Thunderbird for Android Community Forum

I exported my settings from desktop thunderbird when setting up Thunderbird Android 20 but discovered it was automatically marking messages as read. That makes it difficult to have a peek at messages when I'm out (in case there's something urgent) but still see those messages as unread when I return to the desktop.

https://support.mozilla.org/en-US/questions/1504592 claims to have found the option to do that, but it's an old message that has been archived without ever saying where that option was found. I've tried settings search as well as a visual search of all settings without seeing a relevant option.

Does that option actually exist? Or do I have to go back to K9 (which, at least in v19, had that option)?

On my Samsung A05 Thunderbird does not show received email dates only the day. This is useless for finding emails going back more than a week or two. I don't care what day of the week it was received, just the date and time. Earlier solution offered (via message lists) not in any of my menus so cannot use. Please advise how to show dates. Current OS Android 15 A055FXXSHDZF1/ A055FOJMHDZF1 / A055FXXSHDZF1 with security patch level: 5 June 2026 Also cannot find support/about option in the settings menu to show the Thunderbird version.

Please add an UNDO feature to the Android version.

It has happened to me multiple times that when trying to scroll (esp in the bus) it registers as a swipe & deletes a message.

and then it's really hard to scan the trash to figure out which message it was

at the same time, i don't want to be asked for confirmation *every* time i delete something - I'll spend as much time "confirming" as deleting messages.

So the ideal in an undo button somewhere in the interface where a can undo the last action (from a subset, since I'm guessing not every action can be undone). The desktop version has it, hopefully it can be migrated to the android version.

thank you

1. 1 there should be an option to put the menu with the delete button at the bottom, not top.
2. 2 Unified inbox is great, but why not unified everything. Unified spam,.sent, deleted etc. Blue mail does it and it's very useful.

Those are the 2 main things. Anything else is not important but nice. E.g.

1. 3 Options for a bit more colour or ability to colour things, like accounts or senders.
2. 4 One click unsubscribe for emails

Other than that it's utterly awesome and feels very stable, unlike the new release of Blue Mail.

Sometimes I got a problem with Gmail where I get the error "Too many simultaneous connections", both desktop and Android. I found that Gmail servers support 15 connections. I could reduce the number of connections for desktop in the config editor, but I would like how to do that in the Android app. Some times it creates a lot of connections, and I think the numbers stack up together with dead connection when I reboot my router and get a new IP, so I'm wondering how to set to get just one or two simultaneous connections on Android.

The Delete button (I've just begun using Thunderbird for Android) sends email to Delete-land: gone for good. There is no way to reprogram it to send to Trash. One can, alternatively, hide it on the main screen by setting swipes left and right to None. But it is still there in the Read screen....and potentially dangerous. If you try to set a swipe to Trash rather than Delete, there is no Trash option. So you have to set it to Move and choose Trash each time. This reduces the utility of Tbird Android and means you have to be extra-careful when reading emails.

Also, no way to reduce image sizes (by percentage) when attaching large picture files...unless you reduce them in advance in an image processing program.

I'm using Thunderbird for Android 19.2 from Google Play on Android 16.

When I try and send large-ish (around 1MB) messages they are not sent, and a notification "Failed to send some messages / Unable to Send message" appears.

This isn't a server restriction. The mail server it's connecting to is mine, and with a smaller message log entry "postfix/smtps/smtpd" appears. With larger messages no SMTP connection is attempted and no such message occurs.

How do I configure the size at which this occurs?

Hver gang jeg får mails i min indbakke så kræves det at jeg sletter dem ikke bare en gang, men to gange, før de væk fra indbakken. Tidligere har jeg kunnet slette en mail en enkelt gang - som i alle andre mailprogrammer - men nu skal jeg som sagt dobbelt - slette dem. Hvad kan jeg gøre for at annullere indstillinger om dobbelt - sletning. Kh Flemming

Since a few releases, when composing a message and selecting text, the highlight color is invisible in light mode. In dark mode the highlight color is a light blue. Is there a way to change the highlight color in light mode? Thank you.

I just got a Galaxy Tab S9 FE+ tablet as an alternative to bringing my heavy laptop on an upcoming trip. I've been using Thunderbird on my PC for very many years, and love it.

As seen by the attached photo, I was hoping that TB for Android would work and can be configured similarly as the desktop version, with my multiple email accounts showing up on the left side with the number of emails to be read, and the emails listed on top with the viewing pane on the bottom.

What I don't like is a single screen with all emails shown, not knowing what's new, and in what folder they're in. I've taken great pains to create message filters to sort all incoming emails, sorting emails into separate folders.

Am I missing something, some setting that would allow me to recreate my desktop version on my tablet. I choose the S9 FE+ for it's 12.4" display, so there's ample rook to visualize this desktop setup.

Any help and suggestions would be greatly appreciated.

Thanks, Bill

TB crashed so I uninstalled/reinstalled it. As part of the reinstallation, I selected the "load more" value as 1000 more. This was done rather casually and without any consideration. Afterwards, I thought perhaps this might slow Thunderbird down. Is that true? And how do I change "1000 more" to some other value? I've searched extensively but can't find a solution anywhere. Thanks, Ian

Hello all,

I installed Thunderbird for Android beta at my smartphone. After importing my account from the desktop version of Thunderbird I don't see the subfolders of my inbox. How can I show subfolders in the app for Android?

Kindest regards

The automated email from one sender states in the Inbox summary that the email client does not support HTML (TB app for Android). Presumably the message format is changed accordingly. I don't see a setting for incoming email formatting. Can you help? Inbox summary view and partial view of opened message below.

I set the Visible Message Actions to Delete and Move.

But I get Delete and Mark as Unread.

Move is far more important to me than Mark as Unread - why can't I see/control this?

I have unified inbox. If I want to view other folders e.g. sent them navigation is painful. Other android apps make navigation much simpler. Am I missing something

We read "If you are having trouble viewing the full width of an HTML email in Thunderbird for Android, you can either pinch and zoom or change the viewing mode. "

Well that involves moving back and forth for each and every line.

Sure, blame it on the sender for assuming we have a desktop computer.

But now it's too late, they've already sent it to us.

Gmail gets around this by reformatting the HTML to fit the screen size.

Or perhaps we could be allowed to see the plain text version of a multi-part MIME message, like Roundcube allows us to.

Hello,

after yahoo messed up their email beyond usability I am looking for an email client.

I like Thunderbird with it's neat and clean user interface. But even with 0 subject lines ans compact settings I only see 8 emails per screen on my 10" tablet.

Is there another setting that I have missed which would give me at least 20 emails per screen?

Also search is incredibly slow (one result every 1-3 seconds). Is that only because I just recently installed it?

Kind regards,
