I know the mobile browser space is just weird overall, especially Firefox forks, but it definitely stood out to me. Things that work totally fine in Librewolf out-of-the-box were totally busted, and most settings are inaccessible.

I'm still keeping an eye on it though, as Fennec leaves a lot to be desired, and using a chromium-based browser like Vanadium won't do it for me because I rely so much on the cross-platform sync functions.
