complete error message titled firefox.exe - Application Error

The instruction at "0x10007dba" referenced memory at "0x7c90e514". The memory could not be "written".

Click on OK to terminate the program Click on CANCEL to debug the program

After clicking OK or CANCEL the program does not start

I've tried uninstalling and reinstalling with the same problem

Has anyone found a solution to this? I hate using Internet Explorer.

Hi gfrancom-

I do not know precisely why you are getting this error. I would suggest doing a full uninstall, and then installing the latest 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.

I hope that helps!
