Reinstall Firefox without previous settings

more options

Recently my tabs and tool bar color scheme all turned white. I have gone through Add Ons and Themes and changed/enabled the default, as well as other color themes. The tabs still don't appear properly. They all blend together, whereas previously I could see an outline for each tab. I then wanted to uninstall firefox and then install it again. The problem I am having is that when I go to install it (after downloading it again), it recognizes I previously had it installed and it only allows me to install it again with whatever is left behind from the previous install. My PW, History, Login, etc., are still present on the new install. My question..... How can I install FireFox and have it be complete new? I don't want any previous info on there. Something has messed with my application internally and I don't know how to isolate it and would prefer a completely fresh slate. I believe my PC is operating Windows 10. I have been using the same system and Firefox on this PC for 4 years now, without previous issues. Thank you.

Hi, this is a new design launched in Firefox 89:

https://blog.mozilla.org/en/products/firefox/new-firefox-coming-june-1/

You can modify the background color of the toolbars easily with an add-on theme. If you prefer the colors of the "Default" theme from Firefox 57-88, someone created one that emulates it. You can give it a try here:

https://addons.mozilla.org/firefox/addon/photon-colors/

If that color doesn't suit you, the Firefox Color extension lets you create your own theme:

https://addons.mozilla.org/firefox/addon/firefox-color/

'But... the vertical dividers can't be restored by a theme.

If you can't get used to thinking of the site icons as markers for where each tab starts, then there are some workarounds we could suggest.
