49.0.2 Firefox works fine, but I can't upgrade to Firefox 50: the new version does not and will not be closed.

In early October, Microsoft forced an upgrade on my computer from Windows 7 to Windows 10. Firefox 49.0.2 continued to operate correctly. Then Firefox 50 arrived, and when the automatic upgrade occurred, Firefox would no longer work. It seems normal on the screen, but it will not look for the website of my saved favorites, and it connects to sites that I identify by entering the url in the address bar. It also doesn't close - to close Firefox, I have to call the Task Manager. I tried to uninstall Firefox 50 and put it back - that does not work. I also tried to uninstall Firefox 49.0.2 completely, restart the computer and then do a fresh install of Firefox 50, but nothing seems to work.

I came back to Firefox 49.0.2 as a temporary measure (disabling the auto update feature), but this isn't a good solution in the long term. What should I do? Wait for Firefox 51? Abandon Firefox?

Help!

If you want to revert to Windows 7, you can.

Your problem may have several causes. Let's start with;

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but it no longer recognizes your updated as version being approved. Now how do I solve the problem: to allow Firefox to connect to the Internet again.

  • Make sure your Internet security software is up-to-date (for example, you are using the latest version).
  • Delete Firefox to list your program of programs approved or recognized. For detailed instructions, see

Configure the firewall so that Firefox can access the Internet. {web link}
