Firefox unable to load / over 30+ in Task Manager

[lucy]

When I click on FireFox it keeps coming up with the following message ‘Your FireFox profile cannot be loaded. It may be missing or inaccessible’

This message appears on screen for 20 seconds then disappears and then appears again, repeating this cycle.

Also noticed there are over 30+ Firefox processes in the task manager.

I’ve deleted Firefox reinstalled but it’s not fixed the problem?

Firefox doesn’t even load up because of the above problem repeating it itself,

Anyone have a fix?

The same thing happened to me, do you happen to have Kaspersky Anti‑Virus? I uninstalled it and then Firefox worked again, disabling it did not do the trick.
