I-Firefox Isithangami Sokwesekwa

Firefox (and chrome, but not edge) crashes on startup. There's no crash report. The window shows up as an outline for a fraction of a second and then is gone. It doesn't show up in task manager. I've uninstalled and reinstalled multiple times. I've updated windows and my antivirus. I've tried a few other fixes that came up from searching for a fix, but so far nothing has helped.

FIX what seem to be CLEAR conflicts with relationship between platform and user's device (desktop, Dell Optiplex 790 in my case - that do NOT occur with Opera, otherwise) as WELL as aforementioned ATROCIOUS performance quality - BTW, this is the SECOND update / upgrade I've done in LESS than a WEEK.....

This post is on my Mac Catalina. This morning Firefox updated on my Windows 7 before I closed out. Now that it is evening Firefox does not open on that computer. What should I do to fix it since it does not open; it crashes immediately.

[Update: This works correctly with HTTP/2 disabled, so it is somehow HTTP/2 related. Firefox's partner is terminated with ATS 8.0.2, so this is most likely an interaction with Traffic Server, but debugging help is still needed.]

I recently upgraded from Mediawiki 1.31 to 1.35 on Debian 10. Since this upgrade, attempts to log in with Firefox are impossible -- Safari and Chrome work fine. Firefox 96.0 displays the attached error "Secure Connection Failed" but no security error is provided. This seems to be a defect in Firefox, but I am having difficulty diagnosing further.

Looking at both server trace logs as well as the Firefox debugging tools, I see Firefox does an expected POST request to the login page:

 POST https://newwiki.convivian.com/mediawiki/index.php?title=Special:UserLogin&returnto=Main Page

The MediaWiki server replies with a 302 Found and redirect to the Main Page on successful login, but Firefox considers this response insecure on some way that is not indicated. The "Security" tab in DevTools shows no security errors on the transaction.

I am able to reproduce this on multiple machines running Firefox 96.0, as well as with Troubleshooting Mode enabled. No errors occur with other tested browsers.

Is there a way to extract further debugging information from the browser?

Since I upgraded to v96.0 I have been getting this error message every time I open Firefox. I read another thread that suggested I alter...

    browser.sessionstore.max_resumed_crashes

...to zero (0) in "about:config". However, I'm guessing this change basically turns off this functionality, which I wouldn't want if the browser actually crashed. However, this doesn't seem to work at all, either on the network "Data" folder or the local "Data" folder, so Firefox has become very annoying to use.  :-(

I have two (2) data directories (which, of course, contains my profile) for firefox; one on my local machine and one on the network. I normally use the network data directory and only use the local one if I'm traveling. I haven't used the local "Data" for three (3) months, and it worked fine for two weeks. As a test I activated the local "Data" directory (I renamed "Data" to "Data_network" and "Data_local" to "Data"). I got the same problem so I'm sure this has to do with the latest upgrade to v96.0.

My settings, which have always been set like this, are:

 + I have "Open previous windows and tabs" un-checked.
 + I have "Choose what you see when you open your homepage, new windows, and new tabs." set to "Custom URLs..." and my "Homepage and new windows" is set to my home page URL.

Any thoughts?

This started two days ago. I did not recognize what was happening, but the computer slowed to a point of complete unresponsiveness. I had to hold the power button in for a hard shutdown. Next day, I was watching a YouTube video, the video stopped playing, and the computer slowed to a snail's pace. Task Manager revealed something was using up ALL system memory. A look at running processes showed that the culprit was Firefox.

Firefox would start normally, then gobble up all system memory over a few minutes, rendering the computer almost inoperable.

Tried garbage collection, CC, and minimize memory usage under about:memory. This would temporarily reduce overhead, but then it would climb back up next time I started Firefox.

The Ant Video Downloader underwent a redesign days ago; this memory issue started exactly two days ago, on Friday evening, the 7th of January, 2022.

I disabled the add-on. At this moment, Firefox memory use is 642,716 KB of an available 12 GB. There seems to be one main process using the largest share of memory (200-300,000 KB) with 12 other firefox.exe processes running concurrently, all using smaller amounts of system memory. Firefox memory use no longer climbs until all system memory is consumed.

Is there any way to rein in memory use by Firefox add-ons short of disabling them? Are other users reporting this issue? How are add-ons vetted prior to use with the browser? There are few of these video downloaders available. Most are merely copies of a single piece of non-functioning software—but listed under different names, supported by what are clearly fake reviews. Is anyone verifying the integrity of these add-ons in addition to their developers?

In this case, the developer is based in Hong Kong.

Thank you to the community for any assistance offered in this case.

Just out of the blue my browser stopped loading pages. I went through all the processes recommended here and none worked. With the browser open now, its using a high amount of CPU and the power usage is Very High. Nothing is open because it won't load anything. No error messages, just stuck with the little dot going side to side. I used chrome to download and install an update, but still nothing.

Help :(

When typing, for example an email in office 365 webmail, approx 1 in 10 characters is missed. This happens in every session and after reboots. It doesn't seem to matter if i am typing slowly or quickly, and it happens in an incognito browser window too. I am certain that key-presses are being sent, they are just not reflected reliably in the browser. There are more than enough resources available for firefox.

A few days ago there was a Firefox update and this morning suddenly GeckoMain started (out of nowhere) using the CPU at 80% (which lead to the CPU fan going nuts). I opened the gnome system monitor and it showed that GeckoMain was overusing the CPU. There's also a process running called "Privileged Content". For as long as this additional process is running, Firefox is behaving as if there were no internet access - infinite time to load any page and if left undisturbed, after a while Firefox closes with a crash message. Also, for as long as this problem is happening, simply closing Firefox with the X button doesn't close it - GeckoMain is still running and the only way to actually close the browser is "killall GeckoMain". So I removed all extensions one by one in order to make sure it's not an extension causing this. It's not. Even after removing all extensions the problem continued which lead me to believe something in my prefs.js is causing it. There were so many things modified in about:config over the years that I have no idea which one might be causing the problem. I have uploaded the prefs.js file here, so that you can review it, if needed: https://drive.google.com/file/d/1j-EAaeBrcawRfzrIr4n9Pg6IyvM9zROV/view?usp=sharing

At the moment I'm writing this question through Waterfox bc Firefox is unuseable with this problem.

Most of the others topics apply here.You override preferences and other serivices to install updates I don't want or need and more -- Firefox now wants ALL of your personal information, which iif you don't comply, creates conflicts with every other program. I just bought this lapper a year ago and already had to reinstall WIn 10 twice. I am one inch away from going with Google Chrome, which is just as bad but at least doesn't conflict with Windows, which is equally as invasive and worthless. I'm not a brain surgeon able to digest your "tools" in developer-ese. Help!

When a push notification is received, the display turns on (via DPMS). Is it possible to get rid of this behavior? Is there some configuration option in Firefox in about:config? I can't exclude that it's not Firefox doing this, but I'm guessing it is.

The browser revs up my memory and doesn't connect to the internet until finally it crashes.

I'm on windows 11

Please advise

Best regards Sune

Hello For past 2 days when I try to download from any website the save as dialog appears but then it crashes firefox and I have to close firefox. I am running version 96.01 on Windows 10. Latest Nightly also installed and this problem is not on the nightly.

I'm having problems with playing some videos on youtube, facebook etc. For example in youtube the video never stop to load and after some minutes the following message appears :"if playback doesn't begin shortly try restarting your device". In other browser such as edge and Chrome the video works without problem. I have the last version, 96.0.1, 64 bit edition. I'm using a Dell Laptop, with Windows 11 Pro version 21H2 OS Build 22000.434.

I already done the following steps but the problem still exist:

-Update Firefox -Turn Off Hardware Acceleration -Disable Firefox Extensions -Delete Browser Cache and Cookies -Allow Autoplay on Firefox -Allow Cookies, History, and Pop-ups -Refresh Firefox -upgrade graphics driver -unistall and reinstall firefox -create a new firefox profile

How can I solve the problem?

Best Regards

We are using a Citrix server and have Firefox installed for browsing (normal auto-updated version, not ESR). Some user experience a problem with a normal Google search or a search in Google Maps. It can also be reproduced by executing multiple searches in Google Search/Maps in a row. After 5-6 attempts, the response is hanging for around 3 minutes before it continues. I've added a console export in the troubleshooting information.

It seems that the issue is not appearing when activating the troubleshooting mode. But there are no add-ons (extensions and themes) activated (expect the 2 default plugins) and turning off hardware acceleration doesn't help too. It seems to be related with another setting which is disabled in the troubleshooting mode.

We have also deleted/recreated the Firefox profile and the complete Windows userprofile.

Have someone an idea what we can test/try to identify/solve this issue?

Message: Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

Windows 11 version 21H2, build 22000.434

About a month ago, I started having a problem where all pages on YouTube randomly stop loading. It does this with no rhyme or reason and usually for around a minute at a time. It just hangs until it abruptly starts working again. Occasionally (like if I try to log out while this is happening), it will give me an error saying I'm "offline", even though I am most definitely not offline. During this time, all other websites (Google, Wikipedia, Hulu, etc) work fine, so I know it's not my Internet. Other than that, it doesn't give me any errors.

I am using a MSI laptop on Windows 10. Oddly enough, YouTube loads properly in incognito mode and in Windows Edge, but clearing my cache and cookies, disabling my extensions, and updating Firefox to the latest version didn't solve the problem. I even enabled each of my extensions separately in incognito mode while YouTube wasn't loading in a normal window, and each time YouTube loaded properly in the private window while simultaneously not loading in the normal one, so I know none of my extensions are causing the problem. Restarting my computer also didn't do anything. This problem persists when logged in or out of YouTube, no matter the account.

I reported this issue to YouTube back on December 29, but it hasn't been fixed. I also made a post on the YouTube Community a few days ago, but I didn't get any helpful answers. Any help would be appreciated!

I have a problem with running Firefox v95.0.1 on Ubuntu 20.04 operating system. When I first open Firefox, process with command /usr/lib/firefox/firefox -new-window starts and taking up 100% CPU. This process doesn't stop even if after closing Firefox and after a while crash reporters says that Firefox is crashed. While the browser is open and the mentioned process is running, I can't open any web page, since it's loading infinitely. I attached here screenshots of both process details and crash reporter.

My Firefox updated to 96.0 yesterday. Since then it freezes frequently apparently checking for updates; no pages load during the freeze. After some time it decides it is up to date and Firefox starts working again, only to start checking for updates again after a few minutes and freezing again. A second installation on a laptop (also Windows 10) is behaving exactly the same. How do I resolve this? Thank you.
