Hi, I have two questions. First question is, how do I perform a clean install of Firefox? It seems when I uninstall it and reinstall it, I get prompted to restore everything to the way it was (without any alternative option). I would like to install it fresh. Second pertains to the attachment. The color of the tab bar changed to blue. I run the dark theme and before it would remain black all the time. Now it seems that it is only black when the browser is NOT the active window (in the background the tab bar goes back to black). I don't seem to have this problem with the Chrome browser.
