Can anybody that has Chrome and can actually do it, answer? Also, for Firefox 3.6 (latest version of ff), only those that can do it.
I'm not looking for somebody just pointing to an extension, but somebody that can use it in Chrome or Firefox 3.6.
I'm guessing your question is "Is it possible to search my youtube favorites using chrome or firefox without an extension?"
The answer is no. YouTube doesn't currently provide a way to search favorites.
There are advanced search options on the search results page but nothing to let you search your own favorites.
Jotpix offers a way to search your favorites (both private and public) and any users public favorites via their website - http://www.jotpix.com/YouTubeSocialSearch.aspx?s=favorites
I made a site that lets you search through your favorites
Just enter your username and click favorites then start typing in the search box
