I added a "Simpsons" theme from the add-ons, but it does not show up on my page.

I used to have a Simpsons picture above the tool bar which disappeared after Norton did a scan check. I went to add-ons in the menu and selected a new one to replace it, but it does not show up. I tried it more than once but nothing worked.

hello, it is a known issue that light-weight themes are currently not shown when firefox is set to never remember history (a.k.a. always run in private browsing mode) in firefox/tools > options > privacy. this will be corrected in the upcoming firefox release.
