Why does FireFox not allow me to play videos in Youtube above the resolution 360p. Since now FireFox won't allow me to play YouTube videos from 720p or 1080p anymore. While other browser's allow me to play above 360p up to 4K resolution. What is going on with FireFox this never happen before until the upgrade of FireFox in Manajaro ARM.

I'm running version 118.02.2 (64-bit) of Firefox on Windows 12. I *always* have the 'Open previous windows and tabs' checked. Starting yesterday, Firefox opens with nothing other than a blank page. Luckily for me, this has happened in the past and I have a Bookmarks Menu folder with my default tabs saved. Even so, it's still frustrating.

I'm encountering consistent video playback issues on Firefox while running Fedora 38. The error message I receive when attempting to play videos from certain sites, notably LinkedIn and Twitter (now X), is:

• The media playback was aborted due to a corruption problem or because the media used features your browser did not support.*

Furthermore, when examining Firefox's console while attempting to play a video, I observed the following error:

• [Child 5999, MediaDecoderStateMachine #1] WARNING: Decoder=7fdb3c55a100 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-118.0/dom/media/MediaDecoderStateMachineBase.cpp:166*

Steps to Reproduce: 1. Navigate to LinkedIn or X (previously Twitter). 2. Attempt to play any video content. 3. Observe the aforementioned error.

Additional Details: - OS: Fedora 38 - Firefox version: Initially 117.0.1, then updated to 118, both 64-bit. - This issue does not occur on Google Chrome on the same system. - I have attempted the following troubleshooting steps without success:

 1. Updated Firefox to the latest version.
 2. Enabled DRM content.
 3. Booted Firefox in Safe Mode.
 4. Disabled hardware acceleration.
 5. Cleared cache and cookies.
 6. Used a Flatpak version of Firefox.

This issue has significantly impacted my user experience, and I hope to find a resolution soon. Any assistance or guidance would be greatly appreciated.

Thank you!

"Container Tabs" are unavailable in Firefox on my employer's corporate PC. The "Enable Container Tabs" option is missing in the Tab section in Settings. There is a notification "Your browser is being managed by your organization." Thus, the lack of container tabs may be due to corporate policy. However, I don't see anything on the Active Policies page except one irrelevant record: "InstallAddonsPermission Default false." Additionally, "Container Tabs" are unavailable only in Firefox. Nightly has them. But, Nightly is not officially supported by my company. I have tested several corporate PC and different versions of Firefox and Nightly. Is it a weird Firefox bug or something else?

I have the same issue as this guy https://support.mozilla.org/en-US/questions/1402931#question-reply Exceptions. I have a new Dell pc and my Mozilla browser is 118. I have had this issue from the time that I purchased the new pc and attached it to my old Dell monitor. I've had Dell and Geek Squad involved both before and after I found this guy's fix in the Mozilla faq's. Before finding that I have had the new pc checked, the old and new monitor checked. All turned out fine system wise. So first suggestion from Dell - new cord - HDMI to VGA - didn't help. New monitor. Didn't help. Finally after much purchasing of technology and no changes a Dell tech was on using Edge browser. I realized that the monitor was perfect and told them so. So they tried Chrome and still the monitor text was fine. Firefox - back to blotchy. That's when I did the search in Mozilla faq's and found this other issue and "fix". I talked a Geek Squad tech into changing my display setting to "Extend Display" in Windows. Text totally disappeared from the monitor. So I've run out of options other than to set up everything under Chrome or Edge which I really don't want to do. But I may have to. In the meantime I've proved that I didn't need a new monitor or a new cord.

The image below is a camera picture of text on the monitor.

Help!!!

this is a relatively new issue. I have been using the combination of firefox to Commbak and Xero for 10 years. it is only the last couple of months that I have been encountering this.

I couldn't find a category for Firefox accounts/Mozilla accounts, so this question will be posted in the Firefox forum.

TL;DR Is there any way to get in touch with someone at Mozilla who can correct a faulty notification email address for a Firefox/Mozilla account?

My best guess is that when I first created the Mozilla account, I used the Gmail address, and even after changing the primary and secondary email addresses for the account, the Gmail address still remains somewhere in some database in the backend and it can't be removed or changed by an end user. Is there any way Mozilla can fix this issue?

The full story

Today I received an email introducing the renaming of Firefox account to Mozilla account. The email was sent to my old Gmail address even though I've changed both the primary and secondary email address in my Mozilla account settings a long time ago.

Email notifications about sign-ins and/or changes that are made to the Mozilla account are sent to the correct email addresses that I've configured in the account. So the issue is with general announcement emails regarding Mozilla accounts.

I have not received the email about the Mozilla account renaming to the email addresses that are configured in the account. Somewhere down the line I will delete the Gmail account, but that will also mean that I won't get these kind of announcements and thereby risk missing important information regarding the account.

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.

Up through Monday, 10-16-2023, I could play Amazon Prime Videos. As of Tuesday, 10-17, I no longer can. I can do this on other browsers, e.g. Chrome and Safari. Can this be fixed or do I need to stop using Firefox?

On upgrading to Firefox ver 118.02, I cannot get any toolbar icons to appear in their correct place on the bookmarks toolbar. Instead they are crammed in the middle of the second (address) line. The double chevrons can be used to access the remaining of the toolbar icons.

Dragging a link to the toolbar space is not allowed.

Please fix this. I need easy access to ALL my toolbar icons, and have an expanded search box on the second line.

In trying to use features of various apps, the app tries to connect to Firefox, resulting in an error message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." But in fact, Firefox IS running. An example of this problem is invoking updates of some apps; another is in Zoom trying to login using SSO. It leaves me stuck, and the only solution I have found is to use Edge instead of Firefox.

I need to shrink the size of my tabs, which remains constant no matter how many are open. If I have four open, I get the "+" for a new tab at the end of the tab bar. If there are five open, the tabs consume the entire width of the browser window and the "+" sign disappears. It is not found in the "customize toolbar" menu. I have tried restoring tool bar defaults and changing the uidensity to 1, but neither change shrinks the size of the tabs or gives me the "+" option.

What do I need to do to get back to the way it used to work?

When I updated to Ff 118.0.2 on Ubuntu 22.04.3 LTS today 4 out of 7 windows disappeared. When I upgarded Ubuntu from 21.something four days ago 6 out of 9 windows disappeared. Can I get them back or do I have to stop upgrading?

as of 2023/09/29 hulu, netflix, prime and disney+ are not playing videos on firefox, after making zero changes to settings or configuration.

I tested Netflix on Google Chrome and videos played, confirming this is a Firefox issue. I cleared recent/all history and changed passwords for those sites. Netflix logs me out if I attempt to play content. Speedtest reports 200 mb/s. Mozilla VPN is installed but turned off. Netflix sign in reports a new device/login in my state which is different from the VPN setting so this confirms that the VPN is not active and blocking content. HBO/Max videos play correctly and that site does not have the same issues. Firefox has crashed numerous times in the last two weeks. Sometimes just a single tab, sometimes a full application insta-quit.

I prefer to compartmentalize usage across different browsers for privacy/security reasons and would like to continue to use Firefox for these streaming services.

Hello! Since I updated Firefox to 118.0.1 (latest version when writing this) the Teams Large Gallery mode in Firefox is displaying black and eventually all the participants appear but the performance is 1 frame per minute. All the cameras are frozen and occasionally the display refreshes for one single frame.

Audio is working fine and default Gallery mode (only 4 camera displayed) still works normally.

Thank you!

The default location of the new bookmark is set in about:config，that is browser.bookmarks.defaultLocation. How can i change it with JavaScript in third-party extensions？

I am running Firefox 118.0.2 64 bit on windows 10 22H2. For one particular website I get a 403 error on Firefox, the site opens normally on Edge. I do not have any add ons or extensions that block websites. I have cleared cache and cookies and tried to open the site in troubleshooting mode, no luck. I have also disabled BitDefender, same results. Any suggestions are appreciated.

I'm no longer able to log in to BankofAmerica.com using Firefox but can do so with Chrome. BofA tells me that Firefox is most likely put a block that isn't showing up. Can you remove that block or tell me where to find the block to all Bank of America to log in to my account?
