Portable firefox on my U3 drive has not functioned since it auto-updated while in use.
It has been unable to launch since the update. It generates an error message: " firefox.exe has generated errors and will be closed by Windows , an error log is being created".
Uninstalling Firefox and reinstalling it to the U3 drive did not help. Switching computers does not help. The Marathon browser generated the same error message but after uninstalling/reinstall now works. Thanks!
