I have very much came to depend on Firefox. I've tried everything mentioned to users with same problem. Even Passwords and Settings have white windows (no text or anything else showing. When I reinstall Firefox I get vcruntime140_1.dll error. How can I fix it? I have the latest update.

While writing this I went back to double check the vcruntime140_1.dll install. I found it wasn't on the main Mozilla Directory - so I copied it. And now Firefox works! The file came from https://www.dll-files.com/. I don't need any further assistance.

Just leaving this as a record for others who may be having a hard time.

Thanks Mozilla for all you do!

I am unable to open my Firefox on my computer because I receive a message saying that my computer cannot find the following file: vcruntime140_1.dll. I have tried uninstalling Firefox, and the reinstalling Firefox. This did not solve the missing file problem. I have tried re-installing Firefox. This did not solve the problem. The file is still missing. When I click on my Firefox App, all I get is a blank screen. I am unable to use Firefox. This computer uses Windows 10 with a 64 bit. I have several other computers, with Firefox installed, and I do not have this problem on any other computers using either Windows 10, Windows XP, or with a recent version of Linux. What procedure can I follow to restore this missing file to this computer? Your help would be greatly appreciated. I have some knowledge of computers, but I lack technical knowledge. Any help you can give will be deeply appreciated. Thank you

Recently I have been unable to surf the web on my Firefox Browser. I have tried uninstalling and reinstalling it a few time to no avail. I have checked my Firewall settings and Firefox is not blocked. I know other browsers work as I am sending this through Edge.

I checked my event viewer and found that Firefox was being denied access (see attached pic). Any suggestions to get this resolved would be welcome.

Firefox stopped working. I have uninstalled and downloaded numerous times. It still doesn't work. In the new install I get a warning box telling me that vcruntime140_1.dll is not functioning or something. Another item: A box tells me to turn off Firefox -- after I have uninstalled Firefox. The program opens and remains totally inert. I spent hours last night and finally it worked -- wonderful. This morning nothing worked. Uninstall -- install ad nauseum. Nothing works. I am writing you.

About a month ago, Firefox stopped loading web pages on my Windows 10 Lenovo Flex 14-IWL computer. The UI loads without any issues. However, no pages can be loaded, including Firefox's own pages like "about:preferences" or "about:performance." I completely removed all traces of Firefox from the computer twice (using Revo Uninstaller's advanced mode), but the problem remained after each reinstallation attempt. On the second of those reinstall attempts, I checked the Console after trying to load one of those control pages and found the error messages shown in the attached screenshot. What is happening, and how can I get Firefox working again?

(Note: Since I have completely uninstalled Firefox again since taking this screenshot, there is no troubleshooting data to send.)

I have no got a clue of what is my problem, it has always worked fine, yesterday I did get a request for firefox to update my security, I do not think I change anything, it all looked basic ok to me. But I did delete some unused programs in hopes of improving my empty space on the hard drive

I added the Mozilla VPN but that wouldn't communicate with my printer. So out of frustration, I uninstalled firefox all together. I then went to the mozilla site (on Edge) and downloaded the app. It completed the installation but when the browser opens it doesn't do anything. I can't move around or open any sites. It's just frozen on New Tab and nothing works. I can't even sign in - I can click on the sign in button but it doesn't do anything.

When I tried downloading the app from chrome, I got the attached text box and the same general result. Firefox opened but didn't work.

I've spent hours today trying to just get the regular browser working (forget about the VPN) and I'm frustrated. I have yet to find a way to call a support desk who can help me in "real time".

Thank you to anyone who can solve this for me and get me back to working in Firefox again (and able to print). Katie

I have been using Firefox for years but in the last 2 weeks it suddenly started not working properly, being incredibly slow with any search. I uninstalled and re-installed but it still would not work and not it will not even install properly. I have tried about 12 times to install Firefox but it never uploads and works.

I use Windows 11 on Lenovo Yoga, and use the 32 bit version of Firefox. Any ideas what the problem could be?

I was getting an unspecified bug with Mozilla VPN that wouldn't let me launch it, update it, or sign out of it. I decided to uninstall and reinstall it. Uninstalling the VPN required me to close out of Firefox. I did so. When I relaunched it after the uninstall so I could go download the new VPN files, Firefox was still displaying the tab titles but nothing else, not even the urls of the pages. The entire browser was completely blank except for the tabs. No other pages are accessible either. I tried restarting the computer. It didn't work. I tried uninstalling Firefox, restarting the computer, and reinstalling Firefox. It didn't work. I tried a clean reinstall where I deleted every scrap of leftover data I could find. It didn't work. I got a VCRUNTIME140_1.DLL error during an install attempt, which I attempted to fix by updating Visual Studio as outlined here https://support.mozilla.org/en-US/questions/1352013 and that didn't fix it either.

Hi everyone. For the last 6 months, the <Firefox.exe> process is being terminated immediately after launching it.

I tried every solution I came across in the internet: from making a fresh clean installation to changing the profile, deleting the cache files and searching for Malwares and viruses. Unfortunately, nothing has worked.

Nevertheless, if I rename the "Firefox.exe" file to any other name, it will work without a problem. And if I kill the <explorer.exe> process, and then run "Frefox.exe" -without changing its name-, it will also function properly.

Before yesterday, I bought a new computer, installed Firefox, and it was working smoothly. However, today, I installed Office 2021 Pro Plus, logged into my Microsoft account from Word and <Firefox.exe> process is being terminated upon lunching it again.

I formatted the system, made a restore point, downloaded another version of office (2019 Pro Plus), logged into my Microsoft account, and the same has happened again. I tried different scenarios; the result is always the same.

  • Same problem is happening with Chrome. Only Edge is working if I logged into my Microsoft account from office apps.

Any idea?
