Does anyone know how I can fix this? For some reason there is a Firefox URL bar floating over the search bar. Trying to learn my way around Matrix/Element, and this is kind of getting in the way.
Firefox does not support web apps. But Linux Mint wanted web apps and they molded Firefox into kinda supporting it. But it's not perfect.
Personally, I would recommend either using Chromium for web apps or installing the Element desktop app.
