I don't wish to use the calendar that comes with Thunderbird, but instead continuing with my Macintosh iCal.

1) How do I switch off the Thunderbird calendar function? 2) How do I get the calendar invitations sent to me as an ICS file attachments, that I can open in Mac iCal. Just like in Airmail and in Microsoft Outlook.

My Tbird email was not working, so I tried a "clean re-install" as recommended on your website. I lost everything, contacts, archive, pics, email.. .years worth. Please tell me I can retrieve them.

Thank you,

Pat

I use Thunderbird 140.11.1esr with Ubuntu 24.04. I also use LibreOffice 26.2.

When using LibreOffice, if I want to delete a number of contiguous characters, I put the cursor at the start of the characters I want to delete, press the delete key and hold it. Holding down the delete key means that delete works its way through all the characters I want to delete.

When using Thunderbird, if I want to delete a number of emails, pressing down and holding the delete key doesn't result in the deletion of a number of emails. Instead, I have to keep pressing delete again and again.

Is there some setting in Thunderbird that I can change that will result in delete automatically working its way through all the emails I want to delete?

Thanks,

Leslie

I NEVER want to mark all my email as read. How can I disable that functionality? I look forward to being able to also get rid of shortcuts that do not require ctrl, alt, or shift.

Migrated my data from old MacBook to new MacBook, and got a message of a damaged Thunderbird app. Deleted the app. Thus, I cannot retrieve personal data on my old Mac. I do have a gmail account, but my preference always has ben to use Thunderbird. How do I proceed?

It says that the folder is in use by some other operation. I tried a Force Quit and a restart and neither worked. Please help.

His OS is 10.13 and his TB is 115.18.0. He kept the old Mini because he was running an ancient version of Photoshop that ran a plugin that is not available for Adobe Creative Cloud.

Robert was a sculptor who did large kinetic work and much of his work is still on that computer.

I am still getting his email on my iPhone, so I don't know what is going on. Unfortunately, I haven't saved his email history on my iPhone so when someone answered a similar problem a couple of years ago, the only place that email would reside is in Robert's inbox on his Mini, which I can't open.

Many thanks for your help.

I use Thunderbird with Threaded View enabled and would like to keep using it.

What I am looking for is a way to have Thunderbird automatically keep older threads collapsed, while allowing threads that contain new or unread messages to remain expanded or become expanded automatically.

For example, a thread receives a new message - it is fine for that thread to be expanded. All other existing threads without new activity should remain collapsed. When Thunderbird is restarted, I would like older threads to stay collapsed rather than having many previously viewed threads expanded.

Is there a setting, hidden preference, add-on, or workaround that provides this behavior?

I am using Thunderbird on Kubuntu Linux.

It's possible to drag/drop contacts from To to CC or BCC.

It should be possible to do so across messages open in separate windows.

But when I try it, it fails.

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?

A weird thing has started happening to my Thunderbird inbox in the last couple of days. Emails are showing as from a totally different sender. For example, a Google search on Sondheim has been "sent" by EDF (my electricity supplier) and some Groupon emails are showing as coming from people I correspond with. Also a Keto bread recipe from a low carb group I belong to has been "sent" by one of my work clients! More weirdly, I copied them into a subfolder on my inbox and they then appeared correctly. I have tried repairing the folder but it made no difference.

TB is hung up on my late husband's computer and none of the suggestions made has released it. Current advisors are Windows people and this is an old Mac Mini running OS 10.13. One of your advisors solved a similar problem two years ago and David told me I could open that message by clicking on Robert as question originator. Please email mr at X@perless.com if you have comments or questions.

To whom it concerns, It just happened yesterday June 11,2026. I put in my password to my e-mail to open it and it stated that my e-mail account is being processed. Said to wait until processing is complete to get messages. I have never had this issue, I been with Thunder Bird e-mail for years. It isn't even showing my e-mails that I had in my inbox on my e-mail. If you can please help, I need my e-mail up and going. Thank you, Chris Note, it also said that Thunder Bird had crashed in a box, they wanted to know what page I was on. I am not understanding this.

I had a great Thunderbird Emoji add-on that is no longer supported. This.

https://services.addons.thunderbird.net/en-US/thunderbird/addon/emojiaddin/

It no longer works on updated Thunderbird, and shows it hasn't been updated since 2022. I'm on Thunderbird 140.11 on my Linux Mint. The image the plugin inserts in message bodies is broken. Is there another/similar add-on?

Hello,

I have found that once an email is put in the trash it will automatically be removed/deleted from the trash.

Today is June 14th and there are no emails in my trash folder older than June 9th.

Is there an account setting in Thunderbird for how long an email once in the trash folder will remain there?

Note, this behavior only occurs in the trash folder.

Using Mac Tahoe latest and Thunderbird 140.11.1esr (aarch64)

Thanks so much.

I have 4 seperate email addresses in Thunderbird. Only one of them has this problem and I would like to resolve it. When I send an email, the copy goes into "All Files" and not into the "Sent" email; folder. Which setting do I need to change to put it right please?

I use Thunderbird on a PC. It has began to open evry e-mail I select as a pop-up window. This is unusual for me, and I do not want it. I just want to open the e-mail inside those windows that already exist on the screen. It has been like that before. In settings I have selected to open e-mails in an "existing window" Is this korekt? Finally one more question: can I write in Danish here? It would be easyer for me to explain my problem in danish.

After click, Ask a question, a banner pops up saying my post is awaiting approval by a moderator. Why? What did I do or say that appeared so negative as to require approval first? IMO, it takes time for a Mod to mod it. Then it goes out for some people to see. It's not good for business if there is no wait time, and it a waste of time, if the problem asked, has a answer in a holding pattern, that goes in to a holding pattern again if/when the Post is permitted. Very odd..
