how do I revert to my old version of Firefox? You know, the one that actually worked!


I recently upgraded to a newer firefox version and I am very unhappy with it. How can I revert back to my older version - the one that actually worked. Also I hate the restore last session feature. It raises huge security concerns when children have access to my computer.

Check and tell if its working.

What are the problems you are facing by using Firefox 6 ?? We might be able to help you resolve those issues.

Starting with the release of Firefox 6, the previous versions of Firefox (4.0.x and 5.0.x) are no longer maintained with Security and Stability updates. Firefox 3.6 is the last previous Firefox version that is still being maintained.

Firefox versions 4.0.x 5.0.x contain Security vulnerabilities that are known and could be exploited by some websites to gain unauthorized access to information or to disrupt critical processing. Only the Latest version 6.0 and an Older version 3.6 of Firefox are secure against these known vulnerabilities.
