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!

Much of Thunderbird is too small, too faint, or in fonts that are too hard for me to read.

I've found some user css that helps with some of that. It helps with the headers and lists. But it doesn't affect message contents, even in plain text mode, or settings.

Okay, so why don't I just use the built-in font settings? Because:

1. There are different settings for different parts of the interface, and it can be hard to predict how they'll interact.

2. I need to increase the size of most text, not all. I don't want or need to increase the sizes of some larger text. I don't have enough screen space for it either.

3. I need to increase the *weight* of most text. There's a fad for thin "elegant" fonts, and I just can't read these. I currently use css to make headers bold, and make unread headers red for contrast.

4. I often need to change the fonts, too. Thunderbird seems to use the "Other Writing Systems" for message contents, which is a pain, because I need to use that for another writing system, too.

With the new version of TB the address book has become unusable. It is not White Text on white background. I can't find any settings to reset or apply a theme or fix the colors of the text within the address book. There are many settings and themes that one could apply to the mailbox but if one can't see the address book that pretty much it useless to try to use the email.

How does one just set up the ENTIRE program to apply a theme? Or can we get a working White and Dark themes that address all Text and All backgrounds to make them legible so there are at least useful. TB has become very frustrating. Sorry to rant but before the big changes to use native Darkmode it was really good email client but like so many that try to embrace the darkmode trend (which isn't a bad idea) they are falling short of addressing the entire product.

Any help to address the color issues in the address book would be greatly appreciated.

Windows 10 on PC with Thunderbird 140.1.0esr (64-bit) Since the last update, the background on my Tbird messages list, email panel and in my compose email panel have turned from my eye-friendly light grey to glaring white and this is literally causing me a headache and a "flimmer" in my eyes (common in people with blue eyes). All other programs in Windows show me the light grey background as they should, it's Thunderbird itself which isn't picking up the light grey. The only place in all the tools and settings menus that I was able to find ANYTHING about background colour was (three bars) -> tools -> Settings -> HTML Style [ ] Use reader's default colours <- makes no difference whether this box is marked or not Beneath that: Text Colour is set to black. Background colour is set to light grey. There is no way to Save the settings page, so one presumes they are automatically saved. Restart (done several times) Thunderbird - still this blasted white background. I do not use HTML for emails, I use plain text. Could someone please tell me how I can get my light grey background back ?

Hi, when I want to zoom in to the website page, I cant seem to find the horizontal scroll, thus I cant see the left side of the page that I zoomed in. Please make the horizontal scroll available. Thank you.

For the last 5 or 6 days when I go to block a spam sender I get this message "We couldn't block this sender. Please try again later." It happens on every email address I try to block - so far, about a dozen or so.

Is this a temporary glitch?

Many thanks for looking into this for me!

Sometimes, when I want to use the Take a Screenshot function (on my toolbar) to save a long section of a page, after selecting what I want and scrolling down to the Download button, the process positions the page's floating 'identification' bar across the the middle of the picture. Is there a way to set a keyboard shortcut to trigger the download command after making the selection, without the need to scroll down to see the button? This would greatly simplify the process. In some limited searching and testing, I haven't found anything that accomplishes this.

I have attached a screenshot of a page to serve as an example of how the bar is superimposed.

FWIW, this system is still running Windows 7, Firefox 115.22.0 esr.

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 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.

How do I report an issue with the way NVDA and Thunderbird interact? When I tab, I can't out of a link, and the focus does not move. If I tab to a link in a message then arrow down, I am where I expect, but then if I go to the top of the message, the tab focus remains where it was when I last hit the tab key. This is not standard behavior, but everyone else I've talked to seems to think it's behaving normally and has no tips for me on how to fix it.

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 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

in latest version of firefox this https://support.mozilla.org/en-US/questions/1367908 no longer works

Hi,

On my desktop, thunderbird does an awesome job cutting spam. While on the mobile its terrible, not just are most spam mails coming thru but some legit emails are getting flagged. Is there some way to make it mimic the desktop.

Thanks in advance

I own a website that has chat rooms for each of my advisors. As of 2 days ago they are all having issues. I have them login with Firefox but now asking them to use Google Chrome...............low and behold it works

Whats the issue as i believe it started with the latest Firefox update

Thanks so much

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 Verizon FIOS and have been able to receive cable channels on my laptop until recently. Now I cannot access them without a sign-in which leads to some sort of error that I don't understand. Any help?

I have recently migrated to Firefox from Chrome.

I cannot paste images (screenshots) directly into my Outlook emails.

I can insert a picture file but this is way less convenient than taking a screenshot via the Snipping Tool and pasting directly into my emails.

I cannot find any setting or configuration that would enable this functionality.

This functionality sure worked in that other browser.
