I have tried watching videos through chrome and other browsers by searching something via duck duck go and watching that video on duck duck go, and it works on other browser so it must be specific to firefox.

Whenever I try to watch a video, in the drop down bar firefox select to mute audio for some reason. I then select 'allow audio and video' and refresh the page but the video is still muted for some reason. This also happens when I try to use other video sites. This has only started to happen recently in the past two days (and yes I am updated to the latest version of firefox).

I used to be able to get on Amazon with no problems using Firefox. Lately, the website is all chopped up. Blue words with underlining appears on the pages. I can view Amazon just fine under Safari.

I can't login to the NY Times website using Firefox. I'm sure I'm using the correct password because I can log in using a different browser. I don't save passwords in Firefox. I enter them manually or use a password manager. As I said, I'm certain I'm using a valid password. I've cleared the cookies and all of the items under History on the Settings page. When I close Firefox, nothing is saved. When I contact NYT customer service, I was informed that they've had a lot of requests for assistance from Firefox users, and nothing was out of order with those users' NYT login; the problem was with Firefox.

Please advise.

I noticed this first when I had to force Google to go into dark mode even though firefox was already in dark mode.

I have searched through some issue reports and have seen a lot of people mentioning that their system theme is not being detected properly. This is not that issue. I can set the firefox "Website appearance" to dark or automatic at which point the UI of firefox itself does do into dark mode so no issues there. However if I go to a website that tries to query 'prefers-color-scheme' and set its theme accordingly it always returns 'light'. This is the case even if I set the 'layout.css.prefers-color-scheme.content-override' to 0 in about:config.

I used this website to test: https://septatrix.github.io/prefers-color-scheme-test/

The issue persists when opening a website in a private window.

Let me know if I need to provide additional information.

Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!

When I open the google maps website it functions normally for about 3-4 seconds, then firefox completely freezes not just that tab. Firefox is up to date and it happens with all addons disabled. maps seems to work fine when I access from other country domains (co.uk or .de) Also I have no problem with the site on other browsers. It does not generate a crash report.

This page just gives me a blank page.........and various other 'meta' pages/sites Facebook is fine Tried in Safe Mode but just the same.

I am unable to login to my Prescription provider's website (which I do every day). Problem started Sunday and still persists.

I am able to login using Chrome, so I know the website is working properly.

Help - I DO NOT want to use Chrome.

There is one domain that I get a "server not found" error for even after doing many things to fix it including everything here, https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can#firefox:win10:fx119, checking blocked URLs in the registry, running malware checks, safe mode, reinstalling FF after removing all FF folders from my system.

Before I did a completely clean reinstall, disabling the Open H264 codec (see attached screenshot) would allow me to access the site. But thinking it was needed, I did the clean reinstall. Now disabling it does not allow access to the site.

So far, I have not found any other websites with this problem. It's a .edu domain which happens to be the one I work for! What else can I do?

WhatsApp Web endless loading and general website whatsapp.com does not open correctly in FireFox 119.0. I tested other browsers: Chrome, Brave, Opera - everyone opens WhatsApp normally. I also tested FireFox on other devices with a clean installation - the problem persists.

FireFox 119.0, Windows 10, Windows 11.

When playing any youtube video in full screen, all I get is a black screen. Issue does not appear in private mode, firefox developer build or chrome. Other sites ex. go pro media plays videos in full screen without any problems

This was one of our primary suppliers for technology. Contacted them they just said "suck it up, princess".

Recently AWS started doing "human verification" on all VPN traffic to websites they host on their CDN(s). This results in all our Windows 10 PCs running Firefox ESR 102.13.0 going into an endless "Human verification" loop, never able to access the website.

On the Windows 2012 R2 server we have access to the above website works. We see "human verification" for a second or two and then the website is displayed.

So, copied my profile from a Windows 10 PC that doesn't work to the server and it works.

I've tried with tracking protection off. Turned off all adblockers, run in safe mode with all addons disabled, cleared my cache, deleted all cookies Created a new profile and still no go. Turned off Windows firewall, moved hosts file out of the way. Still no go. Also deleted prefs.js to run firefox as completely vanilla without any changed preferences.

I'm not inclined to install malware, so chrome based browsers are not an option. They are actually blocked so I couldn't install them even if I wanted to.

All PCs are on 21H2 3208. Upgrading is not an option at this time. PCs will be upgraded mid-late 2024.

All PCs are required to be connected to VPN at all times as we work from home. Being on call late into the night also means we can't just disconnect. We use NordVPN. Yes I know there is a lot of paranoia about VPNs being the source of all online crime. I just think that's an over-generalization. A convenient excuse.

https://www.scorptec.com.au did a similar thing earlier this year, but at least with them we get a captcha and can get to their site.

Could this be a browser issue, or is this more likely to be a Windows 10 issue? Also updated Windows 10 to latest patch each month and it's been the same for three months.

After upgrading to Firefox version 103.0 on Windows 10 I am no longer able to Login to https://auth.synchronybank.com/account/login . After entering my User ID and Password I stay on the Login screen with the gear spinning for several minutes then receive the error screen shown in the attached image. Clicking on Try Again" on the error screen produces the same error. Please correct ASAP.

Note that the Login from https://auth.synchronybank.com/account/login completes successfully using the Google Chrome or Microsoft Edge browsers.

Firefox is displaying a smaller font on some websites. It only does it new windows, not in a private window and other browsers are fine.

Screenshots attached show the correct size (first attachment) and the incorrect smaller size (second attachment).

It's not windows accessibility aka ease of access, as nothing else is affected. All pages are on 100% zoom. I've gone to settings -> font -> advanced and the "Allow pages to choose their own fonts, instead of your selections above" is ticked.

Any ideas please?

Hello, I am finding that Firefox display incorrectly and out of sync the subtitles in streaming services like Hulu or Amazon Video. Subtitles dialogs appear around ten seconds before the actual audio plays that dialog. It doesn't occur when I am using Chrome.

Thanks.

I am having an issue with a work site where the content is not being displayed correctly. This site uses microsoft single sign-on with my corporate account and it seems that this is where it breaks, as I am finding errors that point in that direction: GET https://autologon.microsoftazuread-sso.com/softtek.com/winauth/sso?client-request-id=xxxx POST https://login.microsoftonline.com/common/instrumentation/dssostatus Result: NS_BINDING_ABORTED

When I open the same site using Edge (sorry:) it works correctly. The issue is that I do not have control over that website and I use it to enter some work information and I haven't found a way to work around it. I have disabled DNS over HTTPS, HTTPS only mode, Deceptive content protection, allowed single sign-on for microsoft, deleted cookies, etc and nothing seems to work. I hope this gets looked into as it is really an issue that might affect everyone not only at my workplace but others that may use similar functionality. Thank you.

Hello, everyone.

4-5 days ago, I've noticed weird YouTube playlist behavior. When I start playlist and switch to a different tab (or minimize browser) first video will play normally and it will autoplay the next one. But after finishing playing 2d video (3d in some cases) video will just stop at the end of playbar and not autoplay the next one in playlist. Playlist for example: https://www.youtube.com/watch?v=giUY_pEKTzY&list=OLAK5uy_nKmglmCCbx14WeFyH8e7YGYcL5skYwnp0&index=1

It's rather easy to replicate, I can record desktop video if needed.

Expected behavior: I can start YouTube playlist playing and switch to a different tab or minimize browser and playlist will only stop after playing last video in said playlist (unless "Loop playlist" option is enabled).

What I've tried to do so far: 1) Googling: I only was able to find old thread and the culprit was extension: https://support.mozilla.org/en-US/questions/952608 2) Disabling Extensions and confirming issue in Troubleshoot Mode: Did not help 3) Clear cache & cookies for YouTube: Did not help 4) "Allow Audio and Video" autoplay for YouTube: Did not help 5) Confirming issue in another browser: Works as intended in Opera 6) Checking about:config: I'm not that savvy with Firefox config to understand what may cause an issue. Tried to change media.block-autoplay-until-in-foreground to False. Did not help, rolled it back to True.

What I have noticed: 1) Firefox recent update: 118.0.2 October 10, 2023: Correlates when I started experiencing this issue. 2) YouTube playlists plays next video continuously just fine if I don't minimize browser or switch to a different tab. 3) There is a Firefox extension that does exactly what I don't want in my experience: https://addons.mozilla.org/en-US/firefox/addon/no-playlist-autoplay-for-yt/ I installed it just to check. And yes, it does what expected and it is similar to what I'm experiencing. Although it stops playlist after finishing first video, my issues go into the affect after playing first video. (Deleted it after testing)

Before posting I've tried a few different things and here where things gets extremely weird: 1) It works just fine in Firefox if I log out from my YouTube account: (Incognito/Main tab) Do not work if I'm logged in, even in Incognito. However... 2) It works just fine in Opera if I'm logged in my YouTube account. 3) It works just fine if I open playlist in mini-player. (Current workaround)

After all that weirdness I attempted to Clear cache & cookies for YouTube and it did not help once again.

P.S. Yes, I use YouTube as a music player. :)

Hello,

For several weeks now I've been experiencing issues with accessing google sites. YouTube videos will constantly display the "Connect to the internet. You're offline. Check your connection." error page. Additionally gmail and google drive will constantly give the "OOPs" error message. Sometime the page will load w constant refreshes but this is not ideal.

I've done the following:

Clear history/cookies Opening in troubleshoot mode Disable hardware acceleration Refresh/Reinstall

Have even tried the following articles: https://support.mozilla.org/en-US/questions/1377868 https://support.mozilla.org/en-US/questions/1376015

Still getting the same results. Not having any issues with edge/chrome. Does anyone have anything else that could be done?

Firefox Browser 102.0.1 (64 bit) Windows 10 OS

Twitter's login page won't load when I try to open it in Firefox. https://twitter.com/ https://twitter.com/ loads just fine, account pages like https://twitter.com/firefox load just fine, and individual tweets individual tweets load just fine. But when I click the login button on any working page, or go directly to the login page at https://twitter.com/i/flow/login, all I get is a white rectangle in the middle of the screen that flashes a loading-spinner for a few frames every two seconds but never actually loads any page content.

I can log in just fine in Chrome, so the problem is specific to Firefox. The problem started at least a week ago, but I don't log in on my desktop regularly enough to know exactly when the problem started.

I turned my Browser Privacy setting to "Standard" and cleared all site data from Twitter, with no effect. I use uBlock Origin, but the problem persists when I disable it. The problem also occurs in Private windows.

Dear firefox support team,

Since yesterday I've been having twitter act oddly on my on my main twitter account, but only using firefox. It keeps being on the 'try again' option window as if the wifi isn't working properly, whilst the Wifi is okay.

It keeps giving me the 'https://twitter.com/?failedScript=main' address too. And I can't think about what Script might be running into an issue. I have access normally on my android phone and google chrome. Doing a 'safe' restart didn't help either, and disabling my extension carried no result either.

I figure, since I can log in on other platforms this might not be a twitter issue, but well, I'm asking here to be sure.

I put an image of the screen I get in the attachments

Thank you
