Firefox Support Forum

its always crashing, disconnecting or going on unresponse, i want to know why its doing that and how i can stop it, and i cant use another browser, theyre even worse sometimes

Dear all,

I am having a severe issue using Firefox on Linux. That is when I use the browser to watch YouTube it is almost guaranteed that the entire system will hang, become unresponsive and then require a hard reset.

I'm using Xubuntu 19.04.

The laptop is a ThinkPad T450. It has a standard configuration except that I installed a SSD. I ran a comprehensive self-test using the Lenovo BIOS' testing feature and everything was given the all-clear. I note that the same problem doesn't occur on my preferred WebKit-derived browser which is Vivaldi.

I'm not the only owner of a T450 in my household. Curiously, this other T450 which runs Xubuntu 18.04 (LTS) does not manifest the same issue. This system also uses Firefox as its browser.

I was advised to check the system logfiles. The only mention of anything likely in the logfiles is the xsession-errors file:

(xfce4-panel:1291): xfce4-panel-CRITICAL **: 21:01:45.450: panel-window.c:2245 (panel_window_active_window_geometry_changed): expression 'WNCK_IS_WINDOW (active_window)' failed.

(/usr/lib/firefox/firefox:1631): dconf-WARNING **: 21:01:47.129: Unable to open /var/lib/snapd/desktop/dconf/profile/user: Permission denied [Child 1577, MediaDecoderStateMachine #1] WARNING: Decoder=7f15d3e94c00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::MozPromise<RefPtr&lt;mozilla::MediaTrackDemuxer::SamplesHolder&gt;, mozilla::MediaResult, true&gt; &gt; mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file /build/firefox-9JL5Vx/firefox-69.0+build2/dom/media/MediaDecoderStateMachine.cpp, line 3309 [Child 1577, MediaDecoderStateMachine #1] WARNING: Decoder=7f15d3e94c00 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::MozPromise<RefPtr&lt;mozilla::MediaTrackDemuxer::SamplesHolder&gt;, mozilla::MediaResult, true&gt; &gt; mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file /build/firefox-9JL5Vx/firefox-69.0+build2/dom/media/MediaDecoderStateMachine.cpp, line 3309 </p>

Reference to my post on the Ubuntu forums: https://ubuntuforums.org/showthread.php?t=2426276

I'd greatly value any help to solve this issue. I'm willing to look at other logfiles or send over any additional information that might help diagnose this problem. Anything to help me get back to using my browser of choice!

Kind regards. Thran

i have windows 7 64 bit machine and having firefox 36.0.1 and firebug , i did fresh installation 2/3 times but of now use.

here are the issues i am facing .

if i restart my machine firefox works for some time later its opened tab or newly open tabs keeps rolling nothing happens no site gets loaded ,even my web application (localhost) page doesn't open up if i close the firefox the page gets closed but firefox.exe keeps running which doesn't allow me to open new instance of firefox if i do so i get error message old process is already running and later comes your profile is missing or inaccessible i try to kill that process but nothing happens to it i did installation on other drive as well but nothing is working for me i created new profiles but that is also didn't work

i am really frustrated this is happening since last two days i can't work without firefox as i need it to debug my scripts using firebug

i have submitted crash report as well ... what should i do ???

I tried to delete browsing and web history when closing Firefox and this problem happened with Firefox immediately hanging up not closing except on 'force quit' and then totally not opening at all. It won't open in Safe Mode just zilch happening! Nothing I've tried has worked. I've removed and reinstalled Firefox, it but the same immediately happens. I am an older person and not a tech head! So need some simple instructions. Presently I am using Safari and but would like to get Firefox back and reinstalled again so I can access my book marks. Thanks for your help.

Hello, my problem is as follows:

I had a session open when i updated Firefox. It closed the browser however Firefox didn't show me any indication that it was updating so i tried open it again. Right that moment the update window showed up and somehow Firefox crashed. When i opened it again, my previous session was lost and i have no way of retrieving it. There is no option popping up in the menu that says 'Restore Session' and other methods that i have seen online are a bit difficult to understand.

Also the sessions i can recover are all after Firefox kinda crashed/Firefox updated so i don't know how to get my old session back. The session i want to recover is before i updated to Firefox 62.0 on the 10th, September. (Time stamp would be around 5:30pm CEST)

Oh and i have seen this thread (https://support.mozilla.org/en-US/questions/1204253) and i tried doing it, but the session i want back is not there.... does that mean worst case scenario happened and i won't be able to get my session back? ;____;

This may be a dumb question but would reseting my windows version to 9th, September help? I mean it would erase the update i did for Firefox and should (as much as i know <.<) also reset the setting for Firefox to yesterday's ones correct? But would that help since my problem is on the net surface and not a computer problem >.>

ps: i wanted to upload pictures but it somehow doesn't let me, so if you need them, please tell me and i will try to send them.

After many years of Firefox usage it has suddenly started crashing with the error as below (I've extracted the details from from Win 10). I've tried an installation from scratch i.e. no add-ons etc and still it crashes. Can you help. Many thanks, John Peart.

bp-e0b3fd64-4196-4da9-ba62-3e1c72150903 Browser restauration or new installation of the browser didn´t bring any change. I scanned for viruses (Avast, SuperAntiSpayware, Malwarebytes and Stinger) with no viruses found.

It started 4 days ago that some websites like www.reuters.com didn´t load. Also downloading a file only generates files with 0 Bytes. If he loads a website, then the load sign runs permanently. Today the browser can´t start any more. He only generates crash reports. After he asked me to restore the last session, a new crash reports appear.

Come and IE work. However I hate them and want my Firefox back. Please any hints to resolve this

Hi.

I am in windows 7 , 64-bit. Any version of Firefox which is higher then 39 - crashes.

Note - (I don't know if relevant) it's a work PC behind a corporate firewall, anti-virus and Web-Sense (which are not conrolled by me)

So I can't upgrade. I had to un-install Firefox after upgrade, re-install 39, and disable automatic upgrade.

I have tried also the Portable app of - in latest Firefox version (42) - and it crashes too.

I'm attaching the Crash Report text:

I have been watching Netflixs on my PC with no issues. Last night every time I tried to open Netflix the tab would crash. I have a secure internet connection and visited several other sites with no problem. I checked and made sure Netlflix has Firewall access, I have cleared my cache/history and add-ons. I have re-started, opened in safe mode, updated and nothing works. The error says "GAH. Your tab just crashed. I have checked the "Send automated crash report along with URL's" boxes. Even doing a google search for Netflix and clicking on the link there gets me to a home page but the minute I try to sign in to Netflix or a program it crashes again. Please advise and thank you in advance.

Tried 3 times to import bookmarks but Firefox crashes when it gets to 'bookmarks' after copying cookies and browsing history from the 'items to import' window. Checked all the Chrome bookmarks for errors etc, cleaned them and then tried again but still crashing. It is only Firefox that crashes everything else works OK.

Both firefox and thunderbird crash directly to the "Mozilla Crash Reporter" on startup. This also happens in safe mode.

So far I re-installed firefox through the package management (first completely removed it including configuration files, then installed it again). The profile created by the re-install is still completely empty, there is no data from the original profile and no plugins.

The button to automatically add troubleshooting information doesn't work for me (probably because I'm using chrome now), so I'll try to add relevant information. If anything is missing, please ask.

Firefox keeps randomly crashing. Here are the last four crash reports. My computer is up to date, but I am running Firefox 28.

I had many tabs open at once in only one window. My disk came to 0 bytes of free space and the browser closed suddenly after some time. Even before freeing up space, I could reopen it and even restore my session. After deleting the folder /var/cache and restarting the OS, Firefox just wouldn't open, it just crashes, offer the option to quit or restart but clicking restart just makes the Mozilla Crash Reporter to open again.

Don't know if it's of any help, but trying to open it through the terminal (with or without -safe-mode) the following lines are shown: ExceptionHandler::GenerateDump cloned child 7950 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal...

After a major windows 10 update, Thunderbird and Firefox crash continuously, usually the moment I open another program, rarely when using Thunderbird and Firefox. Reinstalled Firefox, but it still crases. These two are the only to have problems after update. Do you have a solution? Thank you and good day, Luciano

As to question, yesterday Windows did a hughe update and after that firefox keeps crashing (not so chrome or edge, but i'm convinced firefox user, I don't want to abandon). How may I solve that issue? Thanks for every piece of advice and help.

Firefox crashes often, like four or five times a day. If crash frequency seems to be decreasing, it's just because I switch to Safari or Opera. I miss firefox a lot. I assume that you have access to crash reports. The only add-ons active are OpenH264 Video Codec and Shockwave Flash 10.0.r0. Many other add-ons are there, but are "never activate". Extension Dashlane is disabled. I don't seem to be doing anything unusual when it crashes. I also have an MBA with identical software, but Firefox is stable.
