The autofill function often does not work as intended, which is undeniably a nuisance, but I can't really complain about anything else.

EDIT 1
The extension icon has disappeared from my browser (Mozilla Firefox) and I can't bring it back. Meh.

EDIT 2
I just had to close all the open windows of the browser and then when I reopened them Bitwarden's icon was right back where it was meant to be. Still no idea why it did that but whatever, it has been working alright for quite a while now
