I have been using Firefox for years. I know what Tab Mix Plus Options are. But I got a new computer and the first thing I did was download the latest version of Firefox - 3.6.12 to be exact. I went in and changed my Tab Mix Plus Options to the way I wanted it, but they aren't working. For example, I have my single window mode enabled, and have all my links opening in new tabs. But it just won't work! I am so confused. I have tried everything. If I type in a new address in the address bar, or a google search, or a bookmark, nothing happens except that I get a new tab opened with the tab name 'untitled'. It won't even switch to the newly opened blank tab! I also have to manually go to an opened blank tab in order to be able to go to an address. Then if I am already in a website, and I choose something that used to take me to that link, now it opens up a whole new window! Please help! I am very confused and FRUSTRATED!
