I am so frustrated with Firefox 5. It is so difficult to understand their new use of tabs. Is there any way of going back to Firefox 4, even though Mozilla will not support it any longer?
Tabs are the same way in firefox 4 ;)
You can adjust the tabs in version 4 and 5 to appear like they did in Firefox 3.
try to adjust with 5, it's secure
Well you have to uninstall firefox 5 and then reinstall firefox 4, prior make backup of your bookmarks.
