I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

Hello. I would like tell about a problem. Before the icon was black, but now it is WHITE. it’s so ugly! I wanna change it to black color. how I can do it? I don’t want to do it through “shortcuts” because it sands me notifications. I hope that you will add this possibility or already it is possible. заранее спасибо!

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

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.

Is there a possibility to keep the tabs at the top while in full-screen mode, or make it an option? As I need tabs but work best in full-screen mode so windows is pushed to the side.

I exported my profile to an external drive, then reset my Windows 11 PC. The resulting file is a zip file. When I import, the import starts, then stalls and gives an error. The error log is incomprehensible to me. How can I not lose my local folders and messages? I tried unzipping and importing that folder, but another error. I need help! Ideas? Thanks.

Hello, when I try to login to my outlook.cz mail account, I get error screen that says: Server error The server returned the following message: User is authenticated but not connected. I searched online and I found, that I wasn't the only one getting this error. Everyone solved it by disabling ipv6 in thunderbird. I don't know how to do that on phone (I found how to disable it on pc). I have another outlook.cz account that I am logged into and it works fine (I logged in 2 weeks ago). Is it thunderbird problem or should I contact microsoft. Thank you in advance for your answers.

Not having used the desktop Thunderbird in a while I went through and updated passwords when prompted while trying to access emails and it downloads ok but will not send. I get an error message that states log-in to server failed but it's substituting/listing a very old email account/address that is not even list in my current account list.

I followed another thread and searched for prefs.js files and there is only one. Should I delete that or is it even the issue?

I'm getting junk mail that uses my wife name as the sender. My wife died a year ago and I do not like seeing her name being used this way. Basically, the email (fake billing) has: her name as the sender my email address real sender address (junk/spam name from gmail).

I need to have any email as she being the sender to automatically go to junk and trash.

Please, tell me how I can do this. I'm getting up there in years, so any help and a "how-to do it", I would really appreciate it very much.

I was not able to "see" any way within Thunderbird on how I can do it. BTW- the version of Thunderbird is: 128.9.1esr (64-bit) and my OS is Ubuntu 24.10

Thank you for your time.

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

I want to 'Import bookmarks, passwords, history, and autofill data into Firefox' - from an Extreme SSD, used as a Time Machine on my iMac.

I had to do a clean install on my iMac = due to a problem with the latest OS system update Sequoia. And have so far been UNABLE to import either 'Passwords from CSV file' or Bookmarks from HTML file'.

Thank you!
