after updating to windows 10 firefox won't log in with facebook on webpage comments
Chrome is working just fine so this is not a fb issue, seems to be firefox only. When I go to the comment section of some sites and they only offer a facebook log in for commenting. I click the link, a screen pops up, and usually this allows you to choose facebook or sometimes disqus or the webpages own log in...this one only allows facebook.
I've turned off popup blocker, cookies are enabled, but the screen disappears before the log in option appears. This only happened after windows10 and only in firefox. It worked immediately before I installed w10.
Secondly, I can't upload the screenshot I took.

Hello,
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.
When you figure out what's causing your issues, please let us know. It might help others with the same problem.
