I have been using Thunderbird for 20+ years, maybe as many as 30. Forever. I have moved my profile across several versions of Windows and multiple computers. There are files in the root of the profile with a modified date of 2009. There may be older ones in sub-directories. There are 18 folders and 125 files. I suspect a lot of this is clutter left over from earlier versions of Thunderbird. In the Mail folder alone there are several hundred files and folders excluding the WDSEML files and actual emails.

I'm toying with the idea of starting fresh with a clean install of Thunderbird and getting on the correct release channel but I don't want to bring along what appear to be hundreds or thousands of unused files and folders.

I there anyone that can identify what profile files and folders to keep and what can be deleted?

Thanks for your consideration.

Hello,

I don't know if it's because I don't have the latest version of Firefox. But I cannot find tab grouping. I have checked to see if there is an update, but I can't find any update at all so just wondering what's going on. the version of Firefox I'm using is: 153.0 (Build #2016172927)

Thanks for the help

I recently changed hosting and now I am getting login boxes nonstop to my old servers. I see no way to remove them and this is so annoying I may have to change from thunderbird. All my emails are there, it just keeps checking for old servers.

Thanks in advance!

Hello! I'm on Debian, and there Firefox ESR is the default browser, it is now basically unusable as it is so out of date that Cloudflare Turnstile no longer works.

This is a major problem.

I have opened a ticket over at Cloudflare, but they have not commented at all on the problems: https://community.cloudflare.com/t/turnstile-not-woring-for-the-last-few-days/939637

Thank you for your time.

I'm running TB on Windows 11 on a Dell Desktop machine. It's a pretty basic installation with EE Cyber security, which is I think Norton. I've been using TB for a couple of years but recently it has almost stopped working. I notice from Task Manager that TB is massively leaking memory and consuming much CPU time. I don't think I have any add-ons and I only use TB for email. It's now so bad that I'm even unable to go into TB's Settings or Tools or anything else. I've tried creating an exclusion for TB profiles and TB.exe in the Norton. I've tried starting TB in troubleshoot mode but all to no avail. I have it in IMAP, Port 993, SSL/TLS for incoming mail and Port 465, SSL/TLS, Authentication Required for Outgoing mail. I'm currently often unable to even access mail previously downloaded to the local Mail folders, TB is just hanging with the bar in the lower right corner endlessly running along. Most puzzling of all, is that very occasionally is starts working again and then I dare not switch the machine off! It's become an indeterminate system. Please help, I'm nearly eighty and trying to organize my holiday, which is needs email to make bookings. Thanks in anticipation.

Hi everyone,

I'm trying to access some old emails which I know were stored on a laptop running Ubuntu 20.04. The laptop was wiped years ago but I have restored the data from a backup in October 2023 or thereabouts.

When I try to open Thunderbird it throws up a dialogue saying 'You have launched an older version of Thunderbird' suggesting I need to re-create my accounts. I just need to access the emails from the restored data and I'm worried if I connect to the mail server that my settings might just erase the emails all over again.

What should I do?

Thanks in advance. Any help would be gratefully received.

Thunderbird: 153.0 (64-bit), Windows 11

Have noticed that my TRASH Folder is missing in the folder view. The actual folder exists, it just will not display.

Also creating new folder under are created (I checked the mail folder) but will also fail to display. Creating subfolders into an existing folder works. And moving it under INBOX, making it a subfolder also works and displays

Any ideas how to recover/display the TRASH folder and new folders ? As the TRASH folder is missing it means I have no way to look at deleted email or recover them. Nor any way to search delete emails.

Emptying the TRASH works - no errors.

I haven't used Thunderbird on an office computer in several months. When I opened it, the most recent emails were from October of last year. Nothing seems to be updating or refreshing. How can I reactivate the account?
