I have a completely vanilla install of TB fully up to date as of this writing [it is version = 156.0.1 (aarch64) and I checked for updates], no extensions, no proxy, on a new OSX 27.0 (Golden Gate) computer and even when idling it is using substantial resources. The only thing even remotely non-basic is their is the Proton Mail Bridge to connect to Proton Mail for one of the linked email accounts, but that is its own little program with its own threads and takes almost no system resources even when sending or receiving mail (which is not happening currently.) Look at the attached screen shot.

In the screen shot I have left Thunderbird to idle for about an hour. No new mail in that time and other then clicking on or off the window to bring it to the fore I have not interacted with the program at all myself. Meanwhile Thunderbird and its Thunderbird GPU Helper are using substantial amounts of the CPU and GPU, have a combine total of 86 threads (more then any two other things running except the kernal tasks) and are hogging ram (not depicted).

Meanwhile among a few other applications (Apple Music, OfficeLibre, etc...) I also have Brave Browser opened in the background running with two windows and a total of 8 tabs wherein Brave is actively downloading GB of data from MEGA as well as performing other admittedly lighter tasks. Even when doing all this, Brave barely registers on computer resources compared to Thunderbird and Thunderbird GPU Helper when they are just idling.

Is this all proton mail's fault with the Proton Mail Bridge? If not is there anything I can do to quell the hunger for computer resources of this voracious beast of an email client that is TB and uses resources as if it were a video game even when idling?

HELP‼

Are there any •SERIOUS• “Thunderbird” savvy computer geeks in 155.0that could help me merge “old” user profile directories from *crashed* computer to a new computer without messing up either one?🙏

i used to do this stuff (with my eyes closed) but I no longer remember if I had breakfast today and they are my wife’s files! 🤬

I have new notebook computer plus the •entire• old computer data on a USB stick.

Windooze 11. TBird 152.0 installed on June 20th. Now it seems like TBird is not displaying HTML emails properly. They are displayed but not at the beginning. The first line is sometimes just the bottom half of a sentence in the email (if that makes sense). I can't scroll back to the beginning. If I go to outlook and display the same email it displays fine.

Did something change in 152.0 to cause this?

Thanks, Ed Mazurek

Bonjour, La langue FRENCH est cochée dans mes paramètres et pourtant à chaque ouverture de la boite mail, tout est en anglais ! Je veux uniquement la langue FRENCH.

Merci

After many succesful years using Thunderbird suddenly the update 5.18.0 (64-bit and reporting as supposedly up to date) ) has completely lost all my folders and screwed up my email accounts!! I've been having an absolutely ghastly time for weeks trying to make sense of it and just feel like junking it...HELP! My email accounts that have been working successfully without problem for many years now sometimes send and not receive or the other way round, not send but receive. Additionally I cannot access critical and important emails (serious medical, legal and personal). I tried to change the staus of the accounts from POP to IMAP and ...lo and behold, the program does not allow it!?!? Why the hell not?

If I type a date for example 24th October, Thunderbird changes what I type to T4th, if I type 22nd, it changes to N2nd, the 5th becomes Tth and so on, I have tried all sorts but I cannot find a fix apart from typing the 22 then leave a space, type th then go back and delete the space, then I have what I want. Also if I press ctrl+B to type in Bold, and let's say I type R9.88, the program changes that to a capital B, and dumps my cursor in the next line, again I have tried all sorts and can't get that fixed.

Lastly, I have done my signature using Account Settings, Signature Text, I have ticked the "Use HTML" and typed my text in three lines, my signature shows as a single line with only a space between.

So, Kind regards Mark Collings Telephone Number Shows as Kind regards Mark Collings Telephone Number.

Can you give guidance and solutions please

Yes, this outlook account was made earlier this year. I've tried all of the "fixes" offered on here and across the internet. I'm changed to to password and got the app password. I've deleted 2FA to see if that would work. I've deleted the Oauth key and it refreshed to a new one. I've done it all and TB-sync is not available to me cus apparently now i'm right outside the app version limit.... how convenient. It's very frustrating as i really like the app and still use it to read my emails but it's very annoying to have to open the outlook app and go through all that just to send an email. I keep getting told it is possible, i've been battling this on and off for months. I cant just get a new email either as i already swapped everything to the outlook one and my work using out look as well. i am able to sync my calendar even but apparently just not my outgoing emails. I would like to transfer my email but the other email i have is a proton email and they are a whole other headache. Please help.

One day after windows update, my thunderbird can't not download email from yahoo, microsoft, google..etc I tested the connection be fine but I can't recive any email

I installed Thunderbird. Added 3 email accounts successfully. 4th one glitched and sent me down a rabbit hole.

The 4th email address appears on my list but I get an error message.

Login to server imap.mail.yahoo.com with username ______@yahoo.com failed.

I'm trying to remove a couple accounts that I no longer use in Thunderbird. A window keeps popping up asking for a password, but the mail service is no longer available. When I click on the red delete button for that account, nothing happens. I've deleted all the mail in one of them which I was able to do as I thought I might need to do that first, but I still can't delete it after that. The other one won't even let me delete the emails. How do I delete these so I stop getting asked to put in a password for accounts that are no longer valid and I don't want anymore?

In TB prior to v.155, folder message counts were not shown at all if the respective folders were empty. That is, instead of showing "0", TB did not show anything.

Now, after updating to TB v.155.0.1, I see dashes (horizontal lines) in the folder tree to the right of each empty folder.

Is it possible to revert back to the original behaviour and get rid of those unsightly dashes? They only add visual clutter (my opinion, obviously) while not providing any extra information.

Thanks.

I am trying to migrate from Microsoft Outlook 2021 to Mozilla Thunderbird. I have successfully imported the email from a number of different email accounts. I would now like to import the archived emails held in a number of PST files. The import tool would seem to be what is required, but it does not seem to allow me to select the PST files that I wish to import. I am concerned that it will try to import all email messages from my Outlook 2021. Is there a way of restricting it to just individual PST files?

A few times I have missed messages that have have been inadvertently placed in the Accounts Spam Folder. Is it possible to to indicate that the Spam Folder has contents in the same way contents are indicated in other Account Folders?

Hi,

I'm running the latest version of Thunderbird 140.12.1esr on 15.7.7 (24G720) on an M1 processor.

I'm witnessing Memory leak > Thunderbird who usually use 800MB jumps to Gb up to 60Gb

It makes this version unusable.

Here is a loom of the incident: https://www.loom.com/share/0b8e661b42d64d749d80adfd71fd1e04

Anyone can help ?
