I tried unticking enable and it did NOT work. Help! I want the stupid filter gone. I have struggled for two years with the junk filter which does not work right. I have done shift J. The filter does NOT learn. A week aog, I saw that I could uncheck enable and that was supposed to stop the filter. That also did NOT work.

Today, an email I forwarded to myself from another platform went in junk. I never wanted any junk filter. It has been nothing but trouble and now I can't even disable it.

I have TB setup to allow customstylesheets with userChrome and userContent.css files generated. I have userChrome setup to my liking. Now I want to modify the userContent.css file so that I can set the background color of almost all elements is #222226 except for email text, hyperlinks, and imbedded images. I have this setup now in userContent.css:

body { background-color: #222226 !important; }

{ color: white !important; /* Changes font color to white for all content */ }

This changes most elements the way I want but it also flips the color of other HTML content, embedded images for signatures and other html content so its inverted to unreadable white content with white text. Is there a way to set it up so that HTML content and images are not inverted?

When I downloaded Thunderbird e-mail it gave me little delete icons on the right of the page when there is a e-mail. The problem is that those icon have a very very small pixal box to click to use. Can that be fixed by me somehow? I don't know much and had to go to google to find this Q&A section. Please help me with this Fix.

Is there a way to have TB auto delete Trash msgs older than a specified number of days. I don't want to just empty all the Trash folder, but I would like to be able to tell it to empty all messages over 30 days, or 42 days or whatever. Suzanne

Somewhere in my version of Thunderbird, there is an old adress of one of my correspondant which is recorded This adress is no longer valid and I have deleted it from my adress book Nonetheless, when I start to write my correspondant's name, this adress keeps being proposed among the first options for the automatic completion of the adress How can I delete this wrong adress from the hidden part where Thunderbird has stored it?

I'm just checking, is it near impossible to add an image to your signature? As old as thunderbird is why has this not been made easier or possible? Just curious, i cany be the only one. i have tried html in the box and attaching the html file.. I then read the image needs to be base64, tried that still nothing. After a few hours I'm sitting here thinking is this 1980? Please help, even if its to say not really possible. Sorry for being a bit snarky, I'm just confused why something so standard for years is so difficult.

Hello After Installing Thunderbird, and adjusted the settings to receive Outlook webmail, I have decided to stay with Outlook. Only problem is that I now receive two duplicate emails in Outlook. Please advise How I can correct this. Thank you

My problem is that JPEG attachments don't open, though PNGs do. I've got Original HTML actioned. Defaults are set to Fastone Image Viewer. Right click shows options but "open" doesn't work. Any ideas?

Since we needed to upgrade 2 PCs to Windows 11 (1x Pro & 1x Home) nothing works anymore with Thunderbird. It has MASSIVE and unsolvable problems to connect to our Gmail account via OAuth, Not only will it ask every single time again and over again to allow the connection, but moreover even after granting access it still can NOT send (SMTP) or save or even receive (IMAP) emails. It is maga frustrating and I am currently after days and days spend to unsuccessful fix the problem are at the point to looks for a more reliable alternative (if there is any). Just as background: Our Gmail account is about 14GB big, the local Thunderbird folder around 100GB; so yes it's big, but that's another problem, there are no easy or straightforward off-line archivers any longer to effectively and still easy accessible reduce the local archive.

Suddenly today my address books went from alphabetical to totally random listing. I haven't intentionally changed anything. No idea what triggered this change? Help, please.

Hi there. Have tried everything but still can just receive and cannkt send emails for my personal outlook account that I recently created. Other old outlook accounts are working fine (can receive and send). Basicaly have done everything that sugested here on forum. Please help. Thanks a lot!

I've (finally!) managed to set up a new account on my new PC (having found the required password, a long string of letters - where did that come from? - I would certainly never have chosen that and I was never informed of it). I also successfully managed to transfer my Profile from the old PC to the new one (thanks to your helpful article. However, While I have thousands of 'sent' messages I only have a few in my inbox and sub-folders (i.e. today's). (I originally used the recommended server settings (?IMAP) I was offered but then changed to SMTP/POP which is what I always used before without problems.) So - I go to 'Import from a Thunderbird profile' and it shows me the Profile Name and Directory details, but then says 'Nothing can be imported from the selected source' - but doesn't tell me why not, nor what I should do about it! Given the Profile has transferred successfully, why can't it be accessed? Any ideas appreciated. Thanks, David Collins.

I haven't updated Thunderbird since version 52.9.1 because of the interfaces which are painful for me and I don't see much. it still works well but does not support encrypted emails. I would like to install a recent version of TB but how can I make it look like the older, much more configurable versions? Please tell me if this is even possible.

Since the latest update to my Thunderbird installation (Windows 11), my previously created Mailing Lists have stopped working after always working well. Thunderbird Release: 140.7.0esr (64-bit)

I now get the message below when I try to send an email using a mailing list address:

• • • Committee <*** Committee members> is not a valid email address because it is not of the form user@host. You must correct it before sending the email. (Name partially starred out for security).

On January 1 my desktop version stopped downloading my GMAIL but my other non gmail are still downloading

I use Windows 10 and the version of Thunderbird is 147.0 64 bit

What can I do to fix this?

Am I doing something wrong?

I have one account in Thunderbird that pop's emails from a Yahoo account. If I delete a message in Thunderbird it goes to a local trash bin and on default stays there forever.

I want the emails to be deleted after 40 days in the trash bin. See picture. But it looks like it works exactly like it's described.

Messages are deleted from the trash when it's 40 days after they were originally send. If I delete a message in the inbox older than 40 days it goes to the trash and is immediately deleted from it.

I tried deleting several messages older than 40 days.

The counter of the trash increases for a split second with 1. If I look in the trash the deleted message is not there.

In my trash there are only messages "younger" than 40 days. At this moment the oldest is from December, 14 2025

Yes it works like the retention policy tells it should work. But this different from what I expect from trash folders
