Ever since I upgraded to Firefox Quantum 57.0 I always get the error message "'Your Firefox profile cannot be loaded. It may be missing or inaccessible " every time I open Firefox. I click on "OK" then I can use Firsfox but it is very slow and the error message pops up 2-3 other times.

I tried the different solutions suggested on this forum such as reinstalling Firefox, renaming the profile.ini file and lastlly deleting the profile.INI file.

None of these suggestions helped.

Can someone please help?

A possible cause is that the file path to the Firefox profile folder is containing non ASCII characters.

Do you have a Windows user account that has special Unicode characters?
