I installed a dev version of Firefox to test a plugin.
Then I uninstalled the dev version, but now none of my profiles on the regular version work...
Please help me, I really need my old browser history and cookies.
When I try to use one of my old profiles, I get "You've launched an older version of Firefox" and it tells me to either Create New Profile or Exit.
I read online that people add "-allow-downgrade" to the Windows shortcut, but this does nothing for me.
Thanks you and please help!
