I have a fresh install of Firefox Version 75 64 bit on a Windows 7 machine. If I open a picture or other material copied from the web and saved to the machine, Firefox attempts to "download latest" even though I HAVE THE LATEST. I have never had a systemic problem with Firefox before. The computer was custom built hardware for Windows 8, but has 7 running on it. I plan to upgrade to Windows 10 but do not want to do so at present. Firefox runs fine except for this constant and annoying attempt to update which I have to abort.

Hi All, I have only recently installed Firefox for a specific purpose, have no plugins installed, just the basic program with about 3 bookmarks, that's it. Was all working OK until yesterday when it just wont boot. I have tried everything I can think of, so far:

Have tried removing (using app cleaner) and re installing - No joy

Tried going to profile manager through terminal - deleted and created profiles but still no joy

Tried deleting app again with app cleaner and reinstalling previous version - no go

Tried starting app in safe mode (shift key) - no go.

Looking for suggestions as I need to use Firefox for just 1 old website that seems to not work on anything else!

I'm running a Macbook pro Early 2015, Mojave 10.14.6

I've been experiencing too much crashes on Firefox 75.0, downloaded from Mozilla, not the one that comes with Linux. I'm running on debian9 on Qubes OS but I also experienced crashes on Ubuntu 19.

It happens mainly when I switch tabs. I'm asked to restart. I already submitted hundreads of crash reports, hope you guys are taking a look. However this have been happening since january I guess. And it's getting worse.

Sometimes the crash will happen again and again if I try to reload the tab. I have to close the tab and open it again so it won't crash.

Please help, I love firefox, don't want to use another browser.

Here are a few ones:

I opened Firefox this morning and used it for about half an hour. I can't remember why I closed it (or IF I closed it) but when I attempted to reopen I got a blank screen attempting to open my Yahoo homepage, but nothing happened. I force quit and attempted to reopen and nothing happened. I'm on a iMac and the icon on the deck just keeps bouncing. I haven't changed anything and it worked fine earlier. Is there a system problem? Thanks.

upgrade from 74 to 75 the browser won't go to any site. The lovely new big address bar shows up, but that's about it. Other browsers no problem.

So I generally keep Firefox up to date, letting the system manage itself, but this time I have had to disable this update. When I update, either through the automatic updates, or even from a fresh install of 75 (or beta 76) the browser starts, I see the lovely new address bar, albeit blank, and the browser just hangs right there. I can type in the nifty new bar, but nothing happens, no browsing to a site, no opening configs, nothing.

I have this issue on windows 7, 8 and 10 machines, so it's not an OS issue.

When an update does happen it chews up my profiles too and I have to end up rebuilding those. Only when I go back to 74 does Firefox work again.

I'm at a bit of a loss here.

I have downloaded the "latest version" of Firefox to my Mac which is running macOS Catalina Version 10.15.3. After 7-10 days Firefox will not "open". I then uninstall it, and reinstall it. Again it works for 7-10 days then will not open at all. I have gone through these install / uninstall processes at least 10 times. Yet after 7-10 days Firefox will not open. What is causing this, and how can I keep Firefox working continuously on my Mac? Thank You. WA

P.S. - I am sending this question from a Windows 10 computer because I cannot open Firefox on my Mac.

Hello, The day before Firefox just stopped working, I can start the program but its completely disfunctional. Menu bars roll down, but if I click on anything, nothing happens, like if the buttons were dead. External buttons like "open file", "save page" do pop up, but not internal ones, like Troubleshooting info, probably because they would also open as a Tab, which doesnt function. I can type into the search bar, shows the url, even seems to have access to search suggestion from Google, but nothing happens at all. I tried everything I could find, reset Firefox through safe mode (also doesnt work better), completely deleted and reinstalled everything, including all data folders, checked my Antivirus (Norton... yes, could be bad), but I even deinstalled antivirus. Also tried "netsh winsock reset" https://support.mozilla.org/en-US/questions/1021896 Im out of options. Thanks for Help!

How it happened: 1. I installed Anaconda(python3.7) and Visual Studio 2015 (to get the required C++ for TensorFlow) 2. Decided to uninstall Anaconda and Visual Studio 2015 and restarted which is when firefox gave the error vcruntime140_1. dll was not found. 3. I downloaded and installed vc_redist.x64 and restarted 4. Firefox does not give an error anymore but no websites appear (just bank screen). I can see the firefox dropdown tab for options, but clicking options does nothing


What I've tried: 1. Uninstalled firefox using an uninstaller that removes residual files 2. Re-installing firefox 3. Running firefox in safemode and clicking 'restore' as well as trying it in safemode


Chrome is working with no issues, but I prefer firefox.

As the question says. I updated my Mac (2018 MacBook Pro) to the most recent OS (Catalina), I've uninstalled and reinstalled Firefox like 6 times, cleared my trash and any and all Firefox files, and deleted all profiles, made a new default one, and then deleted that one when it still wouldn't start, and restarted my laptop more than once. I cannot seem to get it to start no matter what I do! I've tried every fix I can find online. Every time I try to launch Firefox, it appears in the dash for a second and immediately shuts down. Trying to start in Safe Mode doesn't work either. Firefox used to work, but then I force quit it *once* because I was quitting all applications I wasn't using. Now it won't work at all no matter what I do. How do I fix this?

I open task manager, and see that firefox is in there, and constantly opening and closing new processes on itself. I try to kill the process and cannot as whatever one I'm trying to close is already dead and a new one takes its place.

I was on nightly and today I guess my friendly IT admin pushed a system policy that blocked the firefox binary from updating itself. Since then, I have been stuck in this restart required loop.

No matter what version of firefox I launch, I get prompted to restart because firefox was updated in the background and it's basically stuck like that.

I have disabled the antivirus service completely, deleted my nightly installation, purged my regular installation through apt, installed nightly at a different path, deleted .mozilla etc.

I keep getting these errors when I launch firefox from any installation in a terminal:

Both Firefox and Chromium-based browsers are laggy (but in different ways) on Linux but not on Windows on the same computer. I have done GPU and CPU benchmark tests on my PC and they seem to perform better on Linux than on Windows.

I have tried different distros and I seem to be having the same issues. Both of these browsers have hardware acceleration enabled. I have tried booting into the LTS kernel as well, still the same issue persists. I have tried different DEs and I have even used Wayland instead of X11 and there doesn't seem to be a difference. I have an Intel Integrated HD graphcs card and my Laptop is a Dell Inspiron 2 in 1.
