I'm having a problem where Chrome won't ever fully start (cursor just spins indefinitely and can't use the any menus or buttons in Chrome). I think it is due to an extension I installed but since the browser is unresponsive, I can't do anything through Chrome itself.

Is there a flag to disable all extensions for Chrome or a config file I can manually edit to disable extensions so I can figure out what exactly is causing it? I'd prefer to not have to blow it away and reinstall as I might just install the offending extension again (assuming that is what is causing the issue).
