In fact, restarting firefox seems to solve temporarily the issue. Note that this also happens using iceweasel 9.0.1 (other computer, other profile).
When it happens, I can close firefox, restart it, it will lod my tabs without warning. After a while, it will complain about Untrusted Connection. Maybe you can try to load http://www.zeroforfait.fr/ in a tab, click on the black button labeled Espace client on the upper right. After a while, reload the tab and it should happen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/923531 Title: firefox is warning about untrusted connection but certificate is valid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/923531/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
