I try to install Firefox on a HP Z1 G8 desktop under Windows 11 Pro. The first time I get a warning that a .dll is not available or so (I dont know what this warning is precisely, becaus it pops up for 2 seconds only ) , and firefox is not well installed, reinstalling goes without warning, but still Firefox starts and then stay dead, no sites, no settings. I know the security in this computer is very thight, but other apps install without problem and functions.

Why Firefox cant be installed where other apps can ??????

Hi, I can't install Firefox and I don't know what's going on here.

Yesterday I installed the latest version of Firefox and it worked fine. Then, I turned off the laptop and the next day when I was going to use Firefox, it didn't load any pages. Edge was working fine, Chrome was working fine, but Firefox was not working. Trying to fix the problem, I decided to uninstall Firefox and installing it again. In order to clean even more the previous installation, I even manually deleted the C:\Program Files\Mozilla Firefox folder to remove all possible traces. I restarted the laptop and downloaded again the Firefox installer. I don't know how, but the installer detected that I had already installed Firefox before. I unchecked restart Firefox and hit the button to continue with the installation. After this, was impossible to install Firefox again. I got a message saying that the installation cannot continue because the VCRUNTIME140_1.dll was not found. The message said that this problem can be fixed by reinstalling the program, but that is not true, everytime I try to reinstall it, I get again the VCRUNTIME140_1.dll error.

After this, the installation stops and the Firefox icon appears on the desktop, but it doesn't install properly the software and when I open it, I cannot browse the Internet.

Do you know what's going on here and how to solve this?

Cheers

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.

Brand new pc, new download of Firefox. App opens and allows web addresses to be entered but does not load anything. Nothing happens, it's a blank page. I can't access any settings pages either. I've downloaded and reinstalled Firefox a few times and I got an error message during installation two of the times. I've attached a screenshot of the error message, which reads "firefox.exe - System Error // The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem."

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.

I got a new PC and installed Firefox, synced with my account. Everything worked fine for a few days but then it became unresponsive, in the sense that it won't try to load any pages at all. I uninstalled it completely and did a refresh but it is still the same - attached is a screenshot of the brand new copy, where it won't even load the welcome info. Entering a URL and hitting Enter does nothing at all. It's totally unusable and I have no idea what else to try! Anyone have this issue?

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?

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?

PC was running fine and firefox. Removed the office365 app that comes with win10 and now its no go. Reinstalled and no go. Done safe mode and no go. Removed all files and new install of firefox still no go.

So I have to say that may be office365 app has removed some important files that were shared. I haven't installed office365 as I use office pro 2010 which still works fine. Im used that snarky edge browser at the moment.

Any ideas?

Hello, Something strange happened during a recent Firefox update, not sure if it was something I did, or computer related, but now Firefox does not function. The browser will open but will not load any websites. Also, settings page will not open. If Firefox browser is closed and reopened a message is shown stating "Firefox is already running but is not responding. The old Firefox process must be closed to open a new window".

My troubleshooting actions: Installed/Uninstalled firefox several times, removed c:\ProgramData\Modzilla folder - status/functionality mentioned above does not change.

Windows running on target computer is completely updated and patched.

Thanks for assist, David
