Absolutely. I would never recommend any of these offshoots over stock. You can literally set it up the same exact way if you want, but still get same day security patches and updates.

Only reasons if heard is faster updates if you use base Firefox (w/ arkenfix user.js). Also the styling (brand icons and such) for librewolf are detectable. Mullvad is better than librewolf for antfingerprinting.

I switched to it a couple weeks ago from FF/arc. No issues so far, and I’m pretty happy.

I assume Sync doesn't work for history and bookmarks if its not using the FF servers.
