Using FF5 on Win XP SP3. When I go to a site either by directly typing in the URL , using a bookmark, or from a Google search, clicking to a different page ON the SAME site even just once results in multiple entries of the SAME URL in the Back Button menu. I have 5 entries for this help page I'm typing on now. If I were to use the <- Back button, I would have to click it 5 TIMES to go back to a previous page. This has only started since upgrading to FFox 5 from 4. This started immediately after the upgrade to 5. The only NEW Add On/Plug in was the ant.com vid downloader. I have removed it, cleaned out the registry keys pertaining to it, restarted the computer after using CCleaner: nothing. Same problem. Please help as this is getting annoying having to click and hold the back button down and then clicking several URLs down to one that will take me back to the previous page. TM
