In the "appearance" area of my ad on area I have a program called Default 36.0.1. Since it showed up I have had difficulty in configuring my yahoo.com home page and mail appearance area. Can this appearance ad-on be un-installed? I cannot find it in my program area nor is there an un-install button beside it in the ad-on box. I have a Microsoft Windows 8.1 operating system and I believe the most recent version of Firefox which was working very well before this ad-on showed up on my computer.

The Appearance section of add-ons Manager is what lists any Themes you have installed in Firefox besides the default Theme as mentioned above.

There is the lightweight (think toolbar wallpaper) and the complete. https://addons.mozilla.org/firefox/themes/ https://addons.mozilla.org/firefox/complete-themes/
