i can not get firefox developer edition to open. it flashes up in task manager and disappears.
it has been working fine and then stopped working a few weeks ago.
i when i try to open (even in administrator mode) it, i see it pop up in task manager and then it immediately disappears.
here's what i have tried:
i uninstalled and reinstalled firefox developer 64 bit edition.
I uninstalled, turned off my firewall, and tried to reinstall firefox developer 64 bit edition.
i renamed the old firefox data folder to something else, uninstalled, turned off my firewall and reinstalled firefox developer 64 bit edition.
i tried running firefox.exe -P (to create a new profile) but that won't open either.
i uninstalled, looked for other files with firefox in the name, and tried to delete them. although i am the administrator, it would not let me because it needed administrator rights.
any other ideas?
