Now the Message Header Customizer I was sent to about a week ago is no longer compatible with Thunderbird 149.0.

Is there another somewhere I can install?

I use a number of add-ons to help me out. Unfortunately, the following add-ons aren't working right now: Quicktext, Send Later, TbSync (where and how do I integrate it into Thunderbird?). When sending an email, I have to go through “File” > “Send”—there’s no button for it. The VBA call to send a generated email truncates the string, so the attachment isn’t included.

I’m sure some add-ons will be updated. But this is hitting me hard right now.

I've just transferred my profile to a new computer, for which I downloaded TB152 (had been running TB128), and no add-ons/extensions work. Of course many were rendered inoperative with the update, but that's not the issue, because:

1. Even those which claim to be compatible, or were updated since the transfer for the purpose of extension compatibility, do not work.
2. Moreover, when I invoke the Add-ons Manager to inquire about the various non-working extensions, none of the links (which can be seen and read by the OS), can be invoked or even copied (to be, for example, pasted into a browser window).

I went through the standard [[Mozilla Support diagnostics|https://support.mozilla.org/en-US/kb/hyperlinks-in-messages-not-working]] and found no answers. Can someone suggest a next step?

Trying to understand why this problem is related only to the extensions, I examined the profile's "extensions" folder. There are 40 .xpi files (same as the number of mostly-disabled (and mostly-expired) extensions in the Add-ons Manager), along with a subdirectory named "staged" containing 7 empty folders with what appear to be .xpi filenames - though none of those empty-folder-filenames match any of the .xpi files in the parent "extensions" folder. Because the "staged" folder has a recent timestamp (apparently the last time TB shut down), it seems to have some significance to TB operation - but what can be the use of it is more than I can see. What is the significance of that folder and its contents?

Two final (and possibly related) questions about this "extensions" folder:

1. Is there any way to relate the <filename>.xpi to the name in the Add-ons Manager?
2. Since nothing in the "extensions" folder identifies which are enabled, there must be some file containing a functional description of the folder's contents. Where would that be?

Grateful for any pointers, -John

I'm using Thunderbird vesion 149.0 (64-bit) on Windows 11. Our Email host has a 100 emails per hour limit. We need to send out 400+ emails to subscribers and are having issues with using only Send Later and BCC being rejected by certain email domains and or going to spam. Is there a way to use both Mail Merge and Send Later to send 100 emails to the recipients {{Email}} {{Name}}, pause one hour send another 100?

I used to use Foxmail as my email client. When writing emails with oversized images, I could right-click the image and select the "Auto resize it to proper size" option to make the image easier to read. However, I can't find the same function in Thunderbird. Do I need to use an extension, or is there another way? Can someone please help me? It's really frustrating.

Somewhat frustrating ... just after installing and setting up CardBook for Thunderbird on all devices... it automatically deactivated and "disappeared". CardBook no longer is compatible with Thunderbird.

Hope there will be an update soon that allows to keep all the settings...

Thanks.

As of a few weeks ago, none of the links on the Add-ons Manager Details pages in my TB 152 work, e.g. Author or Homepage. Moving the mouse over them, left-clicking on them, right-clicking on them, no effect at all. Which is annoying, as with several add-ons I use I'll want to go the add-on's Github page to look for new betas, report issues etc. Those links all used to work, opening the linked page as a tab in Thunderbird, but now they don't work at all, not even a right-click menu option to open in browser. Still not working in 152.0.1. This isn't only with me, surely?

A while back I complained about this exact thing here: https://support.mozilla.org/en-US/questions/1401708 — thread's archived now so I couldn't reply there.

Ended up building a small add-on myself since nothing else out there worked anymore. It makes every global search open directly as a list, no more clicking "Show results as list" every time.

Free, open source, no data collection. Can't be listed on addons.thunderbird.net right now (Mozilla's paused reviewing new add-ons that use Experiment APIs), so it's a manual install for now. Apparently this is getting built into Thunderbird natively from version 154 (bug 580252), so this is really just a bridge until then.

Posting here in case anyone else still lands on the old thread like I did.

I've developed a thunderbird add on. Now I need an extension ID I've read https://extensionworkshop.com/documentation/develop/extensions-and-the-add-on-id/

So how do I get an extension ID?

ThunderBird upgraded to v153.0. Since then EAS and TBSync have stopped working. Extension Manager have disabled them and report both are incompatible with TB v153.0.

The option to "Find an alternative add-on" for both fails to find an alternative version to work with TB v153.0

Are newer version of EAS and TBSynce imminent?

Hi,

we developed an add-in for MS Outlook. The add-in, connects to a mail message, and reads information from the mail - to transfer information to a special journal system.

Is it possible via API to Thunderbird, to create Add-Ins as seen from MS Outlook?

Best regards, Michael Vad

Been using Tbird for quite a while. Currently using ver. 149.0.2 but problem started before updating. Used to have a tab called Cardbook which shows all my contacts and is synchronized with Google. Its gone and I don't see how to add it back in. Advise please and thanks.

This is a continuation of the thread - [is being managed by your organisation CAUSE: Bitdefender]

The solution of deleting the Registry Key does not work. It simply comes back after reboot. I have engaged with BitDefender support and they suggested the same thing - they also added to uninstall TB which I am not going to do.

The issue is that the BitDefender extension is not installed in a normal way, and cannot be removed. The settings in BitDefender do not make any difference, I cannot change settings in a Thunderbird account eg change a folder location, it looks like it works, but it actually does not.

I did find in the about:config extensions.webextensions.uuids key has the bdThunderbird@bitdefender.com entry but there is no indication as to what other strings belong to the entry and I do not to mess things up.

I do realize this is a BitDefender issue, and i did follow up with their support but I am wondering if anyone has solved this annoying issue.

Thanks

I'm thinking about using the LanguageTooler grammar checker that's listed among Thunderbird's add-ons but I've seen reports on Reddit saying that it's only FOC for a limited time, after which you need to stump up a monthly fee,

Does anyone know of a cheaper alternative?
