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.

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

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

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?

- 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

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.

For a long tome Chrome use to be my go to browser, but with all the recent changes and google buckling to legislation changes, I returned to Firefox as my primary browser. You see, because proxy settings can be set within the browser instead of system wide as with others, I primarily used Firefox to access private networks I was given access to. I still use Firefox for this, but mow for everything else too.

I see that there can be multiple profiles set up, which I hope would allow me to quickly swap between proxied connections and non-proxied connections. The problem I ave found, is how hard it was to find this setting with the latest iteration of firefox. It used to be a simple matter of scrolling all the way to the bottom of the settings screen, now I've had to hunt high and low just to find it. Whilst I have mentioned multiple profiles already, if this does not allow me to quickly swap then its pointless. So, can we PLEASE have the proxy page put back where it was, nice and easily accessible,

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

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 spend the last hour or so in sheer panic and doubting my sanitiy as an email I was just reading disappeared from every mailbox I have here (I have 8 mailboxes in Thunderbird) . Also for whatever reason search is missing from the title bar.

The email was "archived" by Thunderbird inthe "Local Folders" I never use local folders as local folders is silly in 2026 imo. I have my own mailserver which is perfectly save and backuped and stuf I don't need yet another location were mail can hide.

Anyway that was a bit of a rant. This would not have happend if this sille ¨Local Folders" didn´t exist at all. But I seem unable to get rid of it.

How do I remove ¨Local Folders" from Thunderbird?

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?

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.

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.
