Firefox Community Forum

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

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

Over the past day or two, I've seen firefox incorrectly render fonts on a couple of websites. So far, I've only noticed two websites effected: quotientapp.com and xero.com (not the actual landing page, but rather the login page and other pages available after login https://login.xero.com/identity/user/login). This problem may extend deeper but these are the only places I've found them.

At first I thought my eyes were playing tricks on me but nope, something definitely not right. No new addons have been installed on my system. I've also deleted all local storage / cookies (via the Inspector) for these sites thinking it must be some caching issue - but no, it's still doing it.

Inspecting the font-family shows the issue (this is from the page https://go.quotientapp.com/sign-in) - have attached the images below of what I see.

I do use uBlock, but it is disengaged on Quotient and Xero (these are work related sites, they show no ads). Other add-ons I have installed include Bitwarden, Dark Reader, Firefox Multi-Account Containers and Reddit enhancement suite. I've ensured all add-ons are up to date as of this posting.

FWIW I do allow all the extensions above (with the exception of Firefox Containers which I don't allow) in private mode.

Any insights on how to get to the bottom of this?

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.

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.

Hi.

Ever since I upgraded to version 123.0.1, I am constantly getting slowness on websites stuck in "Performing a TLS handshake..." Eventually the websites load, but it's frustrating. I have read about the various solutions and have tried the following: Disabled IPV6 Refreshed Firefox Reloaded Firefox Disabled and removed all extensions Restart in safe mode Create new profile

This was not happening in version 122 and before. Microsoft Edge does not have this problem, but I prefer to use Firefox. I am running Windows 11 Pro. Any ideas?

Thanks

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%

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.

Using the arm64 version of Firefox on a Surface Pro X causes several graphical issues. These issues started either with a update of Firefox or drivers.

This topic has already been reported, please see here for more information and documentation: Reddit: https://www.reddit.com/r/firefox/comments/182iojx/firefox_arm64_graphical_problems_on_surface_pro_x/ Mozilla Connect: https://connect.mozilla.org/t5/discussions/firefox-arm64-graphical-problems-on-surface-pro-x/m-p/52086

What can be done to report this issue and help it getting fixed?

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?

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?

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.

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.

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.

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?

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.

CrashID: bp-5b2cb490-913f-4ffa-8f1b-35cba0240323

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 ?

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.

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.

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.
