Firefox Community Forum

I have set four custom URLs to open each time I use my main Firefox profile - this works well. (I have several different profiles I use for different roles and sets of logins).

I frequently open new windows to hold a set of associated tasks.

If I specifically open a link into a new window, the new window only has that one tab - all good.

However, if I just open a new window (Ctrl-N), Firefox always opens four new duplicate tabs for my custom URLs.

Is there a way to limit custom URLs to the first window opened in a profile or to open custom URLs only if they are not already open in at least one window?

When I go to my church website, www.universalist.org, it automatically redirects to www.webhostking.net. How do I stop this? Both Chrome and Microsoft Edge block this redirect.

I am going through the https://support.mozilla.org/en-US/kb/containers#w_manage-your-containers page and I dont have the option to add new containers when I click on the icon. I am only shown the choice to open the current page into one of the default containers. If I open a new empty tab, this icon doesnt show up in the url bar.

I have gone through the manage extensions options as well and I cant find a similar option. Can anybody point out what I am missing?

I am currently facing an issue where videos on websites other than YouTube are not playing. This problem is occurring on browsers like Firefox, Brave, and Opera, but interestingly, videos are working fine on Chrome. I have tried various solutions over the past 2 years, including removing extensions, using private mode, installing web media extensions and codec packs, but nothing has resolved the problem. I am using Windows 10. I would appreciate any insights into why Chrome is able to play videos while other browsers are not, and I'm specifically looking for solutions beyond the usual suggestions like removing extensions or using private mode.

System: MacOS 13.5 Hardware: Apple M1 Max Firefox version: 116.0.1 about:support / Media Audio Backend: audiounit-rust Codec Support Information: Codec Name Software Decoding Hardware Decoding H264 Supported Unsupported AAC Supported Unsupported Opus Supported Unsupported Vorbis Supported Unsupported Wave Supported Unsupported

Having a problem with an mp3 content on all sites. In console I can see error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) Details: Error no decoder found for audio/mpeg

The same error shows when starting firefox from terminal: [Child 1234, MediaDecoderStateMachine #1] WARNING: Decoder=11dddc400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - Error no decoder found for audio/mpeg: file /builds/worker/checkouts/gecko/dom/media/MediaDecoderStateMachineBase.cpp:166

It seems like not a system problem, because I can open and listen an mp3 files in quicktime. And chrome browser also not having any problems playing an mp3 content.

Firefox installed with dmg downloaded from site, but also tried install with brew - same result. The problem occurs in incognito mode too.

media like .gif files and .mp4 files are used very frequently in the Discord servers I'm in and for some reason whenever those specific file types are used won't load/function. I noticed that while the DRM icon was present in the discord tab, that those two file types worked just fine; but I have no clue how to set it to always turn on for specific sites.

I was using my computer and Firefox all day to watch videos, browse twitter and Tumblr and whatnot until around 15:30 my time, when suddenly Twitter stopped loading my timeline. I thought it was an issue with Twitter or my computer. I restarted my PC twice so far and rebooted my modem (completely unplugged, left it alone for a min and plugged it in again).

I still cant load my twitter timeline, not even in private with all extensions turned off. It does load Tumblr, but like 80% of the pictures/gifs, even profile pictures do not load. When I search for something on Duck Duck Go it sometimes works but most times it just stays blank. Youtube videos either do not load at all, or stop loading/load endlessly at some point. I am still able to navigate the Youtube website tho.

I really do not want to use Chrome, but the latest update is just unusable. Am I the only one?

(I forgot the word for modem, dont judge me.)

Why does the Mozilla Firefox snap for Ubuntu keep changing the value of browser.opaqueResponseBlocking away from the default and selected FALSE setting to TRUE? This makes Firefox nearly unusable since the streaming video keeps being cut off when Mozilla Firefox snap for Ubuntu keeps changing the value of browser.opaqueResponseBlocking randomly during use. Specifically this is the 116.0.2 (64-bit) Mozilla Firefox snap for Ubuntu canonical-002 - 1.0 that is installed with Ubuntu 23.04. Please advise.

hello! i'm looking for a way to adjust the settings, if there are any, to copy and paste PNG images with firefox and keep their transparency intact -- rather than the solid black it has now. as i understand it there's been similar issues as of 8 months ago, but i'm unsure if anything else has changed in that time.

i'm not a full-on graphic designer or anything but i do use this fairly often as an artist to look at references and such, and as someone who's recently switched to firefox from chrome (which does support this feature) i'd like to know if it's as easy as clicking something in a menu or if that's not an option altogether. thank you in advance to anyone willing to help!

Hi! I just moved over to Firefox from a different browser, and there this minor thing that I noticed. Whenever I put a video on full screen, it looks like it alters the aspect ratio of my screen? Like there are black bars at the left and right of my screen instead of it filled all the way. Its very minor but it bugs me every time. Is there a way to fix this or not? Thank you!

I am using a Macbook Air M2 btw.

On some webpage, I experience delay response when I trying to search sometime. For example, in Google homepage after typing something or even gibberish the page froze and not responding for about 10 second but the browser is still functioning (meaning I can still move other tabs or open option). Once that 10s delay is over, it responded with my result. And something when I when to search back something again(not in the homepage), more of the time is response back fast like 0.2s but other time the same 10s delay. This problem also happens in some other website but not all in their search bar. I have try in safe mode. disable all my extension, reinstall Mozilla Firefox, check any windows update and such. Also other browser does not have this problem such as chrome and brave. If this problem still persisting then I would such to other browser but prefer not to as I quite fond of Firefox. Thanks for your help in advance.

Error code: SEC_ERROR_REVOKED_CERTIFICATE For Xfiniti.com email (Comcast). I saw many other questions to Mozilla on the same issue, so it's not those certificates. Edge connects just fine, as does Safari on my phone. Mozilla is the one with the problem, and you need to correct quickly, please. I need my email for many daily tasks, and it will be a lot easier to move to another browser than to another email.

I am unable to sign into Costco.com using Firefox. I get an error message:

    "Bad Request - Header Field Too Long
    HTTP Error 400. A request header field is too long."

Turning off all extensions didn't help. Opening a private browsing window DID work. Using Chrome DID work.

Thanks!

My Firefox is having some problems relating to audio.

If I open a YouTube video, the image will play but there's no sound, on Twitter also, and so on. On YouTube Music the player won't even start, giving the error "An error occurred. Please try again later." I noticed that the stereo icon that shows up in the tab, which allow you to mute the tab, won't show up when I'm playing a video on YouTube, Twitter, Vimeo, and so on.

Only Firefox has no sound, it's not muted in the Volume Mixer, neither in the app volume settings in Windows. I've followed everything suggested here here and here.

I think the problems may have started after I reinstalled my graphic card driver, but I'm not sure since I don't use this computer very often. I have a Windows 10 and my graphic card is a Nvidia GT 630, and the driver version is 474.44.

After a recent change of my website's name registrar, Firefox (both on Linux and Android) has been running into issues finding the server/address. I suspect this has something to do with DNS, whether it be DNS over HTTPS (DoH) or otherwise.

Specifically, this seems to happen when DoH is on (as shown by about:preferences#privacy). I have confirmed that `curl --doh-url <cloudflare DNS query> <my website>` also fails to resolve the request.

This leaves me with a few outstanding questions:

• Do I have any control of whether the DoH request fails? Is this something I can fix through my host or name registrar?
• The TRR mode shown in about:preferences#privacy appears to be different than the one shown in about:config (2 versus 0, respectively).
• Shouldn't Firefox be falling back to normal DNS? I have confirmed via `curl` that my website works fine over https.

Firefox and curl results for Linux confirmed on two machines on the same network.

Firefox beta release: 116.0b6 (64-bit)

On sites such as BBC.com, Youtube.com and Facebook.com I am not getting the normal cookie consent pop-up option which used to automatically show on opening the sites. Other sites are still showing the cookie consent option pop-ups. This means I cannot select if I wish to accept or reject cookies on several sites that used to allow me the option.

In checking about:config, the cookiebanners.service.mode is set to 1, which I believe this the correct setting for enabling the cookies consent pop-up option.

Is there any fix for the cookie consent pop-up not working on certain sites within the EU? I am not using a VPN or pop-up blocker. Tracking protection is set to Standard, cookies and site data are always deleted on closing Firefox and "Do Not Track” signal is set to always. Deleting all installed FF extensions has no effect either.

In other browsers on the same PC, Chrome and Edge, the cookie consent option does still work as it should on the sites mentioned. In Firefox it doesn't.

This is only happening on one PC. My latop has the same FF beta build installed and is not showing this behaviour, it still automatically shows the cookie consent pop-ups when visiting sites such as BBC.com, Youtube.com and Facebook.com.

Hello everyone,

I've been using Firefox for quite some time and I always keep a bunch of windows open throughout a few workspaces on my laptop. However, this takes up a lot of resources and looks very messy. So, I've been thinking of writing a script/extension to simply store all the open links in a window to a named list that I can, then, come back to when I need and reopen. That way, I could possibly have different lists, separated by topic and stored in a single place.

I'm sorry if there is an obvious solution for this, I saw a couple of similar questions have been asked before, but none that I could use as reference.

Thank you for your time, have a nice week!

I just upgraded my Ubuntu 18.04 to 20.04 and found that Firefox (which was working perfectly before), does not work properly. Graphics (eg. profile pics on various websites) are not displayed, buttons of websites are often missing, some websites are displayed in a weird "zoomed out" way.

With Google Chrome, I don't have these issues so it does not seem to be a Linux thing...

I already tried reinstalling Firefox, but to no avail...

Help is appreciated as I would not want to migrate away from Firefox which has worked well for me for years...

Regards!
