I updated firefox and when trying to open it received an "EntryPoint Not Found" error.

The procedure entry point sqlite3_backup_finish could not be located in the dynamic link library C:\Program Files\Mozilla Firefox\xul.dll

Click okay then get the message

"couldn't load XPCOM."

It would appear I need to delete firefox and reinstall, unless a method exists to revert.

If I delete and reinstall how do I retain bookmarks, history and open tabs, etc.? I need to keep my tabs, history and bookmarks.

An error message like XPCOM missing or about platform version or entry points not found can happen because of a failed Firefox update that left you with a mixture of old and updated files in the Firefox installation folder. This can happen in case security software was keeping a handle of some of the files in the Firefox program folder preventing Firefox from replacing all the files. You need to do a clean reinstall and remove the Firefox program folder to ensure that all files are replaced. You may have to disable security software temporarily in case the problem persists.
