Firefox opens and a porno picture fills my screen! Please remove this from FIrefox on my machine.

When opening Firefox a pornographic site immediately opens. This needs to be immediately removed. We've never gone to this, don't know where it came from, and have looked through most settings to try and find where it came from. It's automatic and it's inappropriate.

Sorry to hear about this problem. Please note that neither Mozilla nor support forum volunteers have access to your computer to change what pages appear in the browser. So we'll give you suggestions to try.

As a starting point, is the unwanted page set as your home page? You can test by holding down the Alt key and tapping the Home key on the keyboard, or by launching a new window using Ctrl+N. If it is your home page, please see the following articles:

If it is not your home page, it could be that an add-on does this at startup. Could you test in Firefox's Troubleshoot Mode? In that mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is running:

You can restart Firefox in Troubleshoot Mode using either:

  • "3-bar" menu button > Help > Troubleshoot Mode...
  • (menu bar) Help menu > Troubleshoot Mode...

and OK the restart. A small dialog should appear. Click the Open button.

If Firefox is not running:

Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.) A small dialog should appear. Click the Open button.

Note: Don't use the Refresh without first reviewing this article to understand what will be deleted: Refresh Firefox - reset add-ons and settings.

Any improvement?
