You can just disable the anti-fingerprinting features in LibreWolf and it'll work fine with online banking and stuff if you just want de-cluttered Firefox.
Thank you! I just fired up Librewolf and turned off Fingerprint Resisting and my online banking now loads my transaction history. This had been a big annoyance and why I hadn't completely switched. The recommendation I got 6 months ago was "just use Firefox for banking". Much appreciated!
