Uninstalling the google toolbar appears to have fixed the problem! At least, I could go to https://signup.tiscali-business.co.uk/ immediately. The first time I tried http://www.barlays.co.uk/ and 'login' I got the same error, but after a couple of retries it was fine.
So this needs some more exhaustive testing, but that may be where the problem lies. -- Update of Firefox disables PSM (not more SSL or saved passwords) https://launchpad.net/bugs/89023 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
