I uninstalled firefox, removed all traces of firefox "directories, registry entries" then installed v5 AND I get sqlite3.ddl is missing from your computer. Does firefox use sqlite3.ddl and js3250.dll?

I used v4 with no problems, upgraded to v5 and dll problems began. I installed an older version of firefox and noticed sqlite3.dll was part of the install. Ran the upgrade and the upgrade process removed sqlite3.dll.

I tried saving the sqlite3.dll from the v3 firefox install and placed it in the window/system32 folder. Firefox then reports an invalid entry point into sqlite3.dll and js3250.dll

You can't do that. Such files are for a specific Firefox version.

You need to do a clean reinstall.

Download a fresh Firefox copy and save the file to the desktop.

  • Uninstall your current Firefox version.
  • Do not remove personal data when you uninstall the current version.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

  • It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Doing fresh install dis not solve the problem of the missing sqlite3.dll.

How can delete the firefox profile when firefox does not run. Is it published where the profile is stored?
