Firefox Support Forum

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.

Firefox "Tabs" when operated automatically will not work on links within emails that I trust. When I manually select the link to open within a "Private Tab"(Personal, Banking, Shopping, etc)the link will work, and connect. I have checked the Windows 10(64) Firewall and my VPN, and nothing is set to block Firefox from connecting the auto-opening Tab. What is the trouble?

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.

I've been unable to complete the installation of the latest version of the Firefox browser for Windows 10 for several weeks because my Bitdefender online protection repeatedly blocks the connection to incoming.telemetry.mozilla.org saying: "firefox.exe attempted to establish a connection relying on an unmatching security certificate to incoming.telemetry.mozilla.org. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one."

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?

the size of the offered tabs became too huge in the address bar. Something happened in my browser and it reset all the settings. How can I reduce their size? They take up half of the browser screen

When playing any Ren'Py web build on Firefox Windows, the frames freeze while entering inputs. Depending on what is being displayed on screen, sometimes it will still continue despite the mouse movement, but most things just completely freeze up. Once the inputs stop, the frames will skip ahead to where they should be. This only seems to happen on Windows, as I was told it is not repeatable on Ubuntu using Firefox. This is also not an issue on Chromium based browsers.

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

Hi,

I'm switching from Edge and have a frustrating issue.

In Edge I am very used to having separate behaviour for links with left and middle click.

i.e. from Gmail, if I left click a link it opens in a new tab and switches to the tab, if I middle click a link it opens in a new tab but stays on the current tab

In Firefox both seem to be controlled by the single setting.

I have looked in about:config and tried changing a few flags but cannot seem to find a combination that works how I want it.

Can anyone help?

This is a real dealbreaker for me and I will switch back if there's no solution :(

TIA

Hello, I have a problem with the languages/dictionaries in Firefox (Linux) and would appreciate some help.

Currently the German language is not recognized in the spell checker or is apparently not available.

When I click on the context menu in a language field (right mouse button), only "Englisch (Vereinigte...." is displayed under "Sprachen" (which is "Languages" in the english menu).

However, the German language pack is apparently installed, because when I click on the link to add it in the context menu, the language extension for German already says "remove".

I would also be happy to provide pictures.

Incidentally, the interface in Firefox is already correctly in German.

Deleting cookies, restarting Firefox and restarting the system have unfortunately not helped.

Can anyone help me, I'm getting desperate?

Thank you very much!

I have several g-mail accounts that I used to open on Firefox - until yesterday. Now I'm getting a silly message below:

I'm working on ASUS, on Windows 86bit. If I reboot my PC g-mail works again for a couple of hours. I have no problem accessing my g-mail accounts from Chrome.

Any help? Thank you all Marina

I am trying to get rid of the fullscreen animation i have tried changing full-screen-api.transition-duration.enter and full-screen-api.transition-duration.leave to 0 0 but the animation still plays

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

I can no longer use my camera on firefox, firefox displayed some message about camera when we were trying to chat, but I missed it, I have granted relevant permissions on the site, that we use reularly. The camera icon on the address bar appears red, and I noticed that in Windows security, it lists firefox access requests, but shows no way to grant these requests.

I am not tech minded so please if anyone could keep it simple, I would appreciate it.

Often, when I go to history and try to restore session..it is greyed out. it occurs randomly, but It ALWAYS occurs after an update. This is so frustrating! It never happened on Edge or Chrome, not once. I know it might seem Karen-like fuming about it, but when you have dozens of important tabs open and they don't restore you too will become a karen. I'm almost about to uninstall Firefox because of it
