    Hello mb4ever,

    Any particular time Firefox do not work?  After usiing another program?  Download a file?

    1. Check if an addon is interfering.  Go to Tools > Addons and disable the addons. Click OK.

    If Firefox does not open, go to Start > Programs > Mozilla Firefox > Mozilla Firefox (Safe Mode)

    2. Check if a program running in the background is interfering. Disable firewall, antivirus, antispyware, spam blocker, and desktop programs.

    3. Clear your cookies and cache files. Go to Tools > Options > Privacy tab. Under Private Data, click "Clear Now" button.  Click OK.

    4. If no joy, your profile is corrupt. Create a new Firefox profile

    Then migrate your settings to new profile

    5. Run Firefox Standard Diagnostics

    6. If no joy, back up your bookmarks.  Uninstall Firefox and delete your Firefox profile files.  Then do a clean install of Firefox.

    Hope this helps!
