I have/had two different problems with the same results. In the first case I get the login window. I enter the password hit return and that window goes away and some times you can scroll to different opened emails before it says "Not Responding". The only action that works is to exit the app. Usually after a few days or weeks it will start working and does so for a few days or weeks. Lately the login window does not appear when the app opens and it displays the "Not Responding" message. It shows that it is "Loading Message". I have tried all of the options from the troubleshooting window and reinstalled Thunderbird with no change in response> Where do I go from here?

Hello. I am back again with the same issue that I presented on the forum post three months ago. https://support.mozilla.org/en-US/questions/1594903?utm_campaign=questions-reply The difference is now it is happening on Firefox v157.0.1;everything else is identical. Qubes os R4.3.2 with Firefox 157.0.1 in a Fedora 44 xfce VM. To recap I open one window for Proxmox Datacenter Manager and as soon as I click to sign in Firefox completely disappears. I can open this in Chromium browser and Firefox ESR v.140.17.0 esr perfectly fine. Please consult the original post for all I did to troubleshoot this. I am working with the esr version now but would like to help put this issue to bed. Community members stepped up last time to help me so I am here to do my small part for others. Ask for any info you need and I'll reply ASAP. Thanks in advance. SDS

I received a message with a password-protected attachment, and opened it in Thunderbird (in Windows 11).

I found that the password I'd been sent did not work with the attachment. I inadvertently closed the Thunderbird app with the password prompt still open.

When I tried to open Thunderbird again it tried to load the attachment and then just hangs indefinitely. Using safe mode has the same result.

Please can you suggest a solution?

Thanks

Today TB froze during start up. No problems yesterday.

I deleted global-messages-db.sqlite and restarted TB. Now it is frozen with a "Loading messages". Maybe it is rebuilding indexes and this takes a long time and I should be patient.

Maybe my In and Sent mail boxes are too big? If so, how can I safely prune them?

TB is becoming increasingly unstable for me. It was very reliable before about a month ago.

I doubt my AV is the culprit because AV has not changed today.

Thank you one and all.

Persistent crashes on the android Firefox mobile app

Hello, I run Firefox mobile on a Motorola g stylus 5g, and although I'm aware it's a lower-end device, the constant crashes with the app is becoming infuriating. I'm on the newest version, and a large majority of these crashes occur when I'm on twitter browsing posts.

These crashes can happen a few minutes into browsing to an hour, and this issue used to never happen until the update before this one. I use a few extensions related to appearance, those being Ublock origin, dark reader, and control panel for twitter. Performance regarding being on the website has always been awful, but it's never crashed before.

In addition, the app is insistent on reverting me to tabs I had either an few hours ago to days ago, and it changes to what I currently had on screen for unexplainable reasons. I've tried resyncing tabs but this rarely solves the issue

Any advice in resolving these crashes would be appreciated. Attached is my crash log.
