I was a satisfied user of the Thunderbird e-mail client. I especially enjoyed the ability to toggle into darkmode when browsing and reading my e-mail. The previous toggle I used to activate that feature is missing, and I cannot locate a work around to turn it back on. Any assistance would be greatly appreciated. Thanks

Firefox recently had an update, and now when I am uploading files, I can't double click to upload selected files. I have to first select the file, and then click the open button.

Before the latest Firefox update, I could simply double click on files to upload. This workflow was much faster.

If I go to about:config, and search for: widget.use-xdg-desktop-portal.file-picker, I can change the value from 0 to 2, and then I can upload files by double clicking. However, then Firefox forgets my last upload location, and always opens in the home folder.

If I set it back to 0, it remembers my last upload location, but I can't double click to open files.

My current Firefox version is 152.0.1. Any help would be appreciated. Thanks.

Wanted to change the shortcut Alt + number to Ctrl + number to go to Tab 1-8 (got used to it in Chrome and Edge).

Found this https://support.mozilla.org/en-US/kb/customize-keyboard-shortcuts-firefox and wanted to try it. about:keyboard did not work and showed that the address doesn't look right.

Oh yeah, my device is running Linux Mint Cinnamon 22.3.

Many times, I have a conversation with many messages. I may want to sort the array of conversation fields on any field. Currently, if I click on any field name, the conversation collapses.

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.

i want to be able to change the hotkey corresponding to go to left/right tab which the default is Ctrl+Pg Up/Dn in my lenovo thinkpad keyboard. and in about:keyboard that option is not available, in fact the hotkey isnt even mentioned

Hi! I use Thunderbird at home, but at work I have to use Outlook. This M$ sh... uses Ctrl-Q to mark emails as read. After a long day at work, I go home, sit down at my computer, and automatically keep pressing Ctrl-Q instead of R. I'm sure I'm not alone in having this problem. Could you please allow users to choose which hotkey exits Thunderbird, or at least disable the hotkey?

Using a new, clean install of Xubuntu 26.04, with thunderbird 140.10.2esr 64 bit, ubuntu snap build 1.0. In settings: play a sound when new message arrives, no sound is heard. When clicking "play" to test the sound, there is no sound. Also, if "use the following sound file" is checked, there is no sound when "play" is clicked. (I have tried various .wav and .mp3 files.) I have installed pipewire-alsa, but that didn't help. Any ideas?

Threading - why does it keep coming back? I have just realised it's back again on my Thunderbird and I never knowingly turned it back on.

Why does Mozilla keep trying to force it on users?

This has been an annoyance for users for several years now and the message has still not got through it would seem.

For an open and user-facing organisation, this is strange behaviour that I just do not comprehend. Include it if you want, but make it optional and easily so.

I know this is only the community forum, not Mozilla, but one would think that a wise organisation would keep an eye on what their customers were saying & feeling.

- Linux ver 140.7.1esr (64 bit) my folders are now out of alphabetic order among other things Trash us now under 'T' instead of grouped near the sent folder and my Computer folder has a mind of it's own. It's not under C even after I changed the name. It is just stuck. Wha? tnx

For the last 2 months I have been working to configure Thunderbird to fully replace my Gmail UI usage after their recent change to workspace options and using data to train gemini. When you deactivate those gmail features the first thing you lose are tabs for your Inbox, your Updates and your Promotions.

So far I have used tags, ThunderAI, Ollama and a locally hosted LLM to replicate the sorting of my inbox, but now I would like to be able to configure the Thunderbird UI to allow separate tabs in the menu bar for different folders, in this case Inbox, Updates and Promotions. With Inbox still being the gmail hosted main inbox and Updates and Promotions now being local folders stored in my local thunderbird installation.

Can the Thunderbird UI be configured to display folders as tabs as a default setting? I tried the "folder selection" button under customize on the toolbar but that just gives me a drop down, which is not what I want.

I want to delete Preview Links. I tried going to Settings>General>Browsing, however, there is no "Browsing" section. I have a Linux Mint. I do NOT want Preview Links. Thank you.

Hello,

I am using Thunderbird on my arm64 Linux machines (Raspberry Pi 4 and 5 and my Odroid C2) and I want Thunderbird to send the correct platform information in the User-Agent line. After enabling Thunderbird to sent the full User-Agent line the following information is currently sent:

User agent:Mozilla/5.0 (X11; Linux x86_64; rv:140.0) Gecko/20100101 Firefox/140.0 Thunderbird/140.9.0

Everything is correct except for 'x86_64'. I would like to have sent the actual 'arm64' information because I'm proud using my small ARM64 machines as workstations and as a replacement for classic PCs and I do want to have this information distributed with every mail I am sending with Thunderbird.

Is there an easy way to get the correct information about my arm64 machines into the User agent line?

I am happy for any advice and help.

Kind regards,

     Roland

This is the only place I thought might match my request.

Well, maybe not so much support, but a request.

Any chance of adding a dedicated notes tab?

There are times I need to jot down ideas on an email, or quickly need to have data available readily.

DON'T want to have to open another application JUST to take down info.

Thank you for a great product.
