I can't turn off 'threading' of messages. I hate that feature. I'll do my own damn 'threading'. Now the 'search' function is useless. Help me turn off 'threading' I run Thunderbird which I like, on my HP Windows 11 laptop.

"Threading" cannot be 'unchecked' in the dropdown menu.

I have been using Thunderbird Portable e-mail under Windows 10 for a number of years . About 4 months ago I installed on a Windows 11 computer - it worked for a few weeks, then one morning I received a message stating it will not run because a 16 bit program will not run in a 64 bit environment.

I am hoping that there will be a 64 bit portable version for Windows, based on my previous usage.

Would I be able to install the normal version on an external portable drive? When I go visiting, it is convenient to be able to take just the external drive. Currently, the external drive is a high capacity USB drive. However, if this is not possible, is the current Windows 11 version ready to go?

My current e-mail system is a long time DOS system via my ISP. That e-mail address is my only e-mail address, used for over twenty years. I would prefer not to have to change it.

What I have been doing is to use Thunderbird Portable to download my e-mails into Thunderbird on my computer, which allows me to store my e-mails offline for a financial year.

I am hoping to find an option to continue this by June 30.

I've used thunderbird for years. Now I can't get it back. I tried a clean uninstall/reinstall. Downloaded from the thunderbird site. Seems to install fine, but then says no profile recognized. I put some old profiles in the appdata\roaming\thunderbird\profiles in desperation, but still no luck. My clean uninstall did involve registry entries (Revo-Uninstall). So I'd like to get a clean start with Thunderbird, but it won't let me. Any suggestions greatly appreciated. I dread the idea of using another email after all these years!

For the past several days, TB has not been downloading messages from Yahoo. When I click to download, it will say "downloading message 1 of 36" and then time out.

I get this message when I double-click the progress bar: "Connection to server pop.mail.yahoo.com timed out."

The settings have not been altered in any way.

I've looked through the various discussions on similar questions in this community and on Reddit, but none of the suggestions have worked.

Help please.

(i tried putting in the name of the address book... that didn't work)

thanks

Hi - I can't seem to delete from my Yahoo Mail via Thunderbird.

With Yahoo's new mailbox limits I wanted to clean up my Yahoo mail box and Yahoo obviously does not provide any decent tools to support search and delete.

I downloaded Thunderbird and despite several deletion attempts my Yahoo mailbox still shows 160,000 emails whilst my Thunderbird client only 9,000 - so when I delete it is not syncing.

Most emails are deleted from Thunderbird however some are now reappearing (in Thunderbird). No deletions from Thunderbird are reachign my Yahoo mail inbox, however I can send emails from Thunderbird and see the sent and received email in Yahoo and I can add folders in Thunderbird and see those folders in Yahoo.

I tried several things

- immeadiate delete in Thunderbird - moving the emails to a folder in Thunderbird and then deleting from that and then deleting the the folder - I check this article https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo and everything appears correct

I've had to pay for extra storage to get the code to make this post.

So I have a list of folders some of which are the default folders some are custom created.

When I try to re-order these it is very hit or miss: I select a folder, drag it to where I want it to go, wait for the blue placement line to appear and it may or may not re-locate. Or I simply can't move the folder I want to move and so I move folders around it in order to achieve the layout I want.

It is as if success depends on whether Thunderbird is in the mood for a particular move to happen and I find it really frustrating. It should or shouldn't work, it shouldn't be that it works sometimes.

What is going on with this?

I have folders designated A-G, H-Q, etc. and in those folders are subfolders. The A-G folder displays as though it is in Italic font and I cannot move a folder into it.

Wise, a currency transfer business, claim to have sent me several emails as part of a two stage verification process. But they never arrive! They will not accept that the problem is at their end, they say it must be my email programme which is Thunderbird. I have searched everywhere but they aren't to be seen. They say to look in my spam folder but Thunderbird doesn't have one - Thunderbird flags up what it thinks is spam, (usually correctly), but still deliver to my Inbox. Has anybody any suggestions as to what I should do? Until I login, I cannot use my account.

Hi , I am using the MacBook Pro M5 which is running with macOS Tahoe 26.5 . I have installed Thunderbird mail with version 150.0.2 . After the initial installation with only one account with few mails in the inbox I found the App opening time is abnormally high & is more than 1 minutes . I have removed the mail App few times & re installed it ( even I have re download the app from net again) , but the problem remain same .

I have removed the old folder & files from - ~/Library/Thunderbird/ , ~/Library/Application Support/Thunderbird/ , ~/Library/Caches/Thunderbird/ , org.mozilla.thunderbird from ~/Library/Preferences/. before the re installation & re started the laptop , but no improvement in results .

Also in mail setting references → Unchecked the option - Enable Global Search and Indexer Disable all Extensions and Themes under Tools → Add‑ons & Themes (No Extensions is installed) .

Just to inform that the apple mail is working fine in this laptop .

After all the above trails the results are same , the app once quit & re start - it takes around 1.5 minutes to open after which the app works normally with out any problem . Please suggest if any solution is available for this problem . Best Regards Gautam Banerjee

I just got a new computer and when I download e-mail on to my computer, it stays on the web site and when I get e-mail later that day, the previous e-mails I downloaded are still there and they are now duplicated on my hard drive. I get hundreds of e-mails per day and besides being a hastle, I will reach my quota pretty quickly. Thank you. X@riseup.net

Since this didn't happen with my previous computer, I assume some setting got changed. I hope this is one of those easy-when-you-know-how things.

As the topic says, the message list turned from the usual dark-mode look, to a full black background after updating to 151.0.

Was this an intentional change? How can I revert it?

Been using outlook since 2000, I am tyrin to cut the umbilial cord to outlook as it is craper each year that passes.

Can i have more than 1 sig as i use maybe 10 different sigs for different reasons?

I see a use file do i get to choose a differt file when inserting sig or am i stuck with one and have to manualy change file or copy from somewhere else.

Once i get Thinder runnin i wil be happy to support on a monthly basis but i need to se if ti will suffice.

The attachment icon is missing from the message display pane in incoming emails in Thunderbird. Before it was always displayed at the bottom of the window. I have 'Display Attachments Inline' checked and I also repaired the Inbox folder but still no icon visible. I am using the latest version of Mozilla Thunderbird 151.0.

I asked for help a few weeks ago, but all the suggestions failed to help. I still get the "Unable to connect' message as soon as I open up the Thunderbird mail app. I have tried to delete and reinstall my outlook email accounts, but no luck. It seems the problem is with Thunderbird inability to make the connection to any of my email accounts? On other platforms they work fine??? I don't know if Thunderbird updates are the problem. I even tried to delete and re-install Thunderbird, but nothing changed. I am about to abandon Thunderbird completely, unless someone knows how to get me connected to my outlook email! Thanks

It's been almost a week now, and my 2 Microsoft email accounts will not connect to Thunderbird anymore. All was fine for years, but something changed that I can't figure out!?! I have gone to my Microsoft email server and checked that my passwords still work. I even updated one and it works on Microsoft server but not Thunderbird's!?!? I even deleted one email account from Thunder bird to re-install it, but when I tried a fresh re-install Thunderbird still won't connect to Microsoft server??? I'm at my wits end, and may abandon Thunderbird completely if someone there doesn't help me connect!!!

I have been using this system since 2008 through a company called Bluewave. They are shutting down at the end of May and I need full service for everything but main email. I need to talk (like on the phone) to someone who can help me in some way. I am not computer savvy so please have someone patient. I own AuPurr Cat care and don't want to lose our database, etc. info already on file. Am I contacting the right company for this help? My direct # is [edited phone# from community support forum]

Hello,

This would have been a reply to https://support.mozilla.org/en-US/questions/1390397?utm_source=chatgpt.com which is one of the top google results for "Thunderbird make font fixed length addon"

Some html text is hard to read, I would like a button, to make it all one more readable font. (font override toggle button to variable lenth font) and a button to make it a fixed length font (font override toggle button to fixed lenth font) Maybe a button to also strip formatting like bold/italic/coloring etc..

The solution

Preferences > General > Language & Appearance > Fonts & Colors > Default font > Advanced > Font Control > Use fixed width font for plain text

Which is too deep into the setting to casually flip for one message and then bring back to normal. I don't want this forever, just when there's one hard to read email.
