On startup, firefox asking for master password

more options

Hi

Today Firefox started to ask "master password" on startup. Yes I use master password, but Firefox never asked it on startup. Why this could be happening? It does not matter what startup page I load, it could be blank page or any other. No sync or other Mozilla account is connected. Tried to disable all add-ons, does not help. Firefox version: 63.0.3 (64-bit).

Chosen solution

Yes I had my suspicions about kaspersky. Now I reinstalled it, and problem is almost gone. Now MP on startup appears only one time, when computer is restarted.

Hi spdgnzls, I suggest starting a new question about this part:

And if "security.enterprise_roots.enabled" is not set to true, then FF is unusable!

You may have a "man in the middle" of your web browsing connections.

The inability to access sites like Yahoo Finance and many other similar sites was caused by a suggestion from jscher2000 on mozilla support as a way of stopping two master password request boxes from opening when Firefox opens - to set enterprise roots enabled to 'false'. It DID stop the double password request boxes, but made secure sites unavailable. Changing the Avast settings as he suggested did not help. Set the above to 'true ' and I can access all my sites, but have the double master password boxes again :(

Ie; no complete solution to my problem and no idea how to proceed from here.
