How can I go back to 3.6.17?

more options

Firefox automatically downloaded 3.6.18 and I lost my Tabs. Then I downloaded 4 then 5 and hate them both. In 5 my mouse is very jerky. 3.6.17 works best for me and I want to go back to it. HELP how do I go back? Thx,

For security reasons, it would be better to use 3.6.18 and fix the issue with your tabs.

Can you explain what you mean about losing your tabs -- did your Bookmarks Toolbar become blank or disappear completely?

Before making further changes, I recommend backing up your Firefox settings in case something goes wrong. See Backing up your information. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
