Does Firefox draw its toolbars or just seem to freeze up?

Will Firefox start more normally in its Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled (to activate this "blind" press the key sequence: Alt h r Enter)

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?

You also could try to launch the troubleshooting information page from the Run dialog: hold down the Windows key and tap the R key (or find it on the menu/start screen), then type or paste the following and press Enter to run it:

firefox.exe "about:support"

The issue still alludes me. Firefox dose appear to be running. I can type in web address but the page is not displayed and there are no error messages. I'm uploading a screen shoot and troubleshooting info from running the command prompt that was suggested.

Hope this additional information gets us point to a solution.

The same blank page appears in Firefox's Safe Mode?

The OMTC indicates that your Firefox is using "off main thread composition." That is the default, but creates odd display issues on some systems. If you want to experiment with disabling it:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste layers and pause while the list is filtered

(3) Double-click the layers.offmainthreadcomposition.enabled preference to switch it from true to false

Any difference?

Issue still the same even after turning off layers.

Experimental Features

Issue unchanged.

I was assuming this was a display problem, but perhaps it runs deeper. The following thread has a procedure to reset some of the Windows 10 network plumbing that might be necessary in some cases: After upgrade to window 10, cannot access internet from firefox or chrome. Does that make any difference?

After complete reset of the TCP stack, Firefox was completely working again.

In short I ran the fallowing from start menu: cmd (ctrl+shift+enter) to run it as admin, then each of these command lines, if after running the commands, system ask to be restarted to complete, do so.

ipconfig /flushdns ipconfig /registerdns ipconfig /release ipconfig /renew NETSH winsock reset catalog NETSH int ipv4 reset reset.log NETSH int ipv6 reset reset.log

Thank for your help jscher2000.
