Update to Firefox 4 has frozen. Computer still indicates CPU and memory usuage but it never finishes. Previous Firefox no longer works. Upon restart and clicking Firefox, updater just goes into same frozen state. Updater appears to be defective.
CPU usuage is at 13%, memory for Firefox updater is 28,348K. Have tried shutting down and restarting. Everything looks normal except that the start menu shows Firefox twice. At this point there is no CPU usuage and Firefox is not running. Clicking on Firefox seems to start up the updater (same CPU and memory as during original update), but there is no window. Only taskmanager indicates anything is running. The other Firefox icon in the start menu has no effect other than to list Firefox twice in the taskmanager, but the new one has no CPU or memory.
