Firefox Support Forum

If I have any Firefox tabs open when I try to restart Windows, I get the "The following programs are preventing Windows from shutting down" error, with each of the FF tabs listed.

If I click Cancel and return to the desktop, Firefox is now in a bad state. It has minimized and cannot be restored; the tabs/window cannot be closed from the taskbar, etc. Usually I have to kill the FF process in the taskbar now.

This has happened for the past two years. Today I installed Win 10 Pro and it's still happening. Make this go away!

(Windows, always running the latest stable version of FF)

Every time I try to login to Capital One or Great Lakes or Nissan, Firefox blocks me and tells me "This Connection is Untrusted" It will not let me pay my bills. If this keeps happening, I will get another browsers. I have been using Firefox for years and this just started to happen.

Since I have installed Windows 10 Firefox crashes every time I use it. It will work for a short period of time and then suddenly crash. It also crashes ever time I close Firefox.

I'm getting a series of crashes of Firefox (I have the latest version) ever since I mistakenly "upgraded" to Windows 10. Windows 8.1 was working absolutely fine, what was I thinking??? Anyway, I'm getting crashes and then Firefox offers to restore where I was but then cannot do so. I followed the instructions on getting the Report ID

I recently downloaded the latest version of Firefox. I already had an account. I was able to login after the download for 1 day. Now when I try to log in it won't accept my username or password. I try to get it to email me a reset. It recognizes my email but I never receive the email.

Bought new HP laptop running Windows 8.1 - able to use FIrefox just fine as my default browser. Upgraded to WIndows 10 - I have installed/uninstalled/reinstalled Firefox several times, but it continues to crash every time I try to open a second tab.

I run multiple open tabs in Firefox in Windows 10 x64 with ATI video. When returning to computer after a few minutes, all windows are blank. I must close and re-open Firefox to see content.

I've been dealing with firefox "not responding issues" ever since I updated to your latest version (41.0) I no longer use it because it is just too frustrating! I have tried all your recommended solutions numerous times to no avail. I have also sent you feedback a number of times with no response. Not even an acknowledgement that you received my concerns. I will send my concerns one last time and won't attempt to use firefox again until I hear back from someone.

I installed the unity web player plugin ages ago, to play online games, but since earlier today, Firefox becomes unresponsive (or occasionally, Unity crashes) when trying to play those games. I never had this problem before. I have restarted my computer, I have tried opening firefox in safe mode, I have done a virus scan, and I've tried reinstalled both firefox and unity, and my problem still persists. I have no idea what I can do to fix the problem.

Hello, my problem is that if I use Facebook in some times i got screen(atachment). That problem is only in facebook. In Internet Explorer i dotn have that problem. I Use Windows 10 Pro 64bit. Grahpic Card Amd Radeon R9 280... Soo maybe its that problem? I m fresh from reinstal of system, all is new version of software. Thanks For replay ;)

The extension I use daily with Firefox is Lastpass. It and 9 others are 'disabled'! There is no choice to re enable them. They still work on my Windows 7 laptop so it is apparently a W10 problem.

Every time I try to access some web pages on Tumblr, using Firefox Developers Edition 43.0a2, it also occurs on the normal Firefox version, the tabs crashes after a few seconds, when staying on that page. One example is http://bovrilcat.tumblr.com/mywriting . I then tried loading the page on my Windows Phone 8.1 (Internet Explorer), and using data from my wireless carrier just in case if it was due to a problem with my home internet, and it worked perfectly. So, I tried to see on my laptop where this tab crashing is occurring if it happens on other browsers. Well, the problem does not occur on Microsoft Edge Browser/Internet Explorer on Windows 10, nor does the problem occur on Opera. I have had Firefox set as the default web browser ever since I bought the laptop. The same problem occurs at the college computer when using Firefox. Is this something to do with the browsers rendering platform?

Hi, i still want use mozilla firefox, but this shutdowns 3 times to 5 minutes is bad..

The problem is from Firefox 41, it suddenly stops working and then the crash report appears. It happens both with and without the addons enabled. It doesn't have a certain cause, it just happens.
