(Toolkit :: Application Update, defect)

Software update hangs with 100% processor usage when user lacks NTFS write 
permissions on the update folder.

To reproduce:

1. Run Firefox once so that the 'Updates' and 'Updates/0' directories are 
created. Close Firefox.
2. Change the NTFS permissions on either of the above folders to disallow file 
creation and modification.
3. Restart Firefox. Navigate the menus to 'Help' -> 'Check for Updates...'. 
Firefox should display the Software Update UI.
4. Once an available update has been detected, click the 'Download and 
Install' button. Firefox will begin the update process, but will stop almost 
immediately with the status string 'Connecting to the update server'.

In past builds the throbber and progress bar would simply spin forever, but 
with this build the UI actually freezes and the processor usage shoots sky 
high. No crash is ever observed, but Firefox must be forced to close.

This is a spin-off bug from bug 309183, destined for a fix after FF1.5b2, I 
think.
