I am using Windows 10 Enterprise N, Version 21H2 and installed the Media Feature Pack through the Optional Features tab. But even though other browsers have picked up on that and can play e.g. Twitch streams etc. appropriately, while Firefox still shows the `this video is unavailable or not supported in this browser` error message.

Hi there,

I upgraded my Mac Desktop OS to Ventura 13 yesterday and now my Firefox browser is not working. It opens very briefly and then the window closes immediately. The Firefox program is still open in my dock, but when I click on the icon, the Firefox window only opens for the briefest moment and then immediately closes again.

I tried to fix it: I have uninstalled and re-installed the latest version of Firefox twice and have rebooted my computer twice.

Has anyone has similar experiences and/or ideas for solutions?

Thank you!

People are having connection issues on firefox https://www.reddit.com/r/firefox/comments/x1um0o/browser_problems_after_1040_and_10401/

A fix for this is going to about:config

network.dns.disableIPv6 and set to true

Disabling ipv6 is a fix, but is this safe?

I think mozilla team should look into what exactly is making ipv6 cause connection issues.

Thunderbird is suddenly no longer able to retrieve emails from my accounts at my hosting service. No error messages are shown; the program simply does not retrieve messages automatically any longer nor does it respond in any way when I attempt to force a retrieval with "Get Messages". I am able to view the emails via browser through the provider's webmail interface.

I am using the latest version of Thunderbird (102.3.2, 32-bit) under Windows 10 Pro, version 21H2, OS build 19044.2006. I have not made any changes to Thunderbird settings.

I have my email accounts set up using the provider's POP mail server, with settings auto-detected by Thunderbird when I set up the accounts. Port setting is 110, connection security is set to STARTTLS, and authentication method is "Normal password".

Many thanks for any troubleshooting suggestions.

I have received an email from Talktalk explaining that they will be making changes to the system in October and giving different email app settings. I use Thunderbird and I made what I think are the recommended changes including changing the incoming mail settings to mail.talktalk.net. I have tried to verify the changes and use Thunderbird but I now find that I can get no further as I am asked to 'Enter your password for 'aparr17@talk.net' on 'mailtalktalk.net' I am subsequently advised that 'Log in to servermail.talktalk.net with user name aparr17 @talktalk.net' failed and asked to enter a new password. Needless to say I can get no further and as I would like to continue to use Thunderbird after Talktalk have made the changes can you advise me how to get further forward with Thunderbird and the changed settings.

I've recently been having troubles playing videos on Firefox.

My school website uses Vimeo embeds, but recently when I've put the videos in fullscreen, after 4-5 seconds it stops responding. The video freezes but the audio continues, and the controls don't come up when I move the mouse. I can press ESC to exit fullscreen, but the controls are still gone and the audio keeps playing. Then after a few more seconds I get the warning "This page is slowing down Firefox, to speed up your browser stop this page".

If I don't use fullscreen but instead zoom in on the page, it also freezes. If I try the same things with Edge it does not freeze. I also made sure that it was only affecting Vimeo videos, by testing with other platforms and other vimeo links.

I found previous reports of this issue, but all of them were either on Linux, or it was an issue with flash player, which is not relevant anymore.

Not quite sure how to debug this but I would be happy to provide further info. It's really important that it works again :/ Thanks in advance!

My repro steps: 1. Find a video on https://vimeo.com/watch 2. Play it and enter fullscreen 3. Wait around 6 seconds

I seem to have that bug that was fixed a few updates ago where videos won't play. I have the latest version of Firefox. For example, YouTube will load and the page, progress bar and even subtitles will show, but the video will just have the spinning circle. I have tried videos on other websites (Facebook, Tumblr) and they won't play either.

I've uninstalled/reinstalled Firefox, refreshed Firefox, disabled all add-ons, allowed autoplay of videos/audio but nothing works. The videos all work on Chrome and Edge.

Good morning. I use thunderbird with a 365 account to manage my mail. I set the option "mail.server.default.check_all_folders_for_new" to true to get all folders when I refresh the email. The problem is that at startup I get an error saying "the current operation on [FOLDER] did not succeed the mail server for account [ACCOUNT] responded [FOLDER] doesn't exist" (see screenshot). I got it for several folders. The problem is that these folders are all deleted or renamed folder that doesn't exist in 365 and if I go to account > subscribe these folder doesn't exist. My guess is that internally thunderbird saved the old folder to be refreshed and never removed it. Is there a way to fix this problem? Thanks

Yo guys what's up! Been having problems with Firefox for several months now, restarts make no difference. Getting huge CPU drain if I have any Twitch tab running. Above screenshot is in troubleshooting mode (all my addons disabled) and a single twitch tab open. It makes my whole system sluggish especially if I happen to have something a little demanding in addition to the stream open. Chrome does NOT do this at all, much more balanced drain.

Specs:

HP pavilion laptop 16 gb ram core i7 chip bottom of the barrel nvidia mx250 GPU

The other screenshot is a comparison to Chrome. Both have a SINGLE tab open with a twitch stream playing. Firefox is using almost quadruple the resources, AND its in troubleshooting mode.

Hope you guys can help me out, been a long time Firefox user since I was a kid and really don't want to switch browsers.

The new version of Firefox runs very slowly, tabs take long time to load and is slowing down other operations on computer while waits for mouse to re-appear etc. Had downloaded a previous version, then firefox automatically updated and back into sheet mode. Now your ridiculous download previous version page is very much less than helpful as just keeps trying to get you to load newest (crap/buggy) version. Uninstalled firefox and computer works well again. I've used firefox for long time, but will change to something else if cant access a download for previous version that allows better operation while wait for a perhaps better working newer version. Learned lesson with windows updates over the years, not gonna use your current version of firefox.

I use a PC with Thunderbird and an iPhone with its mail app(Thunderbird not installed on iPhone). Approx 2 weeks ago, I found the mail icon gone from my iPhone. After dealing with Apple and Spectrum(my ISP), mail was restored but not syncing between devices. Prior to that problem, if I deleted an email on my iPhone, it disappeared on my PC, and vice versa. Now I have to manually delete on each device. How do I get back to pre-incident operation?

My tb has a long starting time after updating to ventura. It´s about 30 to 38 sec. I tryed: -deleting all caches and the startup cache -debug mode without themes and plugins -starting from terminal -tryed to start with admin rights -disabled all plugins -deleted all themes -deleted all calendars and created a default calendar -tb 109 beta

-looked for the preferences

-deleted ligthning prefs -disabled looking for proxies and disabled dns over https

at last, I tried deleting all the files in the library and started an "out of the box thunderbird". The result was - the same startup time and the same errors. Then I tried an user without icloud and the startup time was normal: less then 2 seconds!

My errors:

I love Firefox but it has a market share of just around 7% and is even lower than Edge (which is terrible IMO). Chrome has the most users at around 65%.

Although Firefox is a much better browser, the perception for many is that Chrome is better due to much faster browser loading. I have Chrome and Firefox installed on Windows 11 with the same extensions and Chrome loads my home page in 2 sec whereas Firefox takes 7 sec to load. Even after deleting all cookies, cache and web history, Firefox still takes 7 sec to load my home page.

It's great to prioritize security, flexibility etc and I love these aspects of Firefox, but by not doing something to improve the awful loading times, you are leaving users with the impression that Firefox is inferior and LOSING the browser battle.

Thunderbird 102.6.1 gets stuck checking password when adding new account. Windows 10 environment. The correct password is being used. It appears other people have experienced this problem and solutions proposed have been to remove/re-install Thunderbird, don't save or provide password when adding the account, etc. but NONE of those work here. Others have suggested this has something to do with maybe version 102 and I tend to agree with that opinion. The only way I have been able to resolve this problem is to completely remove Thunderbird 102.6.1 and then re-install an older version (e.g. 78.13.0). Then use the exact same information to add the account and it works perfectly. No kidding! So has something changed around version 102 in the way new accounts are added? Like the new account setup wizard?

At some point, after 15+ years of using Thunderbird and Hotmail, it stopped SENDING e-mail from the Hotmail account, even though it would still download new messages. Could still send messages from another ISP account. Have to save the message composed in Thunderbird then log in to the Hotmail web interface to send it. Went round and round with AVG anti-virus to see if it was blocking sending e-mail, then worked with Microsoft support. Eventually removed the Hotmail account from Thunderbird, re-added the Hotmail account to Thunderbird, and it worked, for a while. Downloading a lot of messages in IMAP, so that they stay on the Hotmail server takes a long time. Sometimes will have to close Thunderbird, then resume the downloading of messages later. Trying to send a message, when it is now FAILING again, could it be that Thunderbird is WAITING UNTIL IT HAS COMPLETELY FINISHED DOWNLOADING ALL OF THE MESSAGES in some sort of queue, before it gets back to seeing that the user is trying to SEND a message, and to process that and communicate with the Hotmail server?

Hi, For about the last month or so, the Yahoo mail tab closes itself after I click on an email attachment to open the download dialog box. This happens exactly 30 seconds after clicking on the attachment, whether or not I go on to open or save the attachment. It does not happen if I merely 'preview' the image. I don't know if all attachment types behave the same, but it applies at least to jpg and pdf files. The tab can be reinstated via History/Recently closed tabs.

Firefox does not crash, and there are no crash reports. In other respects this is similar to a previous post by 'eladopoulos' on 4/30/22, 8:17 AM (https://support.mozilla.org/en-US/questions/1375635).

Using Safe mode makes no difference. I had set browser.download.improvements_to_download_panel to False, but reseting to True makes no difference. Thanks in advance.
