Hi,

Please also try opening Firefox in a new profile.

If you have security software (antivirus, firewall etc.) installed, you can try deleting all existing instances of Firefox and related files in all the different configuration areas/modules of the security software. Instead create new allow/trusted rules for Firefox + its related processes. Even otherwise the security software may also ask again when Firefox is started and you can try to allow/trust at that time. Please see this.
