Yesterday I was using the firefox browser normally and suddenly it stopped working. Now it does not load any websites (see picture). Also, to access the preferences tab if I do it by clicking on the menu, sometimes it opens up just fine but others it does not react. Same if I type in about:preferences.

I have tried the following:

- Refreshing firefox - Using firefox in private mode - Deleting all extensions - Using default system theme - Selecting no proxy in the network settings - Reinstalling firefox - Clearing recent history - Setting network.dns.disableIPv6 and network.dns.disablePrefetch to True

Nothing is working... I have looked everywhere for a solution, please help!!

You can check for issues caused by a corrupted or incomplete Visual C++ installation that is missing runtime components (Redistributable Packages) required by Firefox, especially VCRUNTIME140_1.dll.

Install both 32-bit and 64-bit "Visual Studio 2015, 2017 and 2019" downloads, (x86: vc_redist.x86.exe and x64: vc_redist.x64.exe) from https://support.microsoft.com/help/2977003/the-latest-supported-visual-c-downloads

You may not need the latter (32-bit version) if you use 64-bit Firefox. You may have to reboot the computer. ++++++++++++++++++++++++++++++++++++++++++++++ In another thread, a user reported that a recent update of Malwarebytes Anti-Exploit (version 415) may be causing symptoms similar to the VC Runtime problem. If you have MBAE, it should have a setting to exempt Firefox. You could test whether that makes any difference.

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Hi, I tried both options. The first one did not work and for the second one, I'm unable to enter the profiles tab. I write about:profiles in the address bar, click enter and it does not take me anywhere.
