Had to replace FF with Chrome in order to play DRM content on my W11 laptop. I get message saying you are downloading remedy, but nothing ever changes. Would prefer to continue 15+ year relationship with FF, but seems like youre abandoning capabilities for DRM video content?

TB no longer will start. It just hangs and when I go to it on my Mac I see a spinning disk. That never changes and eventually, after hours, I must force quit and report it to Apple. I receive no messages or error codes.

When I open firefox in ubuntu linux. (WSLg) Fresh install. I can't go to settings in firefox. Steps: press the hamburger menu, press settings, nothing happens.

OS: Ubuntu 22.04.4 LTS on Windows 10 x86_64 Kernel: 5.15.146.1-microsoft-standard-WSL2 Shell: bash 5.1.16

In firefox Ubuntu (WSLg) the dropdown menus don't work. I have already tried reinstalling both firefox, and the entire OS.

When I press Custom URLs... (see image) nothing happens. This issue is everywhere in the brouwser, on websites, even when I press help in the hamburger menu. (Or settings in that same hamburger menu.)

OS: Ubuntu 22.04.4 LTS on Windows 10 x86_64 Kernel: 5.15.146.1-microsoft-standard-WSL2 Shell: bash 5.1.16

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

I am no longer able to add attachments to gmail or upload images or attachments to websites. When I click on the attachment icon or upload button, my finder window does not open. However, it works in other browsers. How can I fix this?

What the title says. While I was doing school work my session crashed and I lost all of my work. Upon reopening Firefox I was told my browser had installed the latest update for Windows. I then checked my crash logs and saw my session had crashed and Firefox had installed the update. Why could have this been? I would like a solution to this to ensure this doesn't haven't happen again. Thanks.

I have read the thread for this similar problems, tried all the suggestions but I'm Still experiencing videos not staying full-screen. Is there any other solution to it? This has started since yesterday but everything was fine before then.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

Since the latest upgrade to 115.10.1 (64-bit) I have an issue about running Thunderbird.

From a clean Windows 11 start up it is OK but then if I then Exit and then try to run the bird again it does not start.

Digging around I discovered using Task Manager, a number of Thunderbird processes run after I had Exited. See attached.

Any thoughts?

Download files (pdf, xml) don't open in application (acrobat, firefox) since 125.0.1 Firefox version from IBM Power server with Ubuntu :

The message is "Fichier non téléchargé - Risque de sécurité potentiel" that is "No downloaded file, potential security risk" :

When we download a pdf file from the server, the "choice box" allow to . open in the browser or . open in Acrobat or . download on my PC. The opening fails with this message. This is the problem. The download on my PC works and when I open the file from my PC it works also.

We need this function of opening a pdf or xml directly from a server IBM Power with Ubuntu. It was OK for several years until 125.0.1 Firefox version. We had no change on the IBM server.

Can you repair this problem quickly. My PC uses Windows 10

Thank you Patrice Castejon [removed phone#]

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

Every time I open TB email on my laptop I get the following page, which then exists as long as I am on TB. I can work-around this page to send and receive email. Here is the top half of the page:

Mozilla Thunderbird Email wants to access your Google Account undefined jschoolnews@gmail.com This will allow Mozilla Thunderbird Email to: More info Read, compose, send, and permanently delete all your email from Gmail

                      (the same for contacts and calendars)

I reinstalled the Visual C++ and Firefox loaded when i ran the Firefox repair but totally locked up. Unable to get to settings or any website and will not run after closing it.

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

An IMAP mail system is configured on a server running Debian 12. While there are never any problems via webmail, reception and sending work occasionally via Thunderbird 115.9. Even in "Troubleshooting Mode" it doesn't work. The server has good hardware characteristics and there are no applications that can slow it down, nor do I think it is a firewall problem or incorrect parameters otherwise it would never work. The error is related to timeout reaching the server. What can I check to find out where the problem is?

Picture-in-picture since recent YouTube update keeps closing. Is there way i could configure in about:config to never close and always stay open even if page refreshes and have it move the video play back always to the Picture-in-picture window ? If not could this be made a feature in a future update ?

YouTube especially been annoying to Firefox users, cos it keeps refreshing the whole page breaking stuff every time it plays the video, as well have issues with looping videos even tho they are already fully buffered, making entire YouTube experience as frustrating as possible as encouragement to switch to chrome, which i refuse for obvious reasons.

Anything i can do on my end ? If tested if this happens in incognito mode as well with all extensions disabled in private windows, no change of behavior.

Btw this happens on the new YouTube interface with no way to get back to the old interface, cos it keeps the annoying features of the old interface even if you try to re position stuff using hacky ways like extensions that do so, which of course break stuff even further. I just want Picture-in-picture to remain open, and to play current video in picture-in-picture that is playing automatically.

Btw the Picture-in-picture experience with chrome or chrome based browsers is absolutely horrible, giving me even more reasons to stay on Firefox besides privacy related issues and other issues.

So I'll be typing like normal (I type 100 WPM), and all of a sudden, I'll type a sentence, but each individual letter starts taking about 3 seconds to show up on the screen. I have to sit and wait a super long time for everything I typed to finally show up. Other times, I move my mouse over something I should be able to click on, and have to wait a long time for the arrow to turn into a hand, letting me click on it. These periods of slowness will last a few minutes, then disappear.

What's really interesting is that when the slowness starts, I can type just fine up in the URL bar. I might type my entire message there, then copy paste it down to where ever I was wanting to post it. However, when I do that, if I have another tab open and that tab is playing music, the music will start to break up and lag as I type. Again, after a while, the slowness disappears and we're back to normal.

Can anyone tell me what's going on?

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it. It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.
