Issue began with an error message: firefox.exe - system Error ( The code execution cannot process because VCRUNTIME140_1.dll was not found.) ( Reinstalling the program may fix this problem. )

Although I have attempted the above action to reinstall the Firefox browser for windows 10, I was only able to get the browser to open with the menu bars, search bar, bookmark toolbar but webpage ACCESS would open. Even though I could type a URL into the search box, it would still not access or bring up any webpage and does not offer any error messages regarding this issue.

When I attempted to open the menu on the right-side of the browser to go into settings, I could click the button but it will not execute the action to open settings for me to access. Most of the other menu features also have minimal or no response actions for access either.

Please note that I am able to access and use other browsers for internet access, but would prefer to get my Firefox working again.

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.

I have uninstalled Malwarebytes and have applied the fix that you have suggested. After restart of my computer, I had reinstalled Firefox and have the same issue. This problem has not been resolved and would appreciate other possible fixes. Thank you in advanced for your efforts regarding this matter of concern.

Did you install Visual Studio?

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?

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

As a test, disable your protection programs.
