I've always experience occasional TB crashes. According to my log history there was 1 in July, 3 in Aug, 2 in Sep, 2 in Oct, and 6 in Nov. I never really paid attention since the reboot was quick. But now in December I am losing work and it is a major problem. I've had 30 crashes in Dec and 21 in the past week. I have only 3 add ons and they have not changed, and a Copernic connector. I disable the Copernic connector and it didn't help. I have the same 140.6 on my Surface Go with the same add ons, except for Copernic and it runs fine. On both PCs I use Malewarebytes and WinDef. I have put exclusions for them in their setups. Even with MBAM completely disabled I've still had crashes.

I cleared the Cache and no help. I've even had occasional crashes in Troubleshooting mode. Here are my last 5 crash IDs

bp-070bf941-4e8b-41a3-8b84-3e3440251224 bp-a936f7c2-9ee3-4c38-b304-dab830251224 bp-8be9cf9e-8f2f-49bb-95cf-47e780251224 bp-12f8fc2c-c505-40f0-8c67-44b730251224 bp-9013fb78-086c-4327-9de8-62db30251223

Interestingly I’m also experiencing crashes with Firefox, especially ChatGPT. I cleared the ChatGPT history and that helped but did not solve the problem. I cleared the Firefox cache and in troubleshoot mode still have issues.

Otherwise my win11 PC seems to be working fine. I’ve run chkdsk and all is ok. Also scannow is ok.

Is my next step a profile rebuild?

Hi, I have moved to a new computer and transferred my Thunderbird account to it without any problems. However, I wanted to do a backup of my profiles, etc, but the old Thunderbird backup link no longer works. Has it been discontinued, and if so, what replaces it?

I need predictability where I can find it. Thunderbird opens how I left it, so I never know what's going to appear when I start it the next day. Isn't there some setting so that it always opens showing all 3 panes, regardless of my laziness at exit? It would also help with my autohotkey script if it knew what to expect. I suspect the lack of answers in my search suggests there is no such setting. How about a command line argument?

I want to use TB as client for a twc.com account. I do not want a TB email account; I want to use it to access my existing twc.com account. I have downloaded TB but the only option I see is to open a TB email account, which is not my goal. How can I find the option to open the TB site and setup to use TB as client for a twc.com account?

email address no longer imports new mail. The mail is there if I go into Gmail directly, but not Tbird. I have three email addresses, the main one only has stopped importing mail. How do I fix this?

I currently have two email accounts in Thunderbird (both from Virgin), and want to add a further one (from Hotmail). The new account is up and working, but I've only been partially successful in adding it to Thunderbird. I followed the procedure given in the Support Article "Automatic Account Configuration" and this worked up to a point, but it failed at Step 4 (or possibly 5). Thunderbird seems to be able to recognise the new account and add it to the on-screen list, but It claims that it can't find any messages, although I know that there are at least 10 in its Inbox on Outlook. Furthermore, although my other two accouts have subfolders such as "Inbox, Drafts, Spam, Sent, etc." the only subfolder that appears in the new account is "Inbox", which remains stubbornly empty!

I'm attaching two screenshots. The first one shows my Firefox screen with the three accounts and their subfolders (collapsed for "richardandmaya@ntlworld.com") in the left hand column. The new one is the one named "ailuros2@hotmail.com". The second screenshot shows the new account seen via its native Outlook, which shows all the messages that I know are there but which Thunderbird can't see.

Strangly, I seem to be able to send messages from the new account to other accounts.

Any suggestions?

The New Line (Enter) key always double spaces, which is intended for paragraph text. But for tabular text, this makes unnecessary white space. What key combination generates only a SINGLE new line character rather than TWO of them?

Example: Donor: xxxxx Email: xxxxx Phone: xxxxx Billing Address: xxxxx Bank: xxxxx; Account ending in xxxx

This screen defaults to single spacing; why doesn't Thunderbird allow it?

Why does Thunderbird keep adding the "--" to messages. Moved from Outlook to Thunderbird and every new message includes "--" (circled in the included picture).

Why is it doing this?

A fair number of folders in my primary email address's inbox have been out of sorted order for at least several months.

Most of them are folders I access quite often; they now appear AFTER what used to be the last folder ("Zoom").

If this is a "feature," I suggest moving the highest activity folders to the FRONT of the inbox rather than to the BACK.

HOW DO I RE-SORT MY INBOX FOLDERS?

Thank you.

I'm running Thunderbird 102.15.1 (32-bit); still running this old version after reading how awful many people found the next update to be.

I POP my personal domain email to TB.

Beginning yesterday, out of the blue, I started getting the error which I'm attaching when trying to download my email. Absolutely nothing had changed. I made no changes either within TB nor to my computer at all. Computer reboots haven't helped.

What should my first course of action be to resolve this?

Many thanks.

What 2 rows / 3 rows?

Upon starting Thunderbird today, it appears the connection to my two Outlook exchange accounts (through an Owl extension) are no longer functional. I can receive messages but I cannot send them. I have attached images of the error it returns first (Error1) and then the screen that results upon refresh (Error2). I can reach and send mail from my accounts using Outlook365 web access, so it must be a Thunderbird configuration problem. Please help!

I'm trying to respond to get help with Tbird. But now there's a problem posting. Suddenly the Mozilla instructions are in Cyrillic and I can't post. I would include a screenshot but although I took a screenshot and I can see it sitting on my desktop, the "Add images...Browse" function does not show it so I can't attach it. Here's the thread (reproduced from Preview pane).

Others have mentioned this but I'm not sure if there is a fix/anything is being done. The threads are all from previous Thunderbird versions.

I use Thunderbird for work. I have to find specific emails and folders - get to them quick. I am no longer able to do this. It's really distressing.

This is something really basic, that should be the default or else really easy to change.

I'm on a Windows machine and using Thunderbird 140.3.0esr. I've been using Thunderbird since 2003 and never had any problems. Now I'm panicking!

When T-Bird sends a message with an in-content photo, is that photo compressed to save space and transmission time?

I converted from Eudora. Eudora would compress in-content photos to save space and transmission time.

If T-Bird performs a similar action, is that compressed file saved somewhere?
