One thing that annoyed me was how much more awkward it is to switch between two user profiles .
In chrome I have a work email a personal email, each with its own account, and a different look. I can immediately tell which I’m using, and can switch between them with the button at the top right.
I managed to mess around and find an extension which kind of does the same thing, so I’m no longer missing the feature, but it’s definitely jankier and doesn’t work as smoothly.
Also, I don’t know if it’s a bitwarden issue, but autofill hardly ever works properly.
Sometimes I want to pull a tab into its own window on the other screen. You’re not allowed to do this when the browser is full screen, only when it’s windowed. Annoying.
These are my only issues with firefox I can think of.
