Firefox Support Forum

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.

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

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.

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.

All downloads I make inside of Firefox are automatically failing, with "Failed" message. This only happens in Firefox, Microsoft Edge downloads are perfectly fine. I've tried starting in troubleshoot mode, disabling anti-virus, clearing cache and downloads, rebooting PC.

Some recent changes in PC include: changing TEMP and TMP system variables to another drive (I've changed them back to C drive, had no effect) and making C drive a dynamic disk. Yesterday downloads were working fine. Thanks in advance.

About 1 week ago Firefox with Windows 11 stopped displaying YouTube video comments. I've tried other browsers and I can see the comments.

I only have 6 extensions and have disabled all of them and still have the problem. With Firefox in safe mode the problem goes away and I can see the comments. I've cleared the Firefox cache and hardware acceleration is off. I have the standard themes and using the default system theme-auto.

Any suggestions on how to resolve this problem? Thank you.

We still use some Dell 13g servers equipped with idrac 8. When I'm trying to launch the virtual Console the window opens up but nothing shows. This used to work fine in previous versions of Firefox. I can't tell from which version it stopped but it's not long ago. Also idrac 9 console works fine in Firefox When trying to open console idrac 8 in Chrome it works fine Any idea what could be causing it? Any config switch to tweak?

Hi, I've upgraded to Windows 11 today and couldn't open Firefox since. Things I've already tried:

• Reinstall Firefox and delete all old files (Appdata & Program files)
• sfc /scannow and DISM.exe /Online /Cleanup-image /Restorehealth
• Windows compatibilty mode
• Firefox Troubleshoot mode won't open either
• ipconfig /release & /flushdns & /renew
• netsh int ip reset & netsh winsock reset

When opening Firefox in any way, i get a white window/just the window border which immediatly closes. When trying to start troubleshoot mode, the small window has the same issue.

I also checked the crashlogs and none were generated. The Windows event-logger also has no entries.

BTW: Here is a video of whats happening: https://youtu.be/AJP4rqZFxlY

I have no idea what to do - send help please.

On this webpage on the link below, when the 'Comments' button is clicked, nothing happens. It works via the Chrome browser.

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.

Google search no longer works on Firefox. Other browsers have no problems. Changing the default search engine on Firefox works (eg Bing), BUT. It can now find Google Maps, but Google Maps cannot find a location, because it uses a Google search. I tried the fix in about:config, but it had no effect.

my firefox youtube is broken, every time i close firefox, and open youtube, the comments and the sidabar wont load, until i clear my cookies and login. so that fixes it, but its not permanent. if i close or restart firefox, id have to repeat this process again. and yes, ive disabled all my extentions and cleared cache. and updated firefox.

I have a Lenovo ThinkPad X1 Yoga Gen 6 (20XY005MGE) with Win11 Pro.

All of a sudden, Firefox does not play any sound. I notice that it does not show up in the volume mixer. I tried:

• this solution: https://support.mozilla.org/de/questions/1278299
• Reboot the PC
• Uninstall and reinstall Firefox
• Deactivate all Extensions
• I worked my way through the manual pages (none of which mentions Firefox missing in the volume mixer)

Youtube does not play sounds, the Spotify page notices that it cannot play sound (the spotify App for Windows works fine, though). News sites (tagesschau.de / video, deutschlandfunk.de / audio) play the video, but no sound.

I had the problem a few months ago already but I cannot recall the solution :(

Thanks for helpful hints!

I am having an issue where youtube videos played at higher quality stutter when put to fullscreen. Up till about 720p60 works fine, at 1080p60 and above the framerate becomes unstable.

Things I have tried: - I have tried going into media.media-capabilities.enabled and changing it from false to true - I have set network.buffer.cache.size to 262144 - I have disabled all my plugins - I have tried changing my user agent to windows/chrome

My current setup: Firefox 122.0, Macbook pro Sonoma 14.1, Apple M1 Pro chip

Curiously, if I make a new firefox profile and play a video there, there is no stutter. Does anyone have ideas on how I can fix my current profile?

I saw this post https://bugzilla.mozilla.org/show_bug.cgi?id=542690 where it seems implied that it should work, but on LMDE 5 w. firefox 98.0.2 64-bit scrolling horizontally w. touchpad doesn't work for scrolling on pages nor for scrolling the tab list at the top.

Error message when accessing business websites which use Cloudflare: "ERROR 1005 ACCESS DENIED DUE TO ASN 9009". This seems to be because Firefox is using ip addresses which are blacklisted. This has been checked with blacklist services such as DroneBL. I am not using a VPN. I constantly clear cache & cookies from Firefox and then restart the computer. I am not ignorant or stupid. Why is Firefox using blacklisted ip addresses? Is it because of M247? Is there any way around this extremely annoying problem? Thank you for your response.

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
