Firefox Support Forum

I have found that Firefox does not play some audio files, for instance on Wikipedia and WaniKani, such as the audio on https://en.wikipedia.org/wiki/Erhu and https://www.wanikani.com/vocabulary/%E9%9F%B3. When inspecting network activity I can see that an attempt is made to load the audio on Wikipedia, but it does not play. On WaniKani however, no attempt is made. (WaniKani uses .webm for sound, maybe that has something to do with it?) The problem appeared after the update to Firefox 118 and persists in private browsing and troubleshooting mode, but does not occur in GNOME Web.

When I use a vpn with firefox (not the firefox vpn), I cannot open normally blocked websites such as twitter or youtube, and instead they open in a sort of half-loaded state (see image). I don't face this problem with other browsers. I have tried deleting and reinstalling firefox, but it doesn't seem to work. Can anyone help out?

Hello, I am struggling with a bug specific to Firefox (108.0.2) in which I have an XHR Post that is being blocked by dev tools only when a google captcha is selected. Here is the website that the bug is happening on. Per comment suggestions I've added a screen shot of the URL being blocked in dev tools.

My overall goal is to have this form post it's action and post the form data to another endpoint (https://beeceptor.com/console/preferencecenter). I am able to successfully post data to beeceptor with the captcha selected when testing in Chrome, but as stated not Firefox. If the form is submitted without the captcha selected the data is successfully posting to the beeceptor endpoint- this behavior is happening with both Chrome and Firefox which I am sure means something is wrong with my Javascript which can be resolved later.

Looking at the console in Firefox I am consistently seeing a XHR Post blocked to the beeceptor url with captcha selected. I have gone through several iterations of this code to resolve the issue, none of which have successfully worked. After many, many, hours of digging I have done the following to no avail.

• Cleared Cache
• Ran in Safemode then back to regular mode (one article this appeared to fix for a user)
• Ran in Private Browsing
• Adjusted CORS accordingly

There are more items I've attempted that I can't remember off the top of my head.

Any help with this would be greatly appreciated as I have hit a wall.

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. :)

Starting today I am finding it extremely hard to login to some websites. All Firefox does is just sit with a spinning circle after entering a user name and it locks up the browser to a point the I have to go to the Task Manager to stop the FireFox process. I have restarted my computer and refreshed FireFox. I have scanned my computer for malware using Norton 360, Malwarebytes, MSERT, and Windows Defender and all negative. I am having no trouble signing in to a site like https://my.account.sony.com using Edge but using FireFox now is impossible. This needs to be fixed.

Since Firefox update 19.0,1 flightradar website freezes when I click on an aircraft...

Using brave browser no problems.

windows 10 laptop with windows security all updated.

On both my old laptop and a new one (so a new installation of Firefox), I'm unable to load Frontier Airlines' website (www.flyfrontier.com) and get a time-out message:

The connection has timed out

The server at flyfrontier.com is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

This happens even with all of my extensions disabled, with enhanced tracking protection turned off for that site and with HTTPS-only mode and DNS over HTTPS disabled. It also happens when using Firefox in safe mode. Safari loads the same website very quickly and with no problems. Does anyone know what might be going wrong? Thanks.

I'm using firefox 119.0.1 Version on a Steam deck(SteamOS) and installed using the Discover app

when in browser i cannot click on the "Open the file browser" icon that appears on websites. Also i cannot open the Downloads folder within the Menu bar from firefox I tried entering into safe-mode and still couldn't open I also tried using another User Profile under "Right click Firefox -> firefox profile manager" to try to see if it was something from my user profile that was causing the issue but i also couldnt open in another profile.

I also tried on a different browser to see if it was my device problem but i could open it. i tried on Brave and Chrome and it worked.

i dont know what to do, this was working normally last week and now it doesnt work, Even in another profile with no configuration done no extension and not logged in the "Open file" button doesnt work

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.

Hi, I updated Firefox to v119.0.1 and on Amazon Music site, the "navigation menu" is missing, see attached file. The "menu" is present on Edge (see bottom frame of Edge screen shot). What should I do to back the frame?

Best regards, Andrei

EDIT: Of course, moments after I posted this I discovered the solution - uBlock Origin was preventing the images from displaying properly. Please feel free to close/delete this question.

Hi Firefox community,

I'm looking for some help troubleshooting display problems with one specific website. (I've had no other issues like this with any other webpage.) This website is a log that we use at work to track cases.

The first screenshot is what the webpage is supposed to look like when displayed properly (loads properly in Internet Explorer). The second screenshot is what I see when I try to access the page on Firefox. I've also found that the links in the buttons don't work either.

A couple of things I've already tried based on forum suggestions that haven't fixed it: - Refreshed/reloaded the page - Deleted cookies/cache - Updated Firefox (currently version 119.0) - Reset Zoom, minimum font size, page style, checked that Javascript was enabled, unchecked hardware acceleration - Turned off Enhanced Tracking Protection, verified that Firefox wasn't blocking parts of the page through the padlock icon next to the address bar - Restarted my laptop after all of this (using Windows 11 on Dell XPS 15)

Any suggestions or advice is greatly appreciated. It's not the end of the world if I can't fix it but it's just a bizarre error and I'd prefer to not open Internet Explorer every time I have to use this website.

Thank you!

Starting in August 2023, paying my Verizon (landline) bill has been a headache. That month I was unable to even log into verizon.com with Firefox. Curiously, the Opera browser (Blink) fared even worse. Eventually I realized that I could log in and seemingly have full functionality when spoofing as Chrome. I don't know what they f**ked up, but it must have been bad.

Since my September bill, I have been able to log in, but the page style is messed-up nearly to the point of non-functionality. See the images below. The header and footer of the "Payment is Due" page render normally. The middle section with billing information renders normally for a moment, then something happens...I'm assuming it's a JavaScript event...and the styling is lost. Clicking the Make Payment link then causes what should be a DHTML "popup" to instead render at the bottom of the page. The page scrolls down a little, but it's easy to miss the first time around. Knowing this now, I can continue paying my bill, but for non-technical users it's likely a nonstarter. Previously the payment process worked flawlessly for over two years.

I am in touch with their "Executive Customer Service", which tells me Verizon's web developers cannot duplicate this issue...which I think is a lie. I can duplicate the problem in Firefox ESR 115.4.0 (Linux) and the latest/last versions for Windows 7, including Waterfox G6.0, most with a very stock configuration (i.e. no LibreWolf).

Would anybody with a Verizon account please tell me if the bill payment process works normally for you? I assume my service being a landline makes no difference. There are several pages before actually sending a payment, and only the first page is relevant to this post.

I did a little web development years ago, but the current Verizon site is a bloated mess. I think they even track mouse movements, causing uBlock Origin to SCREAM. If this issue doesn't resolve on the Verizon side I will eventually solve it myself. If any non-Verizon customers have troubleshooting suggestions, though, I am open to ideas. So far I installed the Luminous addon JavaScript event troubleshooter, but haven't had time to learn it.

Thanks.

Hi, I've had this issue since I installed firefox on my current computer. The hover menu shows up on Youtube and some other video websites, but not on Twitter for example.

I followed what a forum post here said about dom.w3c_touch_events.enabled and HID touch interface, neither did anything for me (I don't even have a HID touch interface device on my list, not even hidden).

Need some help :P

Need a little help with About:Profiles page

have xfce but a weird bug on my machine its not a show stopper but annoying if i open firefox and type about:profiles ir shows you profiles on Firefox you get a box to open the file which should open Thunar (file manager) to show files, but mine opens Sublime text ????

See https://i.imgur.com/EErkzo6.png here I am on Arch Linux with Xfce & DWM combo spoke to other XFCE & DWM users they have weird issues like nothing happens or a text editor opens on theirs ?

So just wondered if it was a FF issue

Not exactly sure when it started, but youtube shorts are broken in Firefox now.

You can scroll to the next video fine, but if you continue to scroll to the next after that (3rd consecutive video) you get redirected to the first video you started with.

I did try to restart FF in Safemode, but no change. In other browsers (Chrome, Edge) its still working.

For a while Google Drive's cloud interface hasn't been able to show "information" about files, i.e. pictures, text, file-data. The fault is not present in Android, Chrome and Edge so it is not Google Drive that is buggy. I'd rather not change to another web browser. Please present a fix. Janne G win 10 home, v 22H2, OS-v 19045.3570, Windows Feature Experience Pack 1000.19052.1000.0

With version 105.0.3 (32-Bit) I have only trouble. Sorry to say, but most pages are not working. So I will probably now change to Chrome. Because I need a browser working and not 80% of addresses not. I don't understand the newer philosophie. I was enthusiastic Firefox user. But this year each version has more problems for me, using Windows 10. Each page I open I get "Increased safety risk". And that could not the world of security of today. I think Banks, Insurance and Healthcare don't have insecure pages without acitve signatures. But Firefox says this every time to all pages.

Have a good time, Gilbert

I have been having an issue for a week or more and no updates from the browser seems to fix that. The error reads: Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. This is occuring with a request to RBC banking. The same appears to be true but witrh different language for a request with Desjardins Insurance portal.The second link printed in red is the result after I cleared all cookies from Desjardins site. I can access many other pages within the two sites. RBC I am logged in (In black). Desjardins I am not yet as a user when these errors come up
