Thunderbird 138/139, Windows 11 Pro 23H2. While composing a message, after a few lines the app freezes. Both the compose window and the main TB window freeze. Only opening the Windows Task manager allows me to close them. This did not happen with earlier versions.

If I save the message every few seconds while composing I can get most of the message back and continue after restarting TB. This behavior is the same in both the normal and troubleshooting TB modes. I can't even find a crash log to send to Mozilla.

Where shall I look next?

Thank you!

When I installed Firefox, I struggled to find a theme that was easy for me to see. So many had dark borders/backgrounds or busy backgrounds or transparent. It appears that I'm using the default at present and am happy with everything but the visibility of those little icons. Is there is a way to make them darker? Thanks

We have poor eyesight, so in vertical display mode, we could really benefit from having grid lines (at least horizontally) to visually distinguish each message. We have read various solutions on the Internet, but none seems to work at least not in dark theme mode, which is the default for a great many people with vision impairments (or just plain tired eyes). Perhaps some solutions that once worked have been uprooted, so to speak, during the course of Thunderbird updates.

We are used to having grid lines in Outlook (desktop). We are currently exploring switching to Thunderbird, but it needs to support our vision needs. For us, this capability is fundamental, not optional.

We are comfortable making config entries, creating and working in userChrome.css, and the like. We would be grateful for any guidance in this regard.

Thank you kindly!

This does not work anymore and I get an edit drop down with copy, paste etc It works on Chrome and Safari. I checked the config for "browser.fixup.alternate.suffix" and it is set to .com.

I noticed that the World Clock widget includes Pakistan Standard Time (PKT) but does not provide an option for Indian Standard Time (IST). This is surprising given that India has one of the world's largest internet user bases and a significantly larger population than many countries currently represented.

India operates on a unique UTC+5:30 time zone used by over 1.4 billion people, making it one of the most widely used time zones globally. The absence of IST while neighbouring time zones are available feels like a major oversight and reduces the usefulness of the widget for Indian users and anyone who regularly works with Indian colleagues, clients, friends, or family.

Please add Indian Standard Time (IST) to the World Clock widget as a standard option. Its inclusion would greatly improve the widgets global coverage and usability.

Hi there. I'm looking for a shortcut that takes me from the folderlist pane to the message pane and the first new message, when I'm on the inbox folder. The tab is not good. It moves between to many fields/options.

Within my Outlook.com email account i have an archive folder with 36 sub folders.

In the Thunderbird app for Android only 2 of these sub folders are visible.

I cannot find any setting that to resolve this issue

I just setup this firefox extension to help me manage my 800+ tabs - https://addons.mozilla.org/en-US/firefox/addon/simple-tab-groups/ . This might have even been causing Firefox to crash and my computer to restart, but I'll save that for a separate issue. The extension has some suggested shortcut keys, particularly Ctrl + Backtick and Ctrl + Shift + Backtick to switch between next and previous Tab groups. I tried to go to Manage Extension Shortcuts in settings, and tried to specify the keys Ctr + Backtick, but the input box would not accept the key. In fact it only seems to accept Ctrl + <alpha-numeric> key. or Ctrl + Alt + <alphanum>

Is there anyway to enable this? Most keys like Ctrl + alphabets appears to be already mapped by firefox's default mappings. my Ctrl + numbers are also similarly mapped by another tab extension to switch tabs.

Thanks, arun

Hello Everybody . I have used Thunderbird for a number of years and I like it and have supported it from time to time with donations . I am a person with dyslexia and their a lot of people with this problem . more than you would think . The one thing that I think would be nice is to have a speech to text as part of Thunderbird . It would be a big help to us with dyslexia . Thank you for letting me bend your ear .

I have 2 instances of Firefox: I use stable for all my professional work, and I use Developer Edition (Aurora Channel) for personal things. The stable branch works fine. In Aurora though, certain key combos will not work. This even persists in troubleshooting (safe) mode.

Specifically, it seems anything using both ctrl+alt will not register alt, only ctrl. alt, alt+shift, and ctrl+shift all seem to work fine, but ctrl+alt and ctrl+alt+shift do not. Again, this works fine in stable, so I am clueless as to why it doesn't work in my other instance.

Another detail is that this happens on multiple websites, not just one. The post prominent one is Google Sheets. In sheets, you can insert the date using `ctrl+;`, the time using `ctrl+shift+;`, and both using `ctrl+alt+shift+;`. Inserting them separately works fine, but both causes only one to insert.

With normal mice, when you scroll you typically scoll in steps which you feel as the mouse wheel feedback.

The issue here is with high resolution scroll wheels, whether that is a knob or a "frictionless" mouse wheel like on higher end logitech mice.

What happens: You slowly rotate the scroll wheel while nothing is happens in firefox, then you get to a certain point and firefox scolls one step, then you continue to slowly rotate the wheel, and eventually firefox scrolls another step.

What should happen: It continuously scolls as you rotate the wheel. This works in chromium browsers and other chromium based apps like discord, steam, etc, it also works in kde settings app, dolphin, okular, etc. But not firefox. It even works in terminal.

Both firefox and thunderbird are like this.

Is there a way to get this working or is it simply not supported in firefox? If so then feature request: get high res scoll wheels to work

I have a Samsung J5 with Android 9.

I have Firefox Beta version 139.0b10.

Has the issue of Firefox beta cutting off text between pages of the PDF file when printing to PDF files been resolved with the latest versions of Firefox beta?

Hi All,

I am installing Thunderbird from official GitHub releases and I am wondering why I am getting info from Obtainium that thunderbird-14.0 is something called "pseudo-release".

Can someone explain me this term regarding GitHub apk files? Is it OK to install it?

Since eclipse 140+ rolled out there is no longer a high contrast colour override, I dug through all the settings in case it was moved but I am either not seeing it or it's not there anymore. Does anyone have an option or work around for enabling high contrast without me having to roll back my version or install a different email client?

I do not know why but since yesterday I don't have the Orange Box in my Thunderbird home page to create a new message. I have to go into account and click on new message ( with a pen icon ). How do I get the orange box back. I have the orange area in the other pages like addresses, calendar, and the like, but not for new messages. How could I get it back because I installed a new copy of Thunderbird but it did not work. Thank you.
