Support/Firefox.Next

This is a rough list of enhancements that could be made in Firefox.next (3.7?) that would make troubleshooting Firefox users' problems simpler for our SUMO community.

• Diagnostics window that does a bunch of basic checks and offers tools to simplify self-diagnose
  • Would be available as a Help menu item, e.g. Help » Diagnose (perhaps an about page, e.g. about:support)
  • Items to diagnose and report in this window:
    • Integrity of files (places.sqlite, etc)
    • Any disabled features that may cause problems (cookies, javascript)
    • Active extensions
    • Connectivity
  • Available tools for self-diagnose:
    • Button to restart Firefox in safe mode
    • Button to open current profile folder
    • Button to copy all diagnostics info to the clipboard
• Automatic gathering of info about active extensions using Javascript, with UI similar/identical to geolocation [1]
• Automatic background diagnostics when idle and not on battery power?
  • The above about:support diagnostics could be done in the background when Firefox is idle to catch problems without the user actively seeking to solve them
• Automatic check of connectivity problems -- especially after upgrading to a new version of Firefox
  • Could it connect to the internet before it upgraded?
    • Likely a firewall issue
    • Link to relevant support docs on SUMO
  • Can it connect to to some trusted/reliable websites?
• If Firefox crashes more than once on startup, show a dialog asking if the user wants to launch another browser to troubleshoot on SUMO - would obviously have to be a native app that doesn't crash itself
• In the post-crash "This is embarassing" dialog, show link to "Search for solution to my problem" that performs a search on SUMO similar to crash-stats already works
• In the Socorro dialog, add button to search for solution to my problem (same as above)

Other general feedback

• Go through XUL help pages and make sure we link to relevant SUMO info where appropriate
• Offline mode is confusing
