Thunderbird Community Forum

After I upgraded my system to Kubuntu 24.04 thunderbird started eating CPU (150+% CPU usage according to htop). Because I couldn't tell if the culprit was the new KDE or the old profile, I tried to create a new profile, blow away the KDE config, etc. I also tried downloading the latest version of thunderbird from the website. Nothing helped.

I was able to replicate this problem using the in-memory, fresh KDE.

To replicate: Create Kubuntu 24.04 install USB. Boot from this USB. When asked to install or try, select "Try Kubuntu".

Start Thunderbird.

When prompted to create an account, select cancel. Go into settings, to the bottom, and select Maildir for file storage. Quit thunderbird, and start it again. Create account (select configure manually, enter the information for imap and smtp host, STARTTLS, detect authentication. My username does not contain an @, if that makes a difference). Select "Re-test"

Try to read mail. You will quickly notice that Thunderbird is consuming > 100% CPU, and UI is non-responsive.

Restarting thunderbird does not help.

netstat -tupane shows one or two connections to my imap server port 143, but wireshark doesn't show any traffic on port 143

Not that I think it matters (since I can't get Thunderbird to start seriously downloading from the server) but I have a big ( >100G) Maildir behind my courier server.

Note that I see this problem both with the version on Kubuntu 24.04 install USB, and the latest version downloaded from the thunderbird website.

I feel rather obtuse asking, but how do I get my Thunderbird addressbook to sync to gmail contacts? I uninstalled Cardbook, because Thunderbird now does CardDav, I treid to create a new CardDav addressbook by opening my addressbook, selecting new addressbook, and going through the steps to give Thunderbird access to my Google account. But,

  no new address appeared in the list of addressbooks, and 
  the option to create a new addressbook is no longer avaiable/showing.

Addressbook is still not syncing. My server settings are IMAP. I still have three address books: All, Personal, and Collected.

I am flumoxed. John

Thunderbird is not working anymore. I can start writing an email but after about 5 min it dont take any characters any more. Its lagging and does out. Its in the draft folder and I ry to open but it will not work. If I just write a short message its no problem but as soon as I start write longer messages it will be trouble. It doesnt help restarting the computor. I use win 7 and the latest version. The problem started about a week ago. Writing this is no problem but if I would do it in Thunderbird it will not work by this long in the text. Best regards Stefan stefan@besthe.se

I've tried the new thunderbird mobile. Very good indeed. Just two things missing for me. There is no way to add/delete a new folder. Second there is no way to print an email. Let me know when these points might be included.Thanks

Running 115.16.3 because I have a Windows 7 Pro computer. Fine for years! Then a series of power failures and system crashes.

Now Thunderbird looks very plain - black and white lines, no 3D blue colors, Delete button is text only, it used to be red. Entire interface looks simple and old.

Checked my outgoing and incoming server settings. They match the settings in Edison+ Email that I use on my phone. Phone is getting new messages, Thunderbird on my desktop is not.

Outgoing mail asks for a password each time, which it did not before. I know the password, but what a pain.

I have hundreds, actually thousands of emails saved in local folders. They are all there, but I am worried if I can migrate them if I move it to a different computer.

My inbox has nearly 300 messages now, and growing rapidly.

HELP!

Hi folks!

When I connect my Feedly RSS to Thunderbird's RSS subscription, I can't receive any new messages. In addition, I can't see the old messages in the folders. I couldn't find any way to solve this problem (for those who use Feedly).

When adding an RSS Feed, I don't get any valid URLs, I add it via Feedly "Organize Feeds ---> OPML Export ---> Download Export file" and then via Thunderbird "Feed subscripts ---> Import ---> My OPML file".

Thunderbird correctly reads all RSS feed URLs, file names, folder contents when I add this file. I save it and thinking it works and everything is fine. However, when I click "Get new Messages", no messages come through. I check the Feedly website a few minutes later to see if there are any new messages and I can see the new messages in Feedly.

In order to solve the problem and make it more understandable screenshots are below.

Thank you for your help, best!
