Firefox Community Forum

I am using Firefox on Windows 11, in the process of switching from Chrome.

I run Cockpit (https://cockpit-project.org/) on web servers that I manage, and when I log into it on Firefox the screen flickers constantly, making it unusable.

There is no issue with any other web sites I have visited, and I can still use Cockpit when in Chrome. So ay suggestions on how to troubleshoot and resolve the issue with Cockpit and Firefox?

I’m currently facing a very frustrating issue with Firefox. I have been using Firefox for many years, and it is my favorite and most comfortable web browser for my day-to-day work. I rely on it heavily as all my bookmarks and other important details are saved there.

However, over the past few weeks, Firefox has been crashing more than 10 times a day. I have already tried all the troubleshooting steps available in the forums and through AI support, but none of them have resolved the issue. I also tried installing and using the Firefox Beta version, but the problem still persists.

In our environment, other users and devices are not experiencing this issue, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please help me troubleshoot this issue? I am attaching the error screen that appears after the crash along with the crash report for you

Due to an internet outage, I got forcibly signed out of my Firefox account. I signed back in, but all my login info and passwords are just gone. I still have my browser history, and I'm even still logged in to some of my accounts, so I know some of my cookies and cache are intact.

The recent update changed how the mute button works in Firefox, before it would replace the icon and would show text and whatnot if it was muted or wanted to autoplay; now it just always shows the mute/unmute button in a tab playing audio. This would normally be fine but it is causing my tabs to constantly be shrinking and expanding whenever the audio changes in a tab, and it's really frustrating me and it feels like an overall far worse user interface design than it was before, even if people were complaining about it. Is there some sort of middle ground where I can set a maximum tab size or something? I know this used to be a feature in about:config but it doesn't exist anymore for some reason. I've also tried using a userChrome CSS code for it that I found online; it got rid of the button but it still made the tab size change and the code I tried using for maximum tab size also didn't affect that. Really starting to frustrate me! Please give me any advice I feel like I've exhausted all my options lol

Bonjour,

depuis le début de la semaine lorsque j'ouvre firefox mes marques pages de ma barre personnelle sont disparu et ne sont pas non plus dans l'historique de récupération. il faut que je "répare firefox" pour qu'ils reviennent. mais le problème revient. parfois plusieurs fois par jour. Je n'ai jamais rencontré ce problème auparavant. J'ai un message de firefox qui m'indique que firefox est ouvert ailleurs. mais je ne sai pas où. merci de bien vouloir m'indiquer ce que je dois faire

WebRTC DataChannel worked perfectly in Firefox 147 and earlier, but after upgrading to Firefox 148, send() throws InvalidStateError immediately after onopen fires. Same code works in Chrome and previous Firefox versions.

const dataChannel = pc.createDataChannel('kvsDataChannel', {

   ordered: true,
   maxPacketLifeTime: 3000

});

dataChannel.onopen = () => {

   console.log('open, state:', dataChannel.readyState); // Shows "open"
   try {
       dataChannel.send('hello'); // Throws InvalidStateError
   } catch (e) {
       console.error('Failed:', e.name, e.message);
   }

};

Error: InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable

Environment: Firefox 148.0: Fails OS: Windows 11 Firefox 147 and earlier: Works

Question: What changed in Firefox 148 that broke DataChannel send()? Any workaround while this gets fixed?

господа,здравствуйте,помогите пожалуйста,любое видео разворачиваю на полный экран на мониторе HDR,а оно тусклое,никак не могу победить эту проблему,я бы отказался от всех остальные браузеров,но вот это единственное что меня останавливает

Sometimes, I cannot click on an option on a form (on my up-to-date Firefox, on Windows 11 - help, please! Its usually only when the options are shown as little buttons or squares to tick off. Its not my mouse because it works for the usual mouse works.

I can't enter the tick/click necessary on this form to say "Email me when someone answers this thread" Cheers, Carol

I am using Firefox on a W11 64 desktop. Until recently (the most recent upgrade, I think) all worked well. But since then although the relevant box is ticked in settings (aboutpreferences general), on opening Firefox the tabs from the preceding session are NOT restored. This is extremely inconvenient.

Have any others found this same problem? Any work arounds?

I have 18 shortcuts that I have added to the Firefox desktop, but every time I open a new link, a shortcut is added to the desktop. How do I keep these unwanted shortcuts from being added to my Firefox desktop?

I have left Shortcuts toggled on, since I want to see the 18 shortcuts that I have manually pinned. Fine so far.

I have unchecked Sponsored Shortcuts, but I still am seeing sponsored shortcuts. What am I doing wrong?

Firefox not responding. I have tried everything on the Help pages. I have tried reset of everything. I have uninstalled and reinstalled from scratch. Still: when I open it: Firefox does not respond. And everything else also is very slow then. In Windows joblist I can see Firefox with 7-15 threads. One of them "not responding". I have no problems with Chrome nor Edge - W11, 16GB Ram

Is there anyway in the setting to stop a shortcut from being added every time I visit a site? I only want sortcuts that I use. I have attached a screenshot circling the ones that keep popping up as an example.

Respectfully, Rhonda

Normally Ctrl+Shift+T reopens the last tab I closed in that specific window, but after the most recent update it reopens the last tab I closed in /any/ window. Is this happening to anyone else?

Long Delay occurs loading multiple websites, from facebook to other sites and I often get a delay of over 20 seconds with any site involving a CDN connection of various types. I am using W11, latest version of Firefox. 148.0 (Says latest version)

When it happens I can see the connection url in the bottom left hand corner includes a CDN part. Settings are Proxy settings "Use system proxy settings"

• DNS over HTTPS is set to "default protection"
• IPv6: ISP is has just changed from gigaclear fibre to toob fibre, but it has made no difference.
• Have cleared cache. No change

This is very frustrating. Started a couple of months ago. I have ended up using Chrome ratherthan Firefox and I am close to giving up with firefox. Help appreciated.

BT yesterday misspelt my email address with an additional 'h'. Although the original address has now been restored, firefox will no longer accept the original version (displaking a red sticker saying 'email address or user name misspelt') and I can only read my emails using on my Windows laptop using Microsoft Chrome. As I dislike having anything to do with google, please can someone explain how to resolve this problem (by removing cookies or whatever else).

Many thanks,

Oliver Crichton
