Firefox Support Forum

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.

Recently firefox stopped playing audio, I have searched through the settings multiple times, tried safari and google chrome and they both still work so here I am for help.

Running 127.0.1 (64-bit) on EndeavourOS, KDE Plasma, using Wayland. I've had severe crash issues and when troubleshooting I noticed this

Error: Failed to open Wayland display, fallback to X11. WAYLAND_DISPLAY='wayland-0' DISPLAY=':1'

pops up every time I start Firefox via terminal. Why wouldn't Firefox be able to open a Wayland display? Trying to force it with MOZ_ENABLE_WAYLAND=1 firefox doesn't do anything. I get the same error message.

I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

So i'm a basic PC user and not a Pro to solve Problems related to Web browsers. İ wonder if this happens to any one out there using Latest version of Firefox. (127.0.2 64bit) PS:İ use a app called user agent switcher to fix freezing or lagging or buffering. İ have read some where on the internet that youtube is doing it on purpose?. This happens only with Firefox but not with Microsoft edge.

Hi, Archived thread on this from 2023 has no answers. Why is this browser so slow now and why is it glitching with resizing my windows? Beyond a total reinstall - how completely inconvenient - I would like an EASY FIX.

NOTE TO MOZILLA - WHY DON'T YOU HAVE A SOLUTION FOR THIS, NO REASON TO GO TO COMMUNITY 'IN CASE' SOMEONE HAS THE SAME PROBLEM!!!

GET MORE REAL SUPPORT PEOPLE INSTEAD OF MAKING YOUR CUSTOMERS DO THE WORK!!

TAKES FOREVER FOR AN ANSWER, IF I EVEN GET ONE AND IN THE MEAN TIME I AM STUCK WITH PROBLEMS!!!!!

I cannot do anything involving a search, tab crashes. I have used Firefox for many years, and yes, I have updated to the current version. If I cannot get this resolved, I will have to uninstall Firefox and use another browser. Please advise. Thank you.

For over a month now i have a problem with youtube. It loads videos very badly. I have good connection speed, but 0 network activity and 0 buffer health in Stats For Nerds on youtube and videos dont load. I can wait for 10-15 minutes (but sometimes they load almost instantly) before video load 40 sec buffer and after that buffer ends i can wait for another 10 minutes befor it load buffer again.

This problem persist only in my firefox on my computer. I tried deleting all the extensions, reinstalling firefox, "refresh firefox" future, changing useragent, reinstalling windows (it was the time anyways) but it doesnt solve the problem. I dont have this problem in other browsers (edge, librewolf, chrome) on my computer.

OS: win 11 x64 Firefox 127.0 x64

I was sitting playing on the computer, I go to firefox browser and go to zelenka.guru, I look, and I'm not in an account on this site for some reason. I decided to go to another site, but there is the same problem, as I realized - for some reason I got out of all accounts on all sites.

Hello all. Having updated Firefox a few days ago, we can no longer sign into Instagram. This happens only on Firefox, only since the last update, and Firefox is the same browser we have been using for years with Instagram. The problem is the cookie permission window for Instagram a) will not make a selection and b) will not disappear/close. We have attached a screenshot. There are no close tabs/buttons anywhere on this window, and we have looked the full length of the expanded window. As we have not changed any other setting, have not added any software, and this only happens on Firefox, we can only conclude that we have missed something which may have changed or been upgraded with your last update. This is quite urgent, as this is to manage the Instagram account of a wildlife conservation charity. So far we have tried reinstalling Firefox, clearing cookies, and deactivating/uninstalling all add-ons, however this has solved nothing. Could anyone suggest a solution please? Thank you for your time and assistance.

Hi,

ist the famous and great Mozilla FireFox Developer team aware of the issue and is working on it?

I am happey to describe in more detail if required. thx

For the past couple of days when I watch videos on YouTube on my iMac it's VERY slow to start. Sometimes it takes minutes, at which point I have to refresh, and best case it takes about 1 minute to start.

I have cleared the startup cache, cleared cookies and restarted Firefox.

Also, YouTube works normally on both Safari and Chrome.

Not a super 'tech' guy so any basic steps I can take are appreciated.

Thank you!

Firefox keeps automatically skipping ads on youtube, which would be fine but now when i try to play a video i get a split second of a buffering ad, which skips to the youtube "please disable adblock message" (never downloaded ad block for youtube) and then a blank player, I'm not sure if this is a firefox issue or a youtube issue.

I've been experiencing a problem in Firefox where, when I scroll, the incoming part of the page momentarily goes blank and then loads to normal. This issue becomes more pronounced on pages with a lot of elements. Also, this issue becomes more vivid in smaller screens compared to larger ones. It feels like the browser is taking time to paint the part of the page.

This issue only occurs in Firefox. I have tried this in Chrome and Safari.

Here's what I have already tried:

• Disabled hardware acceleration and WebGL.
• Disabled smooth scroll and auto-scroll.
• Opened Firefox in safe mode (troubleshoot mode).
• Confirmed that I have no extensions or add-ons installed.
• Reset Firefox.

Despite these attempts, the issue persists. This problem is affecting the usability of the website. How can I resolve this scrolling issue? Any help would be greatly appreciated.

So, this is going to be an incredibly weird question, but is anyone else having this issue? As of about two days ago, any time I try and load a video on youtube it will refuse to load for upwards of 30 seconds, however if I toggle the new stable volume option off/on it instantly loads. It will then play for about 2-3 minutes or more depending on video length (sometimes way more) before the buffer bar will stop entirely, take over two minutes to load the video again, then keep playing. More often than not doing this multiple times per singular video. Often times it won't even load anymore at all and I am forced to refresh the page and toggle the stable volume once again.

I've tried disabling every single extension I have, including ad blockers, restarting the entire browser, and using a different account, and it still happens no matter what. However it is not an issue that occurs on chrome or edge, so I'm at a complete loss of what is causing this. Looking up this issue comes up with next to no results, so is it possible this is a youtube issue or is something seriously wrong with my browser and I need to re-install it?

when my operating system is in dark mode, and i browse a website that supports darkmode. the dark mode setting is not changed in containing iframes.

so the following javascript does return different results: window.matchMedia('(prefers-color-scheme: dark)').matches false top.window.matchMedia('(prefers-color-scheme: dark)').matches true

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas

In Firefox, after a reboot, how can I re-open my previous sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previous sessions.

Usually I just open Firefox, and this opens one browser, and then all of my previous browser, and tabs reopen, but this time Firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tabs, but it didn't.

After following the usual Firefox help guides, it still wouldn't re-open my previous sessions. Now if I ask it to open my previous sessions, it just opens the recent help guides, and not anything before the crash.

So is there a backup file of my missing sessions that I can roll back to?
