Thunderbird Community Forum

I need a filter on a message to FULLY FINISH before a next message starts to be filtered. The "help" (quotes because it's an abyssal crap) says that simply ending the filter with Stop Filter Execution does it - but that's simply NOT TRUE: calling a console program in the filter, I can see five DOS boxes opening at the same time with five messages matching, i.e. the filters on the next message DID NOT wait! So... what can I do??

All of the above is because I'm getting "Too many simultaneous connections on the server". I'd like to limit the concurrency, but it only seems to be possible in IMAP, while this connection is a POP. Why only IMAP??!

I have Thunderbird on the old computer. For twenty+ years I have read the instructions for moving it to the new computer. i cannot understand/am not at all confident in my ability AND I have only ONE keyboard/mouse. I have to move it from one computer to the other to operate them.

Right now all email is on the old computer, no email is on the new computer. No email has ever been on my cellular telephone. One set of periforals - keyboard/mouse.

I DO have the Bravura, the Plugable transfer cable and accompanying software, and many other things came across, but not the Thunderbird.

I want to do the move/installation correctly so that not one stored email is lost or corrupted.

I need help.

Hello - new forum user with some previous familiarity with Thunderbird. I'm looking for advice on mail import from Outlook (M365) on Mac OS. I will only be using TBird for accessing historical mails in future rather than as the main mail app going forward.

I have installed Thunderbird and looked at the Import Tool but it doesn't list Outlook as an option. I've looked through the Import Tool support pages and I can see Outlook is an import option but it only seems to appear when I filter the web page based on Windows 11 rather than Mac OS.

Am I able to use the Import Tool on Mac OS with Outlook?

I'm using Mac OS Monterey 12.7.6 and have Thunderbird 153.0.1 and Outlook for Mac 16.89 (M365) installed.

If the Import Tool isn't available, is the next best option to drag individual folders from Outlook to the Mac desktop to create MBOX folders and then drag those into Thunderbird?

Thank you in advance.

Neither my wife nor I can access email on our respective PCs. This has been the case for four weeks. We can access email by our Android phones, but we really want to use our PCs. I've tried to resolve the problem and failed. Previous to this failure, I had an account with BT but this was transferred to EE. When I attempt to log in to my mail account, I receive the message "Could not connect ... :the connection was refused". I can also add is that in my Account settings, Outgoing Mail server I see a message "Connection to server mail.btinternet.com:465 failed."

T-Bird is Freezing (Hang?) from start to freeze was 5 minutes and a few seconds. Have turned off hardware acceleration and now it freezes at just under 5 minutes. Have put on updates. Currently 153.0.1esr (64-bit). I have captured profile, and re-installed and picked up the profile. Still freezes. Turned off AV. Still freezes. I have compressed and "repaired" all folders. Still Freezes. I forced folders to get rid of anything older than 30 days. Still freezes.

I have been running the task manager, and T-Bird in frozen state is only using 4.3% of CPU at most. I do not see any slowdowns for any other program. So this is not a CPU constrained problem. And it certainly is not memory constrained.

All this started within the past month and I think it was after I put on an ESR update (don't remember which one).

I can kill T-Bird and start it and it will get mail if any, and will function for about 5 minutes and then freezes (or hangs). The system is set to fetch mail on start up and then every 27 minutes. I am not using Account hub (and don't know what it does).

One oddity -- This is a W11 Home system, and Mozilla keeps saying it is a W10 system. Could this be the problem? Wife is running a lesser laptop. It is also running T-Bird, but her O/S is a W11 Pro and she is not having this problem.

After updating to 153.0.1esr(aarch64). the SEND button has disappeared. There's no way to send an email. (I can receive emails.) I am a Mac mini M2 Pro. OS 26.4.1

I cannot find a link to download a previous release of Thuderbird, which was working fine until this update.

when I try and add my microsoft outlook account, it redirects to a webpage, which after saying yes a few times with an already signed in session, redirects to localhost 44645. localhost 44645 notably does not seemingly direct to anything, and thunderbird does not change. clicking "continue" re opens the microsoft webpage How should i connect my outlook account? system details; ``` OS: Linux Mint 22.3 x86_64 Host: ThinkPad L14 Gen 2a Kernel: 6.14.0-37-generic Uptime: 7 hours, 40 mins Packages: 2177 (dpkg) Shell: bash 5.2.21 Resolution: 1920x1080 DE: Cinnamon 6.6.4 WM: Mutter (Muffin) WM Theme: Mint-Y-Dark-Aqua (Mint-Y) Theme: Mint-Y-Aqua [GTK2/3] Icons: Mint-Y-Sand [GTK2/3] Terminal: gnome-terminal CPU: AMD Ryzen 7 PRO 5850U with Radeon Graphics (16) @ 4.508GHz GPU: AMD ATI Radeon Vega Series / Radeon Vega Mobile Series Memory: 14803MiB ```

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

+ a screenshot

Anyone can help ?

Best Olivier

I purchased an Iphone 17 Pro Max and am trying to get the same email as I do through Thunderbird on my I Phone. How do I set this up so that I can see the same email on both the pc an Iphone

It was working fine on the new computer until yesterday. Now I get a pop-up box that says: ' Unable to connect The connection was refused when attempting to contact localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure Thunderbird is permitted to access the web.

Only a recent problem. I can receive emails just fine; only the sending of emails is affected. On the same computer, I open the Gmail website in my browser, and I am able to send emails just fine.

I checked my security program, Bitdefender, and there are no notifications relating to this issue.

Any help on what to check next?

Why am I getting this message when I try and send an email from my Mozilla email client: Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again.

My Windows 11 was recently reinstalled to factory settings, which uninstalled Thunderbird but saved my mobx files. I used Thunderbird exclusively to view older emails that are stored on my PC as mobx files. I do not use Thunderbird as an active email client. I reinstalled Thunderbird, but have been unable to get it to find my mobx files that are stored together in a folder.
