In my list of programs, there are 15 mozilla programs from 3.5.5 to 3.6.13 could I remove some of these versions and which ones should I remove without losing anything (Bookmarks, home page, ect.)?

When I go to add/remove programs, I noticed that there are 15 versions of Firefox listed. Is it necessary to keep all these versions? Since they each use 27.86 MB is this slowing down my PC? If I can remove any versions, which ones should I remove and will removing any of them affect my internet experience such as losing bookmarks or my home page?

You only need one version of Firefox installed, but you may already only have one version, the list may be giving incorrect information. Before you try to uninstall any check your Programs File folder to see how many versions of Firefox there are. By default it installs to C:\Program Files\Mozilla Firefox\

You can search your computer for a file called firefox.exe, there will normally only be one copy of that file in the above folder. If you only find one copy then you will only have one version of Firefox installed.

When uninstalling Firefox there is an option to "Remove my Firefox personal data and customizations", if you select that option it will delete your bookmarks, passwords, cookies etc.

Don't remove personal data if you decide to uninstall any Firefox version.

If you only ave one Firefox version installed (and that is most likely the case) then you can remove the other entries from the registry with the regedit.exe program if you are comfortable with editing the registry. Otherwise it is best to leave them or use a registry cleaner program to remove those entries.
