I don’t use edge either. I’m comparing it to chrome.

On Firefox, for some reason, the tab and tab text colours are as if you had high contrast theme on. They are horrible to look at.

There are also a bunch of small, but over all annoying, QoL features missing. For example when you have a tab open from a tab group and you click the tab group to minimise it, it doesn’t minimise the tab you have selected.

Just small things like that. It just feels unfinished.
