As much as I like Firefox/Librewolf, Vivaldi still has the upper hand in UI/UX. Workspaces, more feature-rich sidebar, one-click access to recently closed tabs right there in the tab bar, speed dial, tab stacks and other QoL stuff that makes just enough difference for me that I can't really daily-drive any other browsers. Until FF reaches feature parity (it's getting close, but still isn't quite there yet) I don't see myself migrating anytime soon. Quess I'll just need to rely more on AdGuard DNS and Vivaldi's built-in adblocker if uBlock becomes neutered on Chromium...
