I’m having some issues with Thunderbird. It’s running really slowly and making my whole computer lag. Thunderbird consumes constantly 8-9% CPU while it’s on. I’m using Windows 11 and Thunderbird version 128.4.3.esr (64-bit) on a laptop with fast NVMe drives.

I’ve added 8 email accounts, and the mail folder (Roaming/Thunderbird) is about 165 GB right now. I think it’ll go over 200 GB once all the messages finish downloading.

The problem seems to be with message indexing. The Activity Manager shows it’s indexing over 300k messages. Even if I leave Thunderbird running all night, it doesn’t finish. When I get new emails in the morning, the indexing starts all over again. It takes hours and uses a lot of CPU while it’s happening.

If I disable the "Enable Global Search and Indexer" option, Thunderbird works fast and smooth, and CPU usage drops a lot. But, I assume, this means I lose the ability to search emails.

When the lagging happens, opening an email preview can take up to 3 seconds (!), and deleting a message also takes 2-3 seconds. However, when I disable the "Enable Global Search and Indexer" option, Thunderbird works ultra-fast. Opening and deleting messages is instant, and there’s no delay.

Any idea how to fix this?

I've been using Thunderbird on my PC (Win 10) for many years, and the email does not download today. I tried reconfiguring the server settings but it says: The stat command did not succeed. Servier unavailable 21

Could anyone please help Thank you Mario

Please excuse my wording as I don't know all the correct terminology. I have several email addresses with our current local phone company with our landline/internet package. Since the internet service is so poor, I would like to discontinue this internet service and go with something like Comcast. Once we cancel our internet service with our local phone company, we can no longer use those emails addresses (name@embarqmail.com).

I'm trying to find the best provider that supports POP3 protocol as that works best for our household. And I'll need to set those email addresses up BEFORE I cancel with our local company. Can I set up emails with Thunderbird (name@thunderbird.com) or should I go with something like Gmail or Outlook or Yahoo? Trying to find the best solution so we don't have to do this again if we change internet providers.

I already do have one Gmail account and it says it supports POP3 protocol - but it doesn't always work - sometimes I get an email on my phone that doesn't come through on my desktop computer - and you have to type Recent: while setting up the account.

Any help would be greatly appreciated! Thank you!

Version thunderbird 128.5.0esr 32 bits

Many moons ago I used Microsoft's Outlook as my email program. When I would open Outlook, it would retrieve all of my emails from my ISP's server, permanently removing the emails from the server while downloading them into Outlook.

When I installed Thunderbird recently, it was to do the same thing. My ISP had sent me several notices that my email account was close to full, so I was looking for an email program that worked the same way Outlook does, and removes my emails from my ISP's email server as it downloads them to my PC.

The first issue I'm having is that Thunderbird does not appear to do this? Or do I simply have my Thunderbird account/settings set up incorrectly?

My next issue is directly tied to the first one. Every time I open Thunderbird it starts re-downloading all of the emails that it has previously already copied into my Thunderbird Inbox, but that are still in my email account on my ISP's email server. This is probably 15 years worth of emails and equates to thousands of emails I'm saving, and every time I open Thunderbird it starts re-downloading them again. I simply want to be able to save them to my local email client (Thunderbird) and store them on my PC's hard drive.

The final issue is also tied to the first two: As soon as it starts downloading the emails again, Thunderbird (and only Thunderbird) lags heavily and almost continuously. It lags so badly that it becomes incredibly difficult to write a new email in Thunderbird, and so I end up closing the program and logging into my ISP's email server and using their client to write my emails, or conducting my email business via my phone, which takes longer and is more challenging due to continuous fat-fingering of the phones tiny little keyboard.

So, am I missing something, or do I have some settings in Thunderbird set up incorrectly? Or does Thunderbird simply not work the same way Outlook does (or at least use to)?

Thanks in advance for any help or advice anyone is willing to give.

I had added on the Grammarly extension and I have changed my mind and want to remove it from my extensions. I want to take it off, but I'm not able to figure out how to do that. Please let me know how this is done. My email is: rpatterson22@cox.net Rodney Patterson

Hello. The latest update of FireFox 129.0.2 still has intermittent crashes. Sometimes I can't access my Google searches or links in emails don't work, then it works, then it starts to malfunction again. I have to restart my PC. Could you release a patch that works as well as before FireFox 129.0? On the other hand, Canal+ works perfectly Thanks. Kind regards.

How does one transfer addressbook entries from an old computer to a new one?

David from TB support wondered how I could get correspondence between help seekers and TB supporters when I followed the instructions I was given. I followed the instructions from November 9 and provided them in my email today. I suppose the problem is that I did/do not know how to place the entries from the old address book into a file that can be transferred from one computer to another. I assumed the file was abook.sqlite, automatically including all of my entries from the address book in the old computer. Apparently, this is not the case.

I need to know how to download into a file my entries from the address book in the old computer. Once that is done, I should be able to transfer that file to my new computer. I also need to know how to install the old entries into the new address book.

Thank you for your attention in this matter.

Przy próbie połączenia się z pocztą otrzymuję wiadomość że przekroczono limit czasu połączenia z serwerem, nie mogę wysłać ani odebrać poczty bo nie mam połączenia z serwerem. Co zrobić?

When I try to open firefox on my android phone, it just closes and gives me an error message which I have attached a screen shot of.

I do not know if this is related but this happened after I scanned a qr code and tried to open it.

I have un-installed and reinstalled the app and turned my phone off then on again after reinstalling but this did not help.

Pls can you help?

Hi! I would like to turn off the Reviewer Checker drawer that appears when I visit Amazon because it keep crashing my browser. Unfortuntely, using the settings at the bottom of the Review Checker also crash my browser so I can't untoggle the "automatically show review checker" setting. I searched for review checker in the main browser settings but it didn't pop up.

Amazon is completely unusable and I'm too lazy to log into Amazon on Microsoft Edge instead. Please help!

Good day,

I can't remember my password. Thunderbird found my credential but I don't remember the password of my account?

What can I do,

Regards

In Windows 11, the Address Book is accessed via an icon on top left of the TB main page or Alt+2. In Windows 11 is there a similar key combination to view the folders below Local Folders?

Is it possible to initiate the same process that discovers the server setting when you add an email account in an already existing email account to avoid making changes in the account manually??

Page seems to freeze, and mail/google-acces denied out of nowhere. Same message when trying to log in to MyHeritage. Message someone changed phonenumber recently. I didn´t. I am accessing internet via cable to Iphone. No wifi or bluetooth. I suspect someone is trying to get illegitimate access.

Thunderbird 115.4.1 (64-bit) on macOS 14.6.1 Server Type : POP Mail Server

In the MAC hard-disk, size of the many of the folders stored in local directory, are much larger that the size on TB.

For reference, On TB, "_cc folder" is 3.8 GB On Mac Finder, "_cc folder" is 13.63 GB

I have right-click the folder and press "compact". The folder on TB reduces in size. But, the folder on the Mac harddrive does not reduce in size.

Now, I am unable to update my Mac OS, because these emails files have occupied most space.

Request your advice.

Thanks
