I am facing issue with one of my email id.. It is giving me error to check authentication again.. It was working fine till Friday EOD.. But its suddenlly stopped working.. It is working fine for my other accounts..

I have been getting this error for about a week - absolutelyu no changes have been made to my usual use of the PC and browser. There may have been Firefox/Windows updates installed. I'm not doing anything different to the usual work I do.

I have tried using a new Firefox profile with no cached info carried over, this doesn't solve the problem. I have no extensions or add ons. I do run Avast, but haven't had this problem before.

Crash report: https://crash-stats.mozilla.org/report/index/1fe71926-ad8e-4592-b103-9874f0250722#tab-annotations

NB: I do not usually get the opportunity to submit a crash report when these crashes happen.

Recently asked by Mozilla Thunderbird for access to my data etc and this was questioned by Google. However I agreed to the request and wish to be assured that this was not a scam

I have HDR working in Proton games and mpv fine (using Plasma 6.4 / Wayland)

I enabled HDR in Firefox (gfx.wayland.hdr), and HDR content works in YouTube fine ( looks amazing!) however.. I have an issue in that all non HDR content doesn’t show any video (I have sound) just a green sceen (see screen shot) including all ads.

Any idea how to work round this ?

I have AMD 7800 GPU .

Cheers

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

I requested my Pocket export three times in June '25 and have received nothing. (Most recent request on 24th June '25, ID: 25174602-3e81-421e-a30d-71ff91dd2d66

I have also contacted Mozilla Support using the contact form twice to raise this issue and didn't receive any confirmation of those support requests to my email address.

The only possible explanation that I can think of is that maybe there has been a problem at the time when Mozilla acquired Pocket and I linked my Pocket account with my Mozilla account. I had previously used a different email address for my Pocket account prior to 2017. I currently have two email addresses (primary and secondary) associated with my Mozilla account but none of these email addresses are showing up in my Pocket settings, only my username. My Mozilla account is the only place where I can see my email addresses listed in my account details but I can't understand why I didn't get the confirmation emails to my Mozilla Support requests.

I used Pocket extensively for work so I really need to get the export. I'd really appreciate some help, thank you.

Hello,

After updating Mozilla Thunderbird to the latest version, I’ve encountered two significant issues across multiple computers running Windows 11 PRO:

• Missing unread message indicator – Upon receiving new messages, there is no red marker showing on the Thunderbird icon in the taskbar. This makes it difficult to quickly identify unread emails without opening the application.

• Email links not opening new message window – Clicking on an email address (e.g. in a browser or another program) no longer opens a new message window in Thunderbird, as it used to.

Both issues have been observed on different machines, which suggests they are not caused by specific local configurations.

I’d appreciate it if you could let me know whether solutions for these issues are available or if an update is planned to address them.

Kind regards, Maciek

День добрый! Был архив почты, который всегда открывался. Сегодня почта пуста, нет писем и ничего более. Проблема вся в том, что я когда-то работал в компании, которая уже закрылась и больше не работает, а почту использовал как базу данных. Теперь у меня нет доступа не к почте, не к базе данных. Что делать в такой ситуации?

I do not like the latest version. I used to be able to tap on "Get all new messages for all accounts" (or similar) and I would get all messages for my 5 accounts. Now I need to tap on the thunder cloud image and then tap on the Inbox for each of my addresses. So much more work involved. Not happy!

I don’t see the “Open in Conversation” option when I right-click a message. It simply doesn’t appear. Also in the Message menu on the toolbar, the “Open in Conversation” is missing too.

Interestingly, if I click on something like “1 reply” to expand the thread, then right-click one of the messages inside, I do get options like “Open Message in New Tab” or “Open Message in New Window” but still no “Open in Conversation”

I’m using Thunderbird version 140.0.1 on Windows 11

Thanks

Is it just me or is Thunderbird not a particularly polished product? It's been around for years and by now one would think it would be so 5 star cutting edge that no other client could possibly touch it. In my experience, not so.

I had TBird many years ago and then became an early adopter of cloud based email. I used the provider's interface. I now use three email providers and thought that going back to TBird would help me concatonate all of my accounts in one easy interface. While it has done that, why has it taken so long to configure?

i'm an expert user. I always configure my accounts manually with non-default ports, etc,... I know what I'm doing. It took me a few hours to figure out how to configure them all in TBird AND make them work. I should have been able to have all accounts setup and operational in 15 minutes or less. What I'm finding is that TBird functionality is not very intuitive. I've even had to resort to doing online searches to find out how to do things. That does not speak well for what should be a very mature product. It's not as if Mozilla does not have resources to develop a professional product. It seems that they let the product be developed and then forget about quality control and gaining user feedback with focus groups. if they did this, TBird would be known as very mature AND POLISHED!

Another area I'm having nothing but issues is the calendar. Like email it should be an easy process to connect Tbird's (app) calendar with an external calendar and have it operate two way. I've been trying to connect my TBird calendar with Apple calendar so that I can have a reliable calendar on my iPhone. I wouldn't have to do this if there was a TBird iOS calendar app. The fact is that two weeks later and I'm still putzing around with it trying to make them talk to each other. The online help is virtually useless. There is a lot of old information. How do I know this? The instructions say to look for something and then that something is not in the current version of TBird. Then I have to go at it solo and try to figure it out.

Also, I find the TBird interface a little dated but more important not at all intuitive. Trying to do simple things like compose a new message takes time to figure out. Yes, I finally found the "Ctrl N" command, however, I am now so accustomed to graphics interfaces that I resist going back to Ctrl keyboard commands. I'm not new at this game, I've been around PC's since the original IBM PC that ran IBM-DOS so command lines and keyboard commands are nothing new to me. I simply don't want to use them any more. TBird forces me to do that. It's as if the developers are all stuck in the 80's-90's and don't really want to take this product into the 21st Century.

Don't get me wrong, it's a very good product from the back end, however, I have distaste for anything that forces me to change my workflow and that is what has happened. I don't mind making some changes, however, going back to TBird makes me feel as if I'm starting all over learning about email and calendars. I'm a professional. At one time I enjoyed hacking and making things work the way I wanted. Those days are gone and now I need tools that work out of the box as I value my time.

Tbird needs is a LOT OF SPIT AND POLISH for it to be regarded as a product that can be used easily by professionals, neopites and everyone in between. At this time, it doesn't hit that mark.

Hi there. I tried to connect to a library WiFi which required to enter a username and password in a login form to have Internet access. First of all, the firefox could not open the login page normally (automatically). I had to check the Gateway IP address of the WiFi connection and find the login page manually (same problem with chrome). But when I tried to submit the login form, I got "Secure connection failed" error in my firefox (PR_END_OF_FILE_ERROR). Then I tried chrome and the form submision worked fine. I experienced this same problem both on Windows 10 and Debian 12 (could not submit the form on firefox, but it worked on chrome), so the network setting misconfiguration scenario is unlikely. I also read the mozilla page related to the error but it was not helpful. What is the problem and how could it be solved?

For the past 2 months I've found it very difficult to sign into my Hotmail account using Firefox. Microsoft keep telling me to use a VPN or another device. I like answering emails on my computer because of its large screen. I've tried signing in about 2000 times now. Firefox told me they can't help me because I'm not a Mozilla subscriber even though they own Firefox. Microsoft told me it's Mozilla's problem. Can anyone help me please. John in the Philippines.

Whenever I watch a video in full screen the notification bar doesn't go away. It stays on one side of the screen as a grayed out bar. I've tried uninstalling Firefox on my phone & installing once again, clearing cache, logging in & out of my account, even clearing my settings & redoing everything one by one but nothing works. This issue persists on all websites when the video is in full screen mode.
