Thunderbird had never crashed before, but lately, after the last 2 Windows 10 updates within the last 2 weeks, it crashes. It's at 128.5.2esr, the next-to-last update.

It always crashes when I choose "About" and it starts downloading the update. It appears that it doesn't get the 1st byte before crashing. It will still say 0 bytes when it crashes.

It also crashes if I leave it running and the screen goes through the screen saver mode and turns black. Twice it crashed while I was using it.

I thought it might have something to do with the fact that I had 4,000 emails in my Inbox (is there a limit?), so I deleted many and moved many to folders. I now have just under 1,000 in my Inbox.

I also tried restarting in Troubleshoot Mode and updating, but it still crashed at 0 bytes downloaded.

Is there a way to manually download the update and apply it? I can't find it on the website.

The next thing I know to do is reinstall. Is there anything I can try before doing that? Would you suggest uninstall first or reinstall over what's here?

Thunderbird will run and retrieve messages from account, but keeps crashing after 1-2 minutes each time. There are a lot of archived emails, and 1,500+ in Inbox, but sufficient disk space on the PC.

After working fine for years, Thunderbird stopped receiving email from my POP accounts a month ago and I haven't been able to get it to work since. After weeks of experimentation and frustration, the only way I can get TB to download POP mail is to install and run it in Windows Safe Mode with networking. However, once installed in Windows Safe Mode, TB run in Windows normal mode will successfully send messages from each account.

It would take pages to describe everything I've tried, so I won't. The results of all the tweaking and updates is the system specs below.

I'm at a total loss as to what I've missed or where to look next. I would appreciate any help.

This problem started after the latest Firefox update was installed. I have looked in Thunderbird Solutions but with the only one that comes close to my problem the person was able to switch to a different profile. I don't have another profile that I can do that with. In another one the problem was solved with a bug fix in a newer version. I already have the newest version. ??? Please help.

Please add a feature to disable the unread message counter on certain folders. I don't want to see how many messages I have in the Trash folder, they're in this folder because I don't want to read them, but this counter annoys me

Hello,

I wanted to customize my Firefox new tab with a local HTML file, such as "/path/to/my/index.html". It was possible to use this workaround: https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main

Which implied a configuration file (sometimes named "autoconfig.cfg", "firefox.cfg", "local-settings.cfg" depending on the guide since the name is arbitrary) with javascript code. In the new Firefox 136, this code fails to execute due to a new API being used.

If you want to customize your new tab, follow the previous guide, but on the configuration file write this code instead:

// My new tab
try {
  const ff = {};
  ChromeUtils.defineESModuleGetters(ff, {AboutNewTab: "resource:///modules/AboutNewTab.sys.mjs"});
  ff.AboutNewTab.newTabURL = 'file:///path/to/my/index.html';
} catch (e) {ChromeUtils.reportError(e);}

Note that the file must start with a comment

Adapting the "/path/to/my/index.html" to your needs.

Thanks to @mkaply (github) on this thread https://github.com/mozilla/policy-templates/discussions/1190 for the new API method.

I post this here in case someone has the same issue, because is quite recent and hard to find on the internet.

My login to Thunderbird has suddenly stopped working. I am asked for the password for my email account on pop.gmail.com. But when I enter the password for my gmail account it fails. What can I do?

I was tracing some network activity for an unrelated issue and noticed that when FF starts up it immediately makes multiple TCP connections to livejasmin.com. I have this site blocked by the Windows Firewall and have the host file direct it to 127.0.0.1 so nothing is actually going in or out, but why is FF doing this and how can I fix whatever was done to enable this happening?

I have cleared all cookies and cache, and disabled all addons, and even started in safe mode, but regardless of what I do the very 1st connections that FF makes are always to livejasmin.com, which is obviously not a legit place for FF to be doing any of its routine updates or optimization tasks. My home page is https://google.com and the livejasmin.com connections appear before the 1st attempt to connect to google so this is clearly something malicious that found a way to get into FF early in the startup process.

I have also run 2 different scans tools on the entire computer and both found nothing. I have reviewed all the running processes and do not see anything suspicious either. I do not see this issue with Chrome or Edge, just FF which is my primary browser. All browsers are updated to the latest version as well as the WIN10 OS.

I have also removed my profile and started FF up without the profile, and I noticed the livejasmin.com connections again while the FF "your profile cannot be found" error message popped up. When I had FF make a new profile and set it as the default the same connections to livejasmin.com were made when I restarted FF with the new profile. So it is not tied to my profile.

When I load the video the page loads like normal, all comments and everything is there except the video square is not there. cant see the video, anyhow. even if i move my mouse cursor on it on the start page, the little video wont play the preview. no video player at all. anywhere.

I just reinstalled Windows and then Thunderbird. I'm getting the list of messages but no message preview pane as I'm accustomed to. I found out I can hit the F8 and turn it on/off, but it appears to the side. I like it underneath the message list. I see instructions to click on the "View" to set it up, but I cannot find where this alleged "View" menu item is. I've tried to find it in Settings with no success. Please help me get my message preview pane back as it was in the bottom portion of the screen.

Thanks

I came into my home office this morning and started my Windows 10 machine from scratch (cold boot). I loaded Thunderbird and read and deleted some email. Then I went to enter a Task in the same calendar I always install Tasks in and it won't let me enter a new Task at all. The input field tells me to select a calendar that supports tasks. Well, I have! I open the Events and Messages menu option and the Enter Task command is grayed out. What the heck is going on? How can I get the ability to enter Tasks back?

I'm getting a little tired of dealing with all the issues in Thunderbird. I have spent hours trying to debug this with no success.

Hello! I am developing an application for an organization that uses Thunderbird in a Windows environment. Among other features, it is necessary to implement the transfer of mail client settings from one workstation to another. Built-in Mozilla Thunderbird tools are not suitable. I am still considering implementation options (autoconfig or direct work with files), and I have several questions. I will be very grateful for any help. 1. What is the minimum required files in the appdata folder that I need to create (transfer) so that the profile works without errors on the new workstation? No need to transfer messages, they are all on the server, and offline work is not used 2. How does the installs.ini file work? I need to avoid creating a new profile when starting Thunderbird for the first time, do I need to create an entry in installs.ini, and if so, where can I get the correct installation code? 3. Is it possible to transfer saved passwords to a new workstation? What are the requirements for this? I am very grateful for any answers

If this is possible, how do I create filters for incoming emails from specific writers and/or subjects to go directly to specific folder/sub-folders? (I'm looking through the info here, but haven't come across this.)
