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.

That is the default theme of Firefox, it can't be removed and is always included, it's been there since you installed Firefox you just didn't notice it.

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/
