I can't open the customize toolbar window
When I choose customize from the menu on the toolbar, nothing happens. when I type "about:customizing" into the address bar, I get a blank page. When I right click on the menubar and choose customize, nothing happens. I've tried all this in regular and safe modes. I've update firefox and java. I've checked all my updates and they seem good.
I'm running windows 10 and Firefox 42.0.
I've done a ton of searching on this subject. I've tried changing the windows theme. I can't find any add-ons that seem to be causing the problem.
PLEASE HELP!
{they want me to automatically add troubleshooting information but firefox blocks it from running.}

Did you try the Firefox SafeMode vs Windows Safe Mode?
Try Firefox Safe Mode to 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 that doesn't work, I am at loss as to what to suggest.
After the above,
Start your Computer in safe mode with networking. Then start Firefox. Try Safe web sites. Is the problem still there?

Tried all the above. Firefox in safe mode. Windows in safe mode - firefox normal. Windows in safe mode - firefox in safe mode. Nothing. about:customizing brings up a blank page. Right clicking the toolbar and choosing customize takes no action.

Experimental Features
Download Firefox For All languages And Systems {web link} Save the file. Then;
Using your file browser, open the Programs Folder on your computer.
Windows: C:\Program Files C:\Program Files (x86) Mac: Open the "Applications" folder. Linux: Check your user manual.
Look for, and rename any Mozilla or Firefox folders by adding .old to them.
After rebooting the computer, run a registry scanner. Then run the installer. If all goes well, remove the OLD folders when you are done.
Can you open the about:config page?
You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
Try to reset browser.uiCustomization.state via the right-click context menu to the default value.
Tried Fred's suggestion. Removed all Mozilla folders. Rebooted. Ran Ccleaner on the registry. Installed firefox from the link provided. No change.
cor-el: uiCustomization.state is set to default and has no value.
Thanks for hanging in there. This really sucks. I'm tired of IE.
Hm. That pref should have at least the default toolbar customization.
You can check for problems with preferences.
Delete possible user.js and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.
You can use this button to go to the current Firefox profile folder:
- Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
- http://kb.mozillazine.org/Profile_folder_-_Firefox
Create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":
- https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
- http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
