Pages will not load

This afternoon I downloaded a game from GoG. Since then, Firefox will not load any pages. I have reinstalled Firefox;when that didn't work I tried the refresh button, but that didn't work either. I have shut my laptop completely down and waited, then started it again, and I have just restarted it. None of this has made any difference.

I also uninstalled GoG.

How can I make Firefox work again?

Hi, is this on a Windows laptop?

Sometimes program installers and uninstallers mess with certain shared Microsoft files (you may see a message related to a missing VCRUNTIME140_1.DLL file). That can cripple Firefox, causing it play dead from the toolbar down.

To rule out that issue, you can (re)run Microsoft's installer for the VC Runtime files:

(A) Open https://docs.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-160#visual-studio-2015-2017-2019-and-2022

(B) In the "Visual Studio 2015, 2017, 2019, and 2022" section of the article, download the installer for your system:

  • 64-bit Windows: the "X64" download
  • 32-bit Windows: the "X86" download

(C) Run that installer and restart Windows.

Any improvement?

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

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