked at critically and not with high anticipation.
Stackoverflow gets quickly steamrolled by AI.
We’re not 100% there yet, but the writing on the wall is there. Just my opinion, of course.
