Thunderbird v102.15.1 is very slow to open in Win 7. Yes, I know Win 7 is obsolete, but I must continue on with it for a while longer.

When I open Win7 each morning and then try to open TB there is a very long delay before I get the TB prompt to select a profile, the then a long delay for TB to actually open, and then a long delay before I can actually select an email account to read. (I have 20+ accounts). I routinely open Windows Task Manager to see what is going on, and close unneeded programs.

In the past with older versions of TB back to 60.9.1, I recall seeing Thunderbird Profile Manager in list and changed the Priority from Normal to High or sometimes Realtime and that seemed to help. But with recent TB versions, the Task Manager has added several other items besides the Thunderbird Profile Manager - very long items that include something like "child ID1, child ID2 and child ID3." I have tried changing the Priorities of each of these to High or Realtime but am not sure that helps.

Eventually TB starts but when I go to my main email account and try to read Inbox with up to 120 emails each day, messages are very slow to load and I often get "Not Responding" for a long delay.

What is the solution to this problem? I move older messages from Inbox to local folders, delete Junk and Trash each day, etc.

Emails in two of my inboxes (maybe all four) are randomly disappearing. None of my email templates are showing up in either of my two template folders. This started two days ago and I cannot figure it out. Emails get downloaded, then some are just vanish but are still on the servers. Repairing the folders does nothing, but folder properties on my template folders show the number of messages that should be there. Thanks in advance for any help you can provide.

Recently a pop-up asks me to enter a password to receive/send messages in my Thunderbird emails. Each time I enter the password, the pop-up message comes back w/in seconds asking me to retry or enter new password or cancel. It seems there is difficulty logging in as imap-mail.outlook.com has failed to connect. Does anyone have any suggestions on how I can correct this issue? In simple terms please with step-by-step directions. Thank you kindly!!!

To start, I do receive most of my emails intact. However, there are the occasional email only partially appears. I see enough of it to know who it is from. As an example, I get a bill from xfinity and only what appears to be the graphic part shows up, but, the details of the body of the email do not appear. So I don't know what they want to tell me. All this is in regular Thunderbird. That being said, when I open Thunderbird in troubleshooting mode the full email is then visible. I have tried the reset everything and nothing seems to work. I have taken to only opening Thunderbird in troubleshooting mode as then I am assured of seeing the full emails, text and graphics. Maybe you can help me adjust something to fix this problem. Oh, I am using windows 10 on a pc. Thanks, Dic Bason

Yesterday Thunderbird worked. Today every time I download a message I have time for a coffee and watch the blue circle of death. The message does come up after a while but the program is so slow and unstable that it's not really usable. This issue seems to come and go over the last few weeks?

At least on Linux, all versions of Thunderbird with Supernova UI are unusable for emails which requires a hardware key to login. The "insert key / input PIN" never shows up in those versions. The bug presents on flatpak distributions and latest daily version (130) as well. The latest stable version that's working with hardware keys is 102, but it has some serious performance issues with large amount of calendar entries.

When I click the button to “repair a folder”, some e-mails have disappeared.

The inbox file is too heavy and cannot be opened as a text file.

I moved the defaults file to an external HDD and saved it over the defaults file on my computer. I could not restore them.

Is there any other way to recover my email?

I installed "cardbook" (from gitlab) and wanted to print the address list, entry for entry. How do I do that? This is not a generic TBD question. but perhaps somebody knows ...

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?
