Firefox hangs on plugin loading, not marked by OS as unresponsive, must be killed with task manager, works fine with other Windows 7 users on this computer.
I'm not sure what plugin is the problem but when the plugin_container process loads, firefox hangs and becomes unresponsive. Windows 7 doesn't recognize it as such, however, and I have to kill the process with TaskMgr.
The problem does NOT seem to be the plugin container itself because when I add the MOZ_DISABLE_OOP_PLUGINS environment variable to windows the problem still happens, just internalized to the firefox process.
Since I remote into the box a lot I have other users, all of which have no problems with firefox. It's only localized to the one user.

My suspicion is Flash, since that probably is the most commonly used plugin. Try disabling the protected mode feature, since that is currently being debugged. See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?
Yes, many thanks.
I wound up fixing it with a system restore but will try this if it happens again.
