My wife is affected by this problem too - in firefox, independent of thunderbird.
Since the most recent update to firefox was applied (via the orange update icon on the panel), she has been unable to access her on-line banking. It's easy to replicate: enter URL http://www.barclays.co.uk/, then click on the "log in" button at the top left hand corner. We then get the firefox error about Personal Security Manager, sometimes after a very long delay. My workaround for her has been to install Opera 9.10, which works just fine with this site. Firefox has definitely, definitely been restarted (I can show with 'ps -auxw' that it's not running, before restarting it) Now, things are even stranger with another site. Go to https://signup .tiscali-business.co.uk/ and you should just get a redirect to another page. If I do this when logged in as my wife, it gives the PSM error. But if I do this when logged in as myself, it works just fine. This seems to imply that there is some stored state which affects things (although I'm unable to get a Barclays login page from either account). Possibly an rm -rf ~/.mozilla might fix the problem, but I would rather avoid this if at all possible. I compared .mozilla/firefox/*/prefs.js between the two accounts. Mine has signon.rememberSignons=false, whilst hers has signon.SignonFilename = "something.s". I tried using about:config to set signon.rememberSignons=false on hers, then stopped and restarted firefox, but that didn't seem to make a difference. My wife does use thunderbird, but I am replicating this problem directly within firefox, and indeed it's the same even if thunderbird is not running at all. P.S.

I had to use Opera to submit this comment too. When viewing https://launchpad.net/ubuntu/+source/firefox/+bug/89023 in firefox, clicking "Add a comment/attachment" just adds a '+index#' to the URL and jumps to the top of the screen - nowhere to enter any text. Whereas in Opera, there's a triangle next to "Add a comment/attachment" which opens up an entry form. I suspect that's a separate bug, even though https is involved too. -- 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
