I have the latest version of both Flash and Firefox, but nothing that requires flash works. Youtube videos don't work, gaming sites don't work, not really anything. It works sometimes when I restart windows altogether, but most times it doesn't. I have no clue why this is happening. Can somebody help me? My Youtube levels are dropping to an unsafe level...

Hi, did you try in safe mode?

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • On Windows you can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
  • On Mac you can open Firefox 4.0+ in Safe Mode by holding the option key while starting Firefox.
  • On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
  • Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

FirefoxSafeMode

Once you get the pop-up, just select "'Start in Safe Mode" Safe Mode Fx 15 - Win

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.

The same thing happens in safe mode, so I don't know what's going on. I've tried resetting Firefox before, but that didn't work.

Does Flash work on the Adobe test page?


Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

The message in the image pops up where the ad on the top of the YouTube home page is usually, if this means anything. I don't know what the rest says after it's cut off, because this is all it shows.
