I donate to the Mozilla foundation, and I love Firefox a ton. But I can’t seem to like the UI by installing a theme, and when I change it to look better the browser slows to a crawl. Does it really matter all that much if I use Chromium?
P.S. To the people from my last post regarding something similar, Firefox was too slow, I’m sorry, but I use Vivaldi instead of Brave because Brendon Eich can suck my dick.
Not OP, but I also prefer Vivaldi over Firefox. My reason may not be the same as OP’s, but for the sake of discussion, here it is. I simply can’t stand having tabs on top of my screen, and I’ll go to great lengths to have them on the bottom. On my private computer, I used to use Firefox with Tab Mix Plus, until Mozilla killed support for such extensions. I later managed to get the tabs to the bottom via custom CSS for Firefox, but every few releases the CSS stopped working and had to be recreated from scratch. So, I switched to Vivaldi. On my work PC, where only Edge and Chrome are allowed, my workaround is to work in separate windows instead of tabs, but that tends to get a little messy.
