I GOT TIRED OF FREQUENT FIREFOX CRASHES (C0000005) IN BOTH THE 64-BIT AND 32-BIT DESKTOP VERSIONS. I HAVE BEEN USING THE 64-BIT VERSION IN WINDOWS 11 (I HAVE A HIGH-END SAGER LAPTOP WITH 32GB RAM. I INSTALLED THE FREQUENT FIREFOX UPDATES BUT THE PROBLEN PERSISTED EVER SINCE VERSIONS 42X WERE RELEASED. I TRIED THE 32-BIT VERSION BUT THE PROBLEM PERSISTED. FINALLED, I TRIED THE DEVELOPER VERSION: NO MORE CRASHES! I READ THE RESPONSES FROM YOUR CLUELESS STAFF TO OTHER CUSTOMERS WITH THE SAME TROUBLE. THIS IS NOT A WINDOWS ERROR; THIS IS A FIREFOX APPLICATION ERROR. MAYBE SOME OF YOUR FIREFOX DEVELOPER CODERS SHOULD ASSIST THE 32-BIT AND 64-BIT DEVELOPERS. OR, DUMP THE VERSION 4X CODE AND BUILD ON THE MORE STABLE 39X CODE. ALSO, DON'T BLAME WINDOWS FOR FIREFOX APPLICATION ERRORS. AND...NEVER SUGGEST A WINDOWS REINSTALL FOR FIREFOX ERRORS!!!

On all our computers it seems impossible to sign into Outlook...several laptops and 3 desktop...even a new Apple device. Enter your email address and then taken to the next page (see attachment). sign in works with Edge! This has been happening for maybe a month. Very frustrating! NEVER opens the next security window, the 'spots' just keep moving forever...selecting "Back" just repeats the cycle.

Since the recent Firefox upgrades, I am no longer able to log into the social security site using ID me. Previously, I logged in with no problem but now get a 400 error message saying the website is too large. Of course I have emptied cache and cookies and reloaded Firefox but nothing works. Apparently the error lies within the Firefox upgrade since before upgrading, there never was a problem logging in.

Spinning circle when attempting to view a news articles. Tried other browsers and they all work Ok. My issue it seems with the FireFox browser. Thank you for any help.

Can the notification for upgrading be controlled on ver 143 on linux. It keeps appearing and as a user I should be able to silience or have it notify me at a period I prefer instead of interrupting browsing.

Using version 143 PIP does not work on different workspaces. If I open PIP the PIP only remains on the desktop that FF is on and the PIP disappears on othe workspaces.

The issue started about one week ago (today is 10/11/25). When I wanted to print while in Firefox browser, the print never executed. Instead the screen froze as did the browser. I had to do some experimenting to use my pointer and open a different browser. Yes - besides the pointer being frozen (all that showed was an hourglass) my keyboard was also frozen. When I finally opened a different browser and printed the same item, no problem. I had to close Firefox to be able to fully use my laptop again. I searched the solutions and none had an effect. Firefox would still freeze/hang/lock up when trying to print. The browser is up to date.

In one of my Firefox installs, the Profiler automatically starts recording every time I open Firefox. There's a button on the right that looks like a speedometer and it is blue until I tell it to stop. Then it is taskbar button color.

Profiler instructions at https://profiler.firefox.com/docs/#/./guide-removing-profiler say to simply drag this button off the toolbar and it will stop record. On restart, it's back on the toolbar, and it's recording.

I have tried refreshing Firefox. Doesn't help.

I have tried uninstalling and reinstalling Firefox, and then setting up a new profile. Doesn't help.

I have tried deleting prefs.js. Doesn't help.

I have tried opening up the developer console, opening settings, and unchecking "performance." Doesn't help.

I searched the registry and found a key called MOZ_ENABLE_PROFILER (iirc, something like that). I set it to zero. Doesn't help. I then deleted the key entirely. Doesn't help.

How do I get rid of this thing? It must be a registry setting of some kind, as it appears in whatever Windows account I open Firefox from, but I can't find it. It is deeply frustrating as the computer it is happening on is my oldest computer, and I don't want a recorder running in addition to Firefox.

Hi All,

I was using the following CSS to hide the navigation images and show only text labels on the context menu for the Back, Forward, Reload and Bookmark Page menu options...

/* Content Area Context Menu - Navigation Vertical Text */
#context-navigation,
#context-navigation > menuitem{
  flex-direction: column !important;
}

/* hide images */
#context-back image, #context-forward image,
#context-reload image, #context-stop image,
#context-bookmarkpage image{
   display: none !important;
}

/* show text labels */
#context-back:after, #context-forward:after,
#context-reload:after, #context-stop:after,
#context-bookmarkpage:after{
   content: attr(aria-label) !important;
   margin-inline-start: -19px !important; /* this pushes navigation text items to left, aligned with other menu items below */
}

It worked up until a couple of versions ago, but something has changed, and my CSS is now broken, and those navigation icons are back.

My context menu now looks like the attached image below.

Any help with showing only text labels on this menu is appreciated.

Thanks.

Bonjour en voulant aller sur un site connu et auxquels je vais j'ai eut ce message je n'ai rien modifié sur mon ordi d’où cela viens t-il et surtout comment y remédier. Merci "Pourquoi ce blocage ? Quelque chose dans le comportement du navigateur nous a intrigué.

Diverses possibilités:

   vous surfez et cliquez à une vitesse surhumaine
   quelque chose bloque le fonctionnement de javascript sur votre ordinateur

Des difficultés pour accéder au site ?"

On my linux system, I have two users. If I log in as user A and use FF and leave a bunch of tabs open, I can view those tabs again later if I restart my computer and log in as user A, so FF remembers its history.

No Problem Scenario Logged in as A - open FF - open a bunch of tabs - CLOSE FF log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are there

Problem Scenario Logged in as A - open FF - open a bunch of tabs - leave FF open (don't close FF before...) log out of A log in as B - do stuff log out of B log in as A - open FF; all the tabs are GONE

If I run into the Problem Scenario, I can sometimes use these steps to get the history/tabs back. https://support.mozilla.org/en-US/kb/how-restore-browsing-session-backup

Whether the steps work or not, the Problem Scenario is annoying. I don't know what causes this. My desktop manager is KDE.

Hi,

the password manager (about:logins) is a very handy feature, i use all the time. However, tehre is so many pages where the FF password manager fails to suggest the correct login user name to fill in the "user" field. (Interestingly, the password fill is much more accurate).

To start with: for logging in on THIS VERY SITE for posting this question, I needed to:

1. manually open the FF logins page
2. enter the url "accounts.firefox.com" for search
3. pick the entry
4. copy the username
5. swithc back window
6. paste and confirm.
7. repeat for password (I think - or came this at least suggest correctly maybe)

What's going wrong? Is my installation broken - or is this for all users the same experience?

Tks

Hello, I recently purchased and started using the Hyperx Cloud 3 wired headphones. When I watch a YouTube video or shorts with these headphones, if I skip forward a few times or scroll to watch a new short, a loud popping noise occurs in the headphones. I turn the volume up and down, and it fixes it. Interestingly, this doesn't happen in other browsers, only in Firefox. This is very interesting, and I can't figure out why. I wanted to share this with you because I love Firefox.

NOTE: There's no problem with the headphones; they work perfectly. This is an issue only in Firefox.

On our web site (www.outlookmovie.com) we have the option to print documents and we also have a watermarking option

when we do a print and save pdf from firefox > file > print and save a pdf if the option watermarking is off , it works, if the option watermarking is on, it does not work (the pdf exported is zero octet)

could you help us resolving this issue ?

By the way it works when we use Chrome or Safari

Thx you very much for your help Marc Jenny mjenny@mjenny.fr

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.
