Hi!

After update to 56.0, I was getting multiple following messages when starting and/or using Firefox. Eventually, all my bookmarks loaded without problem, but the error windows appeared consistently:


"Your Firefox profile cannot be loaded. It may be missing or inaccessible."


Attempted solutions (with no success):

 - Delete %appdata%/Mozilla/Firefox/profiles.ini file
 - Delete the whole %appdata%/Mozilla/Firefox folder
 - Re-install firefox
 - Delete the %appdata%/Mozilla folder, delete C:\ProgramFiles\Mozilla Firefox folder and re-install
 - Remove old profile and add new one using "firefox.exe -P"
 - Repeat some of the above 5x

Working solution: Reboot

 - I noticed Kaspersky antivirus was demanding restart after its own update.
 - Firefox error said "inacsessible", and antivirus frequently locks out our files during development.
 - Kaspersky forces its plugins into browsers, so I gave restarting it a try.
 - The Firefox works after reboot with no errors even with the original (restored) contents of the %appdata%/Mozilla folder.

Suspected cause of the problem:

 - The Kaspersky automatically installs its extension into browsers (even after manually removing or disabling them). 
 - I suspect that the updates/installs somehow conflicted.

EDIT: Reformatting for better readability. Added missing info into "attempted" solutions.

Hi, thanks, but this issue differs from all your linked ones in that it is *persistent* even after wiping all folders and reinstalling Firefox.

I have added more information into the original question. The working solution is also included:

Reboot the system.

Have you contacted Kaspersky support? As a test, disable Kaspersky. Is the problem still there. Note: just start Firefox. Does it load properly?
