I-Firefox Community Forum

I encounter a bug, which youtube website still loads normally. The problem occur when I tried to open one of the youtube video and it just a black box with no normally youtube playback button, but the recommendation can be view as I scroll further down. Entering in-video mode, cause it to going back previous page but no small video playback at the corner.

Normally, I would think my internet was a bit slower, but opening youtube in chrome or other browsing software have no such problem. I try watching Netflix on firefox, and it just works fine but the youtube things still occur.

Thank you.

dunno if this is the right board, but here goes...

I discovered a bug with Firefox and the pen/touchscreen on my lenovo X1 tablet.

Using the touchscreen, move the map, map works as it should. Can pinch to zoom, ect.

Switch to the pen, map works with pen.

Touch the screen again and Google maps doesn't respond to touchscreen anymore, only the pen, and refresh does not fix it. I have to close and re-open maps in a new tab.

In chrome, this does not happen. Only in Firefox.

I've been using Firefox in Windows for years as my default browser. Suddenly tonight, Microsoft Edge became my default. When I go into Windows Settings and try to change back to Firefox, Windows offers me only Microsoft browsers as alternatives (or offers to let me into the Microsoft Store): Windows Edge or Internet Explorer.

The Control Panel / Settings page "Set Default Apps" is the only way that I know that Windows lets users set default browsers, but it suddenly seems to be restricting me to only MS browsers.

Firefox works normally in every other way, but warns me now every time I launch it that I have a different default browser. When I click the button in the warning (or in Firefox's Tools / Settings) I just get put back to the Windows "Set Default Apps" page, which, again, only lets me choose Microsoft browsers.

What could have happened? I haven't altered my Firefox configuration or installed extensions or plug-ins in a long time. If I uninstall & reinnstall Firefox, will I lose my many configuration & interface settings and will I have to reinstall all my extensions -- or will the reinstalled Firefox remember its existing configuration? Or would that probably not help at all.

I'm very computer-savvy, but have run out of ideas. Can you help??

Hi

When I browse to https://earthobservatory.nasa.gov/images/154162/clouds-hover-over-the-alaska-peninsula, I can play the shown video once.

When the video is about to start the 2nd time though, the log from the web developer tool says (see screenshot): ``` Media resource https://eoimages.gsfc.nasa.gov/images/imagerecords/154000/154162/ak_cloudwave_vir_20250407_anim.mp4 could not be decoded. clouds-hover-over-the-alaska-peninsula All candidate resources failed to load. Media load paused. clouds-hover-over-the-alaska-peninsula Media resource https://eoimages.gsfc.nasa.gov/images/imagerecords/154000/154162/ak_cloudwave_vir_20250407_anim.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) Details: virtual RefPtr<MediaDataDecoder::DecodePromise> mozilla::GMPVideoDecoder::Decode(MediaRawData *): mGMP not initialized ``` and the video shows the warning "No video with supported format and MIME type found.", although the video was successfully played the 1st time.

Note that the first four warnings in the screenshot already appear when loading the page, i.e. before playing the video the 1st time.

The same happens when all installed firefox plugins are disabled.

I am using firefox 137.0.1 (64 bit) on arch linux.

Thanks for help, Chris

I am using the latest version of Firefox and I can not log on to facebook.com and I get a graphic with Oops somthing went wrong (see image). This has started happening in the last couple of days since I updated Firefox..

I can login in Chrome without a problem I have disabled all add ons My cache has been cleared My history is removed when I exit Firefox. I have not changed any firewall settings.

Is anyone else having this problem?

I cannot tile my Firefox windows to left or right when I choose vertical tabs mode from settings. It works fine with horizontal tabs enabled. I am using Firefox 137.0.1 on Linux Mint 22.1 Cinnamon 6.4.8 with Linux Kernel version 6.8.0-57-generic, display server X11.

Hello,

I'm experiencing a visual issue when typing in text input fields (such as input boxes or textareas) in Firefox. While typing, a dark overlay or block appears behind the current word or text I'm typing, which makes it very hard to read. It looks like some kind of highlight or shadow, possibly related to spellcheck or text recognition.

This issue occurs across different websites and makes it uncomfortable to type for long periods. I'm currently using Firefox [137.0.2] on Windows 10.

I've attached a screenshot that shows the problem clearly.

Things I've tried so far: - Disabling spellcheck - Changing themes - Disabling extensions - Testing in private window

None of these solved the issue.

Notably, switching to the **light theme** makes the issue disappear — the text input background becomes clear and easy to read again. However, I prefer to use the **dark theme**, so I’m looking for a solution that works in dark mode as well.

Can anyone help identify what's causing this or suggest a way to disable this effect while keeping the dark theme?

Thanks in advance!

My issue is that if I access the upper right corner of the screen, titled "Open Application Menu" and go to Settings I'm told my Browser is not the default AFTER THE PROCESS OF JUST MAKING IT THE DEFAULT.

It seems there is an effort to try and drive all of us nuts. This never happened before, and if it continues it will be the end of electronic communications (which it is suspected is the plan by those who engage in violence to achieve their objectives).

What I came here for was to have my settings, after the process (done many times previously) show a response in Settings that, "Yes" my browser (Firefox) is the default, which it did for a time today. Obviously there is no persistence.

When I got help on this issue previously, my response was I already tried that, and it didn't work. There used to be a lot of different browsers. Now I haven't come across any of them currently. Some are having great success in seeing to it that only their browser will survive. That seems like a "gangland" type of mentality to me.link text I believe I spent enough of my time on this issue and explained it in detail. There's really nothing else I can "contribute".

I, by the way, went to my Internet provider today who found an email under Preferences that she said had the capability to steel my emails. It had an extension in Australia (*.AU). If that has anything to do with this problem I'd like to buy a pair of handcuffs to see if that individual(s) being constrained from using a PC keyboard is a cure for this problem.

I was previously able to log into my Frontier Communications account using a normal window. Then I could not log-in using a normal window or private window. Now I still cannot log in using a normal window but can log-in using a private window. I have tried various resolutions with no results. See the below screen for the error that I receive. Suggestions welcomes.

The following is what happens when I try to logon to AT&T Yahoo mail/Currently.com "Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over."

I use Gmail, and when I receive a newsletter from the local government, Gmail does not display the images in the newsletter. I've set Gmail to display the images (photographs), so I'm guessing Firefox must have a setting that is blocking the display?

Hello

With the new update to Firefox v137 I am no longer able to sign in to Government sites using my bank as a sign in partner. Google Chrome will sign in so it has something to do with the new update. I have cleared cache and all data and still no luck with the sign in. Any help would be appreciated because Firefox has been my default browser for years and I'm not interested in changing.

Regards

When I try to log into ssa.gov I get a Bad Request error. Every time, no matter how I access the website. Only have and use FireFox on my Windows 8.1 desktop computer with Malwarebytes. No problems with other sites. I've read what seemed relevant to my question on this forum, but nothing seems to fit. Thanks, Bernadine

Hi! I have been using youtube and all of a sudden, without me restarting firefox I'm loading a video and it shows this blank screen in place of the reader. The shortcut for full screen mode is not working and other shortcuts don't do much. I've tried some options like disabling every add-ons including Ublock origin and restarting, also disabled hardware acceleration and restarted, checking for firefox updates, and I think that's all I came up with. I tried to do researches online but couldn't find something that looked exactly like my problem. I still followed most of their troubleshooting.

As you can see on this screenshot the add-ons are disabled. The rest of the page works fine, even the comments. It's just the video, as if the reader was not there. Also to note that the videos accessed since this problem appeared are not in my youtube history, as if they were never read.

Have a good day

Firefox now has a dark background on a "simple" html page without css styling (see screenshot #1). You may reproduce this issue by browsing to a local page like http://localhost:8080 with something like a 404-page (see screenshot #2)

That far - dark mode is cool, isn't it? Yep, it would be. If the text would not be black, on a dark background.

Happens to me without any plugins, or any userChrome etc. (Screenshot was taken with plugins on, but disabling them (and restarting) had no effect)

Workarounds discovered: - set `layout.css.prefers-color-scheme.content-override` to 1 (This changes nearly everything to white, which is not what I want.

- Setting theme to the builtin white/light works, but:

    - View Source has white text on white background (see screenshot #3)
    - Everything is in light mode, and thats simply not what I want

What I would expect: - Viewing a page without shitty modifications - Viewing a white page (suprise suprise) white

The latest firefox browser for windows desktop pc broke the ability to log in to at&t (also called yahoo) email. The email works fine on microsoft edge and chrome. It worked fine on firefox until the last update.
