A routine update from Firefox version 99 to version 100 caused Firefox to quit loading web pages, including the Settings page. Firefox appears to load normally but will not display any web page. The only thing that works consistently is Help/About Firefox. System: Lenovo E495 (AMD Ryzen 5 3500U) running Windows 10 Pro 21H2, build 19044.1706 Symptoms:

• Version 100 and higher work correctly in trouble-shooting (safe) mode
• Refresh does not resolve the problem
• Manually removing extensions (NoScript and Cookie AutoDelete) does not resolve the problem
• Uninstalling Firefox and existing profiles (all Mozilla folders in AppData/*), then making a clean install of version 100 does not resolve the problem
• Removing version 100 and reinstalling version 99.0.1 restores normal operation (repeatable with higher versions)
• Updating from version 99.0.1 to version 100.0.2 or version 101.0 does not resolve the problem
• I have not tried removing any Mozilla registry keys

Firefox always uses excessive GPU memory when I watch video and livestream. about:memory shows that the explict GPU memory allocation is only about 200 MB but in the task manager the GPU memory usage is 1GB, and the latter doesn't decrease even if I close the tab. I suspect that this is a memory leak. I searched for Bugzilla and found a similar issue that has been existing for years: https://bugzilla.mozilla.org/show_bug.cgi?id=1386177

Every time i open Firefox a little window comes up and says for a fraction of a second that im using an older version of Firefox (Even though that i'm using the latest) and then it crashes. I've tried everything, from reinstalling, rebooting, making exceptions in the firewall and even manually installing Firefox, but nothing. Before anyone asks, i do not have AVG, Avast or Commodo, and the Firewall is the basic Windows one. The issue is very similar to this one:https://support.mozilla.org/en-US/questions/970099. I also tried what they said, but unfortunately nothing woks for me.

Hi, can you help? I can't access morphy richards website from my phone and my pc through Firefox. I can access it through Microsoft Edge on my pc and my Samsung Internet app on my phone but not through my Firefox app or windows 11 Pro desktop pc. I get this message on my pc

Hmm. We’re having trouble finding that site. We can’t connect to the server at www.morphyrichards.com. If you entered the right address, you can: Try again later Check your network connection Check that Firefox has permission to access the web you might be connected but behind a firewall

and this message on my phone through the Firefox app

Address Not Found. The browser could not find the host server for the provided address. Check the address for typing errors such as ww.example.com instead of www.example.com.

If you are unable to load any pages, check your device’s data or Wi-Fi connection. 

Steps I have taken is clearing data, history and cache on pc, turning off mcafee firewall. I use my pc through a wired Internet connection and my phone through Wi-Fi and data and it's the same on both I can't access the website. Like I mentioned I can access it no problems through Microsoft Edge on my pc and Samsung Internet app on my phone so I have now pinpointed it to Mozilla Firefox being the issue, also this is the only website I have issues with. Please can you help? Regards, Steve

Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

The tab keeps crashing:

bp-6ab50b7b-01af-46cd-a55d-313f70221019

Tried new install, troubleshoot mode and deleting cache. Issue persists. What else can I do?

On one web site (see attachments), my location is being detected as being outside USA while using firefox desktop browser, yet on the same computer, my location is being correctly detected as being inside USA.

You will see the asian words. When I change the pull dawn tab ("Saudi Arabia") to "USA", the asian lettering does not convert to English.

Not sure how to fix this.

I can log into GMail via our SSO just fine, however after a few minutes I see the "error connecting for X-minutes" bar. I try to force refresh the site and every time I get the bellow error. This is also happening when I am using Firefox Troubleshooting mode, to see if maybe it's a plugin/extension causing this issue, but it's not.

Secure Connection Failed

Firefox displays websites with gibberish for headlines. I've monkeyed with the "Fonts" preferences in the Settings to no avail. Perhaps I'm not choosing correctly. They are currently set with Firefox's defaults and the box allowing websites to choose their own fonts is also selected. No matter what I've done, it looks like the attached image. Help!

Firefox crashes whenever I use ctrl v or right click, and pulls up a window that it crashed. Whenever I start it back up, it says it wasn't able to restore session, then restores it anyway after I press to restore it. Another thing is whenever I try and upload a file onto a site it crashes as well. I'm on Mac OS x 13 and reinstalling firefox hasn't fixed it. This is relatively sudden, it happened about around 3 days ago for the first time, and at the same time I noticed it happening certain sites also started giving me '502 Bad Gateway' errors. Does anyone know what's happening and how to fix it? Thanks in advance!

Firefox crashes whenever I paste something in search bar. Even if its one word only. It has been like 3 months now and no help. It even crashes in troubleshooting mode. I have reinstalled and refreshed, but it helped only for a day.

Thanks in advance.

I'm using the latest version of Firefox on an updated Fedora Linux installation. I am experiencing for a while now random crashing while watching videos. The playback crashing is random, so I could be watching 5 videos one after another with no crashing and then one video will cause it to crash. The video causing is site agnostic, so it could crash from any site, not just YouTube. I saw in bugzilla something that I thought was related to the crashing (https://bugzilla.mozilla.org/show_bug.cgi?id=1779558) but it got resolved and it still keeps happening to me.

It's getting tiresome, please. What do I need to send you to help me fix this problem?

From today 4 march when I try to record a voice message on chat from facebook appear an error saying an error as occurred. On Chrome it work, from facebook app it work

I even tried other facebook ids and firefox profiles and ever the same. Even disabled the anti popup ublock

In all case I haven't added any conf or adon or other inside firefox, I use same conf as ever and from many years.

Today messages from microphone in chat does not work and facebook say an error occurred Is written in italian but say what I said

when I view a stock quote in Google Finance If I move my Windows cursor into the price chart and move the chart cursor to a new date or time the tab will hang. I can no longer move the chart cursor. Reloading the tab will no longer work. I have to delete the tab and then use History to reload it. There is no problem as long as I keep the Windows cursor out of the stock chart area.

I have several tabs with stock data from Google Finance open at the same time. For example. https://www.google.com/finance/quote/TSLA:NASDAQ https://www.google.com/finance/quote/AAPL:NASDAQ https://www.google.com/finance/quote/MSFT:NASDAQ

I am running Windows 11 up to date and Firefox 116.02. This has been a problem for a long time.

My community association uses Constant Contact for its documents, notices, etc. When I get an email message from them, it often contains several links beginning with https://r20.rs6.net. When I try to access one of those links, Firefox tells me "Hmm. We’re having trouble finding that site. We can’t connect to the server at r20.rs6.net." Chrome and Edge do not give the same error - they can access the requested page. Is there some setting in Firefox that I need to change to fix this problem? Firefox has been my default browser for years, but I also like to read notices from my community association.

Hi everyone,

Up until the latest FF release, opening an .ics (calendar file) link defaulted to the OS's preferred application; in my case Outlook. Now, every time I click on an .ics link FF asks where I want to save the file. I schedule ZOOM meetings all day and heavily rely on this feature.

I tried looking in FF's Files and Applications section in settings and .ics is not even listed as a file extension. I don't know how to add it.

Any assistance is greatly appreciated.

Jose

I am getting repeated pop-up windows that say that Firefox has crashed, but Firefox is not running on my system. It is not in the Startups and I rarely use it.

Windows 10 Firefox v110.0

Is this malicious not related to Firefox? Does Firefox have a background task that is not visible on Task Manager? Or what?

This report also contains technical information about the state of the application when it crashed.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.

Firefox has recently (within about a week or so) begun to crash randomly for me when switching between open tabs. The problem can be reliably replicated with ~6 tabs open, while quickly cycling between them. Firefox has been updated, and the crash still occurs even in troubleshooting mode. The most recent reported crash is Crash ID: 54793083-0841-470c-ae8a-687030240105. The flagged 'Crash Reason' is EXCEPTION_ACCESS_VIOLATION_WRITE
