So I have a following problem

FF 124.0.1 Windows 10 N edition Installed media feature pack

When trying to play twitch video it shows error 4000 and when trying to play stream from youtube it shows that your browser can't play this video.

Problem is that FF was able to do it like 6 moths-year ago (not really watching stream videos)

was trying to reinstal media feature pack, firefox, chcecknig nighgtly build but without sucess and have no clue what can do more

Firefox takes a very long time to open the first tab. After it opens, subsequent tabs open relatively quickly. I've tried self help suggestions like clearing cookies, cache and history, updating, even removing home page content. Nothing helps. It's getting intolerable and I end up switching to other browsers rather than sit and wait. Starting to even dread using firefox. Running Sonama 14.3.1 on my iMac. What else can I do?

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

I say crashing - it will not open. The closest I get is that it will say 'running troubleshooter mode', and then immediately close again before I can even see the actual browser. This issue does not occur with Chrome or DuckDuckGo, so it is not an issue with a Microsoft Family account. This issue is not related to missing or corrupted redist files, as I have installed all of the latest files there. I would like to switch to Firefox, as I use it on my phone.

Thank you for any help.

Hi,

I like to use separate user accounts / X sessions for work and personal stuff. Whenever I switch from one session to another (ctrl+alt+Fx), it usually takes a few minutes for Firefox to get responsive again. Sometimes it never does (typically on Mondays, after working in my "personal" session all week end, and switching back to my "work" session). Other applications (xterm, qpdfviewer, etc...) don't seem to be affected at all. Is there something I can do to fix that ?

Thanks,

 -Olivier.

Above 70-75k characters, text input fields on any site have a ton of input lag -- like, I have to wait 10s after I type a sentence for the sentence to finish slowly updating letter by letter. I've tested across multiple sites, and in Private mode (to confirm it's not caused by extensions, none of which are allowed in Private mode).

I also tried setting `accessibility.force_disabled=1` as suggested here and here, but that didn't help (and yes, I restarted). Disabling hardware acceleration didn't help either.

I don't have the words to describe what's happening here. Please see screenshot. Frequently when using Firefox- since the latest update, it's up-to-date on up-to-date Macbook Sonoma 14.4- this starts happening, when I move around my cursor, the images get all funky, it seems to be pulling in visual information from multiple tabs. Restarting the app clears it out, until the next time it happens. Any thoughts on this?

I have noticed a bug with how the Firefox icon appears when launched in the Windows 11 taskbar when the never group option is enabled. When Firefox is launched and is the only application open in the taskbar, there is no label present next to the icon like other programs have when launched. There is the little line underneath the icon though indicating it is launched but that is it. As soon as I open another application though, the label will also appear for Firefox. This is only a minor annoyance but is definitely as bug at least for me and should be pretty easy to fix. I will attach screenshots of the behavior. In the first screenshot, you can see that Firefox is open but has no Text label like it is supposed to. The second screenshot is as soon as I open a second application.

I am on Windows 11 Home 23H2 Build 22631.2792 Windows Feature Experience Pack 1000.22681.1000.0 Firefox Version: 120.0.1

When I try to open Firefox I am getting this error message: Error: platform version '124.0.1' is not compatible with minVersion >= 124.0 maxVersion <= 124.0. Does anyone know how I can fix this? Deb PS I need simple instructions, I'm not terrible techy.

Hello,

For an unknown reason, my firefox sometimes is really slow to startup.

It can take up to 10 minutes before the webpage start to load. My hardware is not that bad. I try to use the "performance" to capture the issue : https://share.firefox.dev/3x2rgHj I don't know if there is something to see because, the tool is also slow.

It happens on 3 different computers on linux.

I try to disable all extensions and without telemetry but nothing change. I'm reporting the problem now but it's much older

If you have a idea to fix this issue please share because it's really annoying.

Hello,

Clicking to open Firefox gives me the following error message:

Error. Platform version '120.0.1' is not compatible with miniVersion >= 120.0 maxVersion <= 120.0

Can't open firefox! I'm running Windows 11 version 10.0.22631 Build 22631

Thanks! Julie

Hello, since today I am experiencing instant crash on start up. It was perfectly fine yesterday (10 hours ago). Even attempting to open safe mode when offered also instant crash. Firefox is currently unuseable.

I believe the recent 124.0.1 is the issue ? Can this be confirmed, where can I check if this issue is widespread & the ETA to an eventual fix ?

Within the last few days, I've noticed I'm losing functionality in certain online apps through the Firefox browser.

When I'm on Instagram, I can't check direct messages: the function stalls out without resolving.

In Gmail, I'm unable to embed an image in an email. I can attach it like normal, but the embed button doesn't respond.

In Starry AI, I'm unable to use any menu options at all, I'm stuck at being logged into the account and can't logout, check my settings, or request help. I receive this message: "Application error: a client-side exception has occurred (see the browser console for more information)"

When I follow up on this, I get this pop-up message: Resource of last-private-context-exit is missing a browsingContextID or innerWindowId attribute resource-command.js:917:13

What can I do to fix this issue?

When in Google Sheets in Firefox a single scroll click of the mousewheel takes me to the very bottom right of the sheet. The scroll wheel is then disabled vertically and horizontally.

Error is verified for all Google Sheets. Problem does not exist when accessing these sheets in Incognito Mode.

Error does not occur when accessing these sheets in Chrome.

Sheets is all but unusable without mouse scrolling capability.

I get this error in my console XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so: libwayland-client.so.0: failed to map segment from shared object Couldn't load XPCOM.

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

When I open Firefox. Firefox Will NOT open any websites. If I disable ublock origin then enable again Firefox works but I get all the ADS. What I have to do is: Close firefox and restart Firefox but then I get this message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." Sometimes I have to restart Firefox as many as 10 times before Firefox works. I got to the point where I stop after the second try and just switch to Brave browser.

Before: Firefox use 99%. Brave Use 1% Now: Firefox use 75%. Brave use 25%

On a fresh install of openSUSE Tumbleweed 20240313 with KDE Plasma 6 (Wayland), the X button in the upper right corner of the screen does not allow you to click it when the pointer is in the upper right corner of the screen. Default behavior in KDE is to just let you close the window anyways even though the button itself is circular.

Is there any way to change this?

Firefox version: 119.0 (64-bit) OS: Windows 10 Home 64-bit

Hello,

Whenever I open a local HTML file, Firefox tab will crash. This happens if the HTML file size is big (>4MB), smaller file doesn't crash.

I've tried opening the file on Chrome, it doesn't crash and open just fine. So it seems like this is a bug with Firefox.

I've uploaded the HTML file if anyone wants to test: https://www.mediafire.com/file/ipmu7ugrd2vvelr/LICENSES.chromium.html.zip/file

Thanks
