Thunderbird Support Forum

I am running Thunderbird version 115.4.1 on the Windows 11 system. Having Thunderbird active (even in the background or minimised) stops the Windows key from working. How can I get the Windows key to work normally without closing down and exiting Thunderbird?

Our Thunderbird is set up with 2 email accounts - Gmail & Cox cable. Actually 3 as my wife also uses TB for her Cox emails. Cox is moving over to Yahoo. Not a fan of Yahoo. Eventually I will either set up another Gmail account (cox was for subscriptions or when a business needs an email address) and my has a Gmail already, but she does not use TB for that as for her Cox is her main email.

So can I delete our Cox emails thru Cox web email site without losing our emails currently in TB? And will that mess things up as TB sends and receives email from cox cable?

Any tips and suggestions much appreciated.

Need to increase the spacing between messages in the message list window in Thunderbird. The solution provided in the forum thread "https://support.mozilla.org/en-US/questions/1314785" is not helpful.

duplicate of /questions/1438116 thread. Also it is Thunderbird and not Mozilla.

Connect my server to Mozilla. I need my Mozilla reached through AOL now. Please help me back into Mozilla.

Can I upgrade my Thunderbird 115.3.1 from 32 bit to 64 bit?

My Thunderbird has recently automatically updated to V115.3.1 but remains 32 bit. When I go to the Thunderbird download page there doesn't appear to be a choice of version.

In the past, I had followed this post and created the userChrome.css file so that when I have my emails shown in Table View, if one email within a thread is unread, the whole thread is collapsed, but the subject line remains in bold.

With this latest Thunderbird update to version 115.13.1 I have lost the functionality; now the subject line of the collapsed thread shows as underlined. How can I go back to my preferred bold view?

Thanks

HELP HELP HELP Duplicates continue to be generated as of latest Thunderbird Version 115.6.1. Final Solution?? Running on my MacOS Ventura 13.6.3 (22G436). Fully updated and kept as my babe!! Same as my Thunderbird. Using the [**Remove duplicates...**] official tool to fix it, but continues to appear always after some time.

Use a lot of dayly maintenance on my mails, creating _new-folders_ continuously and moving mails depending on subjects as needed. Continuously maintaining, Always _empty-trash_ followed immediately by _compact-folders_ Always try to do weekly backups.

Duplicates Still never ended since so long been reported!! Any way to fix the issue once and forever??

Do not need/want to suffer a complete platform crash on my loved mailer. Would be a complete disaster. Obviously I keep on backing up once per week.

Thanks a million if you try to help, and kudos if you solve it. Take care.

I've just installed TB 115.6 on my MacBook to see if I like it better than Apple Mail. There is one thing that seems weird to me. Fonts are displayed larger in the Read window than in the Write and Reply windows.

These are my font settings: Default font: Helvetica, size 14 Composition, HTML Style: font: variable width, size: medium

Now if I send an e-mail to myself the font looks larger once I receive the message than what it looked like when I was composing it. And then if I reply to this message the font becomes smaller again in the Reply window.

The font in the Write window has the exact same appearance as in Apple Mail where I also defined Helvetica 14 as the default font. So my suspicion is that the fonts are somehow scaled up in the Read window. But why? And how to change it so that the same font looks the same everywhere?

My thunderbird works okay, but when I select emails from imbox folder to delete it takes too long. I researched to find the problem and the only option I found was to add an exclusion to the profile folder on my windows security antivirus. Now I can select emails from the imbox and delete them without a problem, but my concern is if I will be vulnerable to virus.

I desperately (sobbing here) need someone to hold my hand and walk me through this!!! I uninstalled the newest version (115) and installed the previous version (102) because of an outgoing mail problem. It gave me a warning that the newer version changed my profiles and it's not compatible so I downloaded the new version again. The import screen doesn't look anything like what it says in the help files. I don't have an option for importing from a previous version.

Please rescue me. I run a nonprofit and I have deadlines and meetings next week that I was supposed to make arrangements for and I've been dealing with this for almost a week.

My friend has been using Thunderbird for a long time. Recently I installed her new PC and restored her account profile using the profile folder on her old PC. So far so good. The problem is that her mails are not organized in folders on the mail server but she has a whole collection of folders in her Thunderbird mail client and is concerned about loosing her mails if the new PC (or the disk) would crash at some point. Of course she could just re-install Thunderbird after fixing the crash problem and sync with the mail server, but then the folder structure would be lost. First I considered using a back-up program to keep a back-up of her Thunderbird profile using cloud storage. My second thought (should have been my first thought...) is that she already has a back-up, namely the mail server. The ISP does a better job than any local back-up program to keep her mails safe. Only the missing folder structure remains a concern. So here is the question: if I change the setting to sync all folders with the mail server, what will happen: 1 - the folders in Thunderbird will disappear (only the folders, not the mails) because there are no folders on the mail server 2 - the folder structure from Thunderbird will be mirrorred on the ISP's mail server. Which one is it?

The latest version of Thunderbird changed the top menu, and I see a "Get Messages" button, but can't find "Send Unsent Messages" as a function anywhere. I've tried customizing the menu, and I've looked through older help discussions for any ideas, and I've prowled through the settings menus and can't seem to find it. I've also tried right-clicking on things - no joy. I have a message waiting to go out in the Outbox, but no way to send it except Redirect.

Thanks in advance, for any help or ideas!

Thunderbird has changed one of my folders. This now has a different icon (see snip) and I cannot delete it as there is no option. Is it something that I've done and how do I correct it please. Many thanks

When I delete 1 email, it happens quickly. When I delete 5 emails, it takes about 10 seconds. When I delete 40 emails, it takes 2+ minutes, when I delete 100+ emails, it takes 7+ minutes. What's going on? Seems to me emails, no matter how many I delete, should be deleted very quickly. What can I do to speed up the delete process?

Thunderbird’s connection to one of my gmail accounts failed today.

I removed the account and then tried to add it again to Thunderbird.

When logging in using a Google generated App password, I receive the following message:

"400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

OAuth2 is in place, and I’ve carried out all other recommended checks I can find on your website. My other Gmail accounts are working fine.

Please can you help? Many thanks.

I have spoken to my ISP and its confirmed, as have I, that I can log on to its website and successfully download my emails so the problem "must" lie with Thunderbird. I am not very technically inclined so would appreciate some advice please, thank you. My ISP technical person (at iiNet Australia) did say they were receiving a lot of phone calls today about email and "blamed" it on changes to Outlook? If this helps. Regards.

Yesterday I tried the 115 (Supernova) and I was disappointed because of the toolbar on top of the TB window: I think that you should let the user choose where put any toolbar, and I didn't find the way to move in its "classical" place (not at top but below the menu). There is a way to do it? And if not, please consider to give it as soon as possible.

I think at some point I was able to send a private message. Or maybe it was just a reply to a private message that was sent to me. I remember something about clicking on a person's picture.

Thanks is advance for yoiur help. SweetTasha
