My system is Windows 7 x64 in work domain. I have two Firefox launch icons in my Startup folder. One to launch in OWA to connect to work's Exchange and the other to gmail. Prior to update, both Firefox windows appear. For the gmail, it automatically logs in and for the OWA, it automatically selects private network and prefills my username. Now, only one Firefox gets launched and is only the OWA, but it does not preselect the private network nor does it prefill my username. The gmail instance does not get launched at all. On top of this, every time I shut down the system, the system complains about not being able to shut down Firefox and I have to force it to shut down. I have tried Firefox to login other sites and none of them now prefill usernames and/or passwords. The only time I get it to prefill now is to close all FIrefox windows and then relaunch them. That is, start Firefox and manually select private network, fill in username and password, close firefox and restart to get to OWA, this time, the private network is selected and the username is prefilled. No configuration has changed between the updates and I have checked to make sure Firefox is not deleting history, passwords etc. All help appreciated. Regards, Vlad
