Hello! I recently got the update to Thunderbird 128 on my PopOS laptop via sudo apt update/upgrade. I don't know what the previous version was. Since the update, Thunderbird will spike my CPU to 120 - 140% (per command-line "top") if I have an interaction with it (e.g. reading and then deleting an email that was received) after the program has been sitting idle for several minutes. After a few minutes of loud fans, things calm down again so I presume Thunderbird is doing some sort of maintenance routine that completes successfully.

I do not have the global search index thing turned on. I did not change the default mailbox db idle time. I do have rather large mailboxes that are synced via SMTP, from three different providers. There are dozens of folders (not hundreds) containing thousands if messages (but not tens of thousands). Hopefully that gives an idea of scale .. I don't have a massive overload of untended email history but I do have a quantity of historical emails that the system has to deal with.

I followed the excellent directions online to obtain a profile during one of these high-cpu sessions. It is available at https://share.firefox.dev/4dAmyAz

Please let me know if there is anything further I can do to help diagnose this issue, such as generating more specific profiles. The high-cpu state is a pretty common occurrance now.

I was sorry to see that the 128 Nebula release did not fix the longstanding problem that Thunderbird is very slow to load in Sonoma, and has been since the Sonoma release. This is with 128.0.1esr (64-bit) on an Apple M1 Mac Mini with Sonoma 14.6. I have the same problem on a 2018 Mac Book Pro running Sonoma with an Intel chip. The problem is NOT manifest on a 2013 Mac Book Pro running the last release of Big Sur. In all 3 cases the same email accounts are loaded, so it is some interaction with the OS. (I previously reported this for Tbird 115 under Sonoma, with no resolution.)

Specifically, when I start Tbird 128 on the Sonoma M1 the window comes up in about 2 seconds but contents are blank. The contents don't fill until about 30 seconds. This makes it painful to quickly hop into email to do something, so I am resorting to Apple Mail when in a hurry. If I do the same on my 2013 Big Sur machine, it's 2 seconds for the window to come up and 8 seconds for the content to fill. Upgrading from 115 to 128 did not change this on any of the machines.

None of the enhancements of recent releases are of sufficient value to compensate for this, so I wish the team would focus on ensuring speed on all platforms. Is there any clue what is going on?

128.0.1esr (64-bit) Release notes This has just installed and after 20 YEARS - it has stopped working, I cannot send or receive mail. Using Mac Sonoma 14.5 Collecting mail via elyan2.merula.net My inbox is stuck with the update message, that i cannot delete, mark as read or anything else. Rebooted a number of times .

Help, any idea what I can do ?

So - the "development" staff have taken away the ability to look back at previous events, have taken away the ability to export calendars as ics files, and have locked our data into incomprehensible and undocumented sqlite files. And they very neatly and conveniently leave all the "support" to volunteers, who have suggestions as to what *might* help. Such garbage I've never seen before in my life.

Quick Filter is still extremely slow on the newest version of Thunderbird (128.1.1esr). I asked a question about this previously. It was reported as a bug (see links below) and it says in the report it was fixed, but the problem still seems to be there in the newest version. Any idea when this will be fixed, or if there is anything I can do about it?

There is a thread about it on reddit. https://www.reddit.com/r/Thunderbird/comments/1e6hryp/quick_filter_is_super_slow_in_128/

There was a bug reported, and it is listed as closed (solved). Here is the bug report thread: https://bugzilla.mozilla.org/show_bug.cgi?id=1908761

Thanks for you help.

Ever since I've been upgraded to Thunderbird 128, I've been experiencing constant hangs. I'm running the latest versions of Thunderbird and Windows 10. My antivirus software is Windows Security.

This issue seems to be most acute whenever Thunderbird checks for new messages. Thunderbird's CPU usage jumps to between 25 and 30%, and memory and disk usage also skyrocket. Thunderbird freezes completely, and everything other program that's running at the time is slowed to a crawl for several minutes minutes. Troubleshoot Mode doesn't help.

Any suggestions?

Thanks.

Hello!

Similar to Ludas question of 11/11/23: There was an update about 10 days ago, after which the Quick Filter started working terribly slowly: 1. Even before I have written the entire keyword (including email address), Thunderbird starts "thinking" and crashes (Not Responding). 2. After some time, about 1+ minute, results appear. 3. I went through Safe Mode on Windows and Troubleshoot Mode on Thunderbird - no change.

This account has ~52k letters, IMAP. For accounts with a small number of letters, there is no such delay.

Hi to all, after the latest update to 128.1.1esr (64-bit) the quick filter is very very slow and hangs the PC (WIN 11, 16 GB RAM and SSD) for 10-15 seconds. Thunderbird no longer responds and this happens all the time, also with different machines. The version before the update was just fine. Anyone with the same issue? Can you give me some hints/solutions? Thanks, Antonio

I have Thunderbird 128 installed and just tried to get my gmail account set up. Everytime I try to add it, the Oauth window comes up, I log into Google, and then get a "malformed url" error and the oauth fails.

Anyone else have this problem with 128? Is there a workaround?

Since I installed Thunderbird on my new computer, I have been unable to send email using Thunderbird with my Spectrum account. I can receive email using Thunderbird with no problem.

I called Spectrum tech support and they confirmed that I can both send and receive email from their webmail app, so the problem is not on their end. They also gave me the correct settings to use for Outgoing mail, which I entered within the Thunderbird Account Settings. I read the articles on the Thunderbird support site, but they did not fix my problem.

My Thunderbird version is 115.12.1.0. My OS is Windows 11.

The attached photos show the failure message I am getting and also the account settings. Please let me know if you have any questions or if you need anymore information.

I really like Thunderbird from my previous experience so I really hope that you all can help me overcome this issue. My wife can send email from her phone but we really want to be able to do it from the desktop as well. Please help!

Thanks, Bruce

I use Thunderbird as an email client, and a POP3 connection to Virginmedia to download emails. This has worked pretty well for years. In the last few weeks the email content has been very slow to load. Although the list of emails in the inbox in Thunderbird appears quickly, when I select an email to view its content there is a delay of perhaps 5s while it says 'Loading Message...'. There is a similar delay when deleting a message.

Once a message has been loaded, it can be re-visited without a delay, but if marked as unread there is again a delay next time it is read. This is also true if I work offline, so it can't be Virginmedia's server.

I have another account using an IMAP connection which doesn't suffer from any delay. Thanks if anyone can advise.

Sometimes my Thunderbird Inbox (or some other folder) is empty, and it's Properties Location is empty. I've found nothing to fix that except to close Thunderbird and reopen it; sometimes needing to wait a few or several minutes before reopening it. That's always (finally) worked, but I guess I'm concerned that one time it won't work. What could be causing that?

Hello, PG&E just updated their webpage and it doesn't allow me to sign in. It informs me that Fire Fox isn't a compatible browser, all other websites are fine. It suggests Chrome as the preferred browser. We pay our utilities through their site and we enjoy Fire Fox.Can anyone help resolve this issue? Thanks

Yesterday, after downloading my emails from the weekend and deleting all of the junk mail Thunderbird suggested I compact my Inbox. I went and emptied my trash folder and then compacted my inbox. After the compacting was complete I could not get any of my emails to load in the preview window or in a new window. I then went to properties and tried the "repair". After that I lost all of my emails back to 5-24-21. Is there anyway to recover my lost emails?

I migrated to a new computer with Windows 11 and to the latest TB nebula. I copied the profile folders to the new system and it imported 20 years of email correctly. BUT every connections seems to hang and eventually times out. It almost looks like TB blocked by a firewall. Even checking for updates eventually times out. HOWEVER everything works fine in troubleshooting mode.

I have no add-ons installed. I have no VPNs or additional firewalls. Disabling Windows firewall entirely doesn't change anything. I tried "Make the changes and restart" with no success. I added thunderbird.exe to the exceptions to the windows firewall and even added a rule. I tried uninstalling and reinstalling.

Is there any setting related to the connection that would be different in troubleshoot mode? Apparently nobody has ever experienced this problem, I feel like I'm going insane.

Dear Thunderbird team and community,

long term user here, thanks a lot for your awesome software, absolute essential live-saver.

A few days ago, I did the update to 128.1.0esr (64-Bit) from 115 on win11. Very smooth transition, no issues with my 4 accounts, calendars etc. Great experience.

However, since the update, QuickSearch Ctrl-Shift-K filter that did instanteaneous filters on my 25k mailfolders came to griniding halt.

What happend: - Type a search term with filters on 'subject', 'from' 'to'activate freezes the app for many wall-clock seconds (5-10). Switching to another app and switching back gives me a Windows (Thunderbird not Responsive) in the title bar of the main window during that time.

What I expected: - almost instantaneus filter without noticable lag

What I tried: - deactivate, then uninstall expression search addon incompatible with 128 - restart in Troubleshoot mode with all addons disabled - reboot OS (Win11) several times - searched forums and stackoverflow for similar issues using different search term approaches and combinations

Thank you very much for any pointers how i could resolve the issue. Thanks again for your awesome product!

Jakob

Thunderbird no longer sends emails from my standard account. Receiving continues to work without any problems. The provider is Vodafone with the .kabelmail.de address Screenshots show the settings. Otherwise these always worked. I've already set the TLS version to 1 in Thunderbird, without success.

The error message can be seen in German on the other screenshot and means in English:

"Failed to send message. Error sending message. The mail server responded: spam id=155817::1723829084-40E2144E-91888C35/29/1527808. Please check the message and try again."
