Around early December 2025, right after a new Thunderbird release (I forget the exact version number), there was a change in Thunderbird’s behavior when I click on “Write new message” on Thunderbird’s jump list for its pinned icon on my Windows Taskbar.

In the past, Thunderbird would simply open the composition window by itself and I could get right to typing the new email.

Now, however, after the early-December release, when I click on the same jumplist shortcut, Thunderbird opens BOTH the composition window AND the main Thunderbird program window along with it.

Is there a setting (maybe in about:config?) where I can revert Thunderbird to only opening the composition window?

I was able to locate the server, but it seems that the password is incorrect. I entered the password for the email service I am currently using, but it does not work. Could you please help me regain access?

I am trying to follow the guide linked to install Firefox on an older Chromebook. It looks like the device should be supported, as running the command cat /etc/os-release returns that it is version 10. When I get to step 4 and try and run that I get a permission denied error and later steps do not work.

I did try the Google play option on the Chromebook, it says the device is not supported.

Hi! I just did a clean Win 11 reinstallation on my laptop and must download all my accounts again, including Firefox. I can't remember my username. Evidently it isn't my e-mail address or my first and last name. Do you know if there's a way to either retrieve it or create a new username on the website? Thanks in advance!

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?

Very little to do with accounts, but none of the selectable topics cover 'user Interface'.

Used to be able to open different accounts in different windows. Can't remember how, but it was obvious. Once new window is created, each time Thunderbird is started it re-creates them. I accidentally closed one and can find no way to re-open it. I use three email accounts each needing a different mindset, so keeping them in different windows helps. Also one has a screendepth full of folders and so is easier to handle in its own window. (The others are still there but only take up one line each when collapsed.

Hi

Just checking when ThunderMail and Pro will be available? I'm in need of email services for my small business and just don't want to subscribe to Google. I love Thunderbird, glad it survived so many transformations over decades and would like my subscription contribute to further development.

Can you, please provide me with at least estimated timeline?

Thank you S

https://errors.edgesuite.net/18.acf7d517.1771548295.4f66cee0 is what I get when going to https:\goddady.com as of today. Running on Windows7 (no, I won't upgrade). Tried a variety of changes. But Chrome works fine. Any suggestions?

Hey everyone! :)

I hope all is well. I am trying out Thunderbird for the first time and i love it so far! However, i cannot figure out where the setting to stop restoring previous sessions/tabs is? I want it to launch in a clean startup with no existing tabs but i cannot find it anywhere! Can someone help me out?

Thanks in advance! -Adam

When I edit a Sent Email as "Edit As New Message", I usually change the subject line. I do this with the hope tthat his new message I am sending becomes a new thread. Unfortunately, it shows up as a thread under the original email, which I edited

How can this be fixed?

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.

For almost 15 years we have been printing emails (they are notification of orders). Probably 75,000 over that time period. Within the last 2 months or so, the second page has stopped printing. I have reinstalled printer drivers and software. Made sure I'm updating Thunderbird to the last release. I have looked at every setting. I tried using another computer and still no luck.

The printer does print the second page from other email apps like gmail and two page orders directly from PayPal etc.

I've spent hours upon hours and I'm out of ideas.

HELP.  :)

I’ve encountered a problem with Firefox that it fills up the RAM memory to the brim (12Gb) and especially when you’re on Facebook, it doesn’t empty the RAM memory but the data remains, you have to close Firefox and lose your web page, it just fills up, Why, should it be like this, very annoying!!!? :flushed_face: //A-B/Sweden

i can't do a search. I keep getting "problem loading page" and "secured connection failed" This is happening on both my windows 7 computer and my windows 10 computer. The same thing is happening if I try a google search as well.

I’m running Thunderbird 147.0.2 (64‑bit) on Windows. In this version, there is no Mail Toolbar and no Junk/Spam button available in the Unified Toolbar layout. My issue is this: When I manually mark messages as Junk, they stay in the folder where I marked them. They do not automatically move to the Junk folder, and there is no way to bulk‑delete or bulk‑move the messages I personally marked as Junk. I’m trying to find out: - Is there a built‑in way in Thunderbird 147 to bulk‑delete messages that I manually marked as Junk? - If not, is this a known limitation of the new interface? - Is there a recommended workflow for users who manually mark spam but do not have the classic Mail Toolbar? I’m not looking to switch to the Classic interface — I just want to know how to manage manually‑marked junk in bulk in the current Unified Toolbar layout. Thanks for any guidance.
