Hi, can you please check your Cisco Extension by : Try Firefox Safe Mode to TEST & see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:

• Click the menu button , click Help and select Restart with Add-ons Disabled.

If Firefox is not running, you can start Firefox in Safe Mode as follows:

• On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
• On Mac: Hold the option key while starting Firefox.
• On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
  (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

When the Firefox Safe Mode window appears, select "Start in Safe Mode".

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

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

If Cisco is not the issue please try this : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Hi, actually do not be intimidated by it as it is really a step by step. I will condense it for you.

• Please download a New Firefox Full Version Installer from here :

https://www.mozilla.org/firefox/all/

• Then as Firefox uninstall does not touch your Profile (note should learn the 2) Uninstall Firefox

• Then open File Explorer or My PC and go to each of these folders to Check for a Mozilla Folder, is usually deleted these days but check here :

C:\Program Files , C:\Program Files(x86) & C:\ProgramData

• Delete the Mozilla Folder if found.

• Use the Installer you downloaded to reinstall Firefox.

Hope that is easier for you.

I appreciate the help and that you think that was "easier" but I have no idea what you are talking about
