Firefox 91 Private Window Certificate Error Exceptions

Hello,

After upgrading to Firefox 91 when I visit site with self-signed certificate in Private window I always get Warning: Potential Security Risk Ahead error even though the certificate had already been added to exception list while not in private browsing. It looks like in private window certificate exception store is not honored. There was no such an issue before version 91. This behavior is by design or it could be a bug ?

Thanks

This could be because of isolating PB mode windows (tabs).

  • about:config => permissions.isolateBy.privateBrowsing

Hi cor-el, Thank you for response. I'd tried changing the value of permissions.isolateBy.privateBrowsing key to false but it didn't solved the problem
