Downgrading from Firefox 4 to previous one

[Ikshana]

I recently have downloaded and installed Firefox version 4 on my system. But I am experiencing various problems associated with it so I want to downgrade or change it to previous other lower versions of it without losing my bookmarks entries. I would like to work on my system as it was running fine before. Will uninstalling my Firefox version 4 will automatically solve my problems? How can this be possible? Please help.
