This bug may have been reported but I could not find it. Self explanatory. Go visit http://www.1stbank.com press the Login in button. If you have root privileges, the page renders correctly after several seconds. If you are not root, Mozilla just hangs (or rather, the progress indicator never stops).
A known problem. This should be fixed when PSM is built into the Linux Mozilla builds. *** This bug has been marked as a duplicate of 49507 ***
Verified dupe of bug 49507: "psm does not work, when run as a different user in unix. (causes hang/freeze)"
