Firefox 技術支援討論區

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?

New (to me) machine (Win10) came with 30 day McAfee installed. Uninstalled and it killed Firefox. Gave a missing file message at first so reinstalled Firefox. Now, no message, but Firefox opens with basically blank window and unresponsive.

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 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

Good morning.

If I try to delete Mozilla VPN from my pc, using Programs and Features in Windows 10, it will make Firefox unable to operate. The question is, how to delete the vpn from computer without causing Firefox to crash.

Thank you.

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
