Firefox Support Forum

Firefox won't close. The icon is there on the Bar, but putting the arrow over the icon brings up the last page open, which won't close (using the X in the upper right corner), or open on the screen, (either by click or double-click).

Way too many crashes, odd window mashes, affects all open applications at times. Basically, Firefox is unusable after recent updates. On my laptop it also deleted all passwords - performed the guidance and it didn't work. After probably a decade or more I'm finalling going to leave Firefox to all of you - unless they can fix it by Friday 29th May.

Hi There, Please see the attached image. As you can see there are no menus to select in the top menu bar. When i scroll through they drop down but show nothing or partial info.

Can you help? Is this a software or hardwear issue? I do not have this problem with any other software on my mac.

I clicked on the Private Network icon when FF loaded, before I got the prompt to input my master password. After I input my master password FF crashed. After restarting FF, Now Private Network is asking me to "Login to FF account" when I click on the already dimmed Private network account. But, I'm already logged in. Also, When I enter my user/pass on the prompt to login again, I get a alert to check email and put the code in... That code never works(see attached screenshot). I get a red alert bar on the email code screen that there is a security issue.

So is there a timeout for such a issue? or ?

Ok so i made a master password for my account a while ago. And long story short i forgot it. So i went to the page where you can reset the master password and i did exactly what it told me but it keeps taking me back to the page giving me the link and instructions whenever i go to the link and press enter. Please help.

I can't upload any files on any website. For example, trying to share photos on Facebook – nothing happens. It's supposed to bring up the Finder menu and let me pick the file to upload.

I just switched over from Chrome and am on MacOS.

When I open Firefox, go to skribbl.io, and click "Play", GNOME crashes. The screen goes black with a little white cursor in the top-left and it recovers to the login page.

When I attempt to open Facebook I get:

An error occurred during a connection to www.facebook.com. This problem can sometimes be caused by disabling or refusing to accept cookies.

I'll be browsing a website, and with no rhyme or reason Firefox (on Windows PC) will decide that this website no longer exists and is no longer available, even the page I was on 2 minutes prior is no longer available (it even tried telling me that mozilla.org no longer existed). But the same site continues to work fine on the Firefox on my Android device.

The sites eventually "come back", but it's not very productive for a site to "disappear" in the middle of something.

So i've been having trouble starting fire fox after it updates. The last couple of times i just kept trying and it worked but this last time nothing seemed to solve the problem. So i old-school troubleshooted the problem by opening task manager, going to process' and selecting all users when trying to start fire fox. And i noticed another set of process's opening and closing with fire fox under the name LVPrcSrv except there was one more of these process's than there were of fire fox so as soon as fire fox and the additional LVPrcSrv process's closed i manually ended the last remaining LVPrcSrv process and then tried to start fire fox again and this time it work. I'm worried this trick wont work again so i'd like to ask the Mozilla developer whats actually wrong with my fire fox so i can fix it before it becomes permanently inoperable.

Sounds weird, but it sorta makes sense because while Firefox was hung up, I could open up Thunderbird but would get a message about a script (related to Chrome?) slowing the process down. Now, since the refresh, I can't open Thunderbird, and I get the message about XPCOM instead. I'm gonna need help walking through this....when I was in college, the computer sci majors were learning to program with keypunch.

I have been trying all day to access Facebook. I keep getting the following message:

Secure Connection Failed

An error occurred during a connection to www.facebook.com. The server uses key pinning (HPKP) but no trusted certificate chain could be constructed that matches the pinset. Key pinning violations cannot be overridden.

Error code: MOZILLA_PKIX_ERROR_KEY_PINNING_FAILURE

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

My main question is, has Facebook been notified of this problem? FYI, I have even tried (yuch) Chrome and Edge and get similar message. I will supply screen shot.

Hello,

I love Firefox. Thanks for making it and please keep up the good work. I used Firefox for years, switched to Chrome for about 10 and have now come back to Firefox again. Love the browser.tabs.unloadOnLowMemory config option. This was crucial to me returning to Firefox and I suggest you make this the default.

Anyway...

The issue I'm writing this for is that Firefox seems to be preventing my computer from sleeping. When I run

powercfg /requests

from a command prompt run as administrator, I get the following info: SYSTEM: [DRIVER] Realtek High Definition Audio (HDAUDIO\FUNC_01&VEN_10EC&DEV_0255&SUBSYS_10251259&REV_1000\5&26841d0a&0&00) An audio stream is currently in use. [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe [PROCESS] \Device\HarddiskVolume9\Program Files (x86)\Mozilla Firefox\firefox.exe

This seems to show Firefox running audio that is preventing the computer from sleeping. However, none of the tabs are currently playing any audio. Thought I'd report the issue here.

Please help as I am in the middle of an exam. Firefox browser freezes or unresponsive on MacBook 2019. I have installed and uninstalled several times to no vail.

Caution, I am not IT savvy and their website help is not helpful at all.

Urgent help

Dear support community,

I opened browser this morning, some kind of crash occured.. Then firefox reseted itself, created "old data" folder on desktop.

New profile was created and all of my data are gone (bookmarks, passes etc.) I have tried official solution to move "old" data into new profile folder, manualy import bookmarks backups, manualy import passes.. Nothing worked..

Any ideas how to get my data back?

Best regards,

Nasrat

I only get this error with Firefox, not other browsers. I tried to clear all history, cookies etc and disabled my extensions. Still got this error. It started after I updated Firefox to the last version.

I have a Raspberry Pi 4 running Raspbian (Buster). It has both Chromium and Firefox 68.8.0-ESR installed and has a Logitech C370 USB webcam.

Firefox cannot find either the camera or microphone on the webcam. I see only "Default Video Device" and "Default Audio Device" as choices when I try to select devices. The C370 cannot be located with the Raspbian version of Firefox.

Trying to use the webcam in https://meet.jit.si just results in a blank gray window. Trying to use the webcam in https://webcamtests.com results in a blank test window with solid cycling colors.

I have no problem using the C370 webcam using Chromium or using Firefox 71 under Ubuntu for Raspberry Pi, so I know that the hardware works fine and the Firefox could work too.

Does anyone know if I need to change any preference settings, etc under Firefox 68.8.0-ESR to make things work? Or is this a lost cause?
