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 right click then i see a huge list of options i never had before, and open in next tab, copy and paste are no longer working. Added a screenshot of half the list of options i see when right clicking. It includes copy and mut and full screen options for video that i never had before.

135.0.1 (64-bit) on Win11

I am (again) running into trouble with spelling.

I got this offered to me: https://www.google.com/search?client=ubuntu-sn&channel=fs&q=how+to+set+dictionary+in+firefox

Doesn't quite work. Wrong things declared, etc.

I see a "badly spelt" word. Double click, go to add dictionary.

To the best of my knowledge, it is installed. Others point me to about:config spellcheck.dictionary

But that is not really offered to me when I am typing the name. So probably doesn't exist.

I'm trying ITMT, but would like some help please.

Hello. This question concerns the Windows 11 desktop version of Firefox.

I have long used the Home and End keys on my extended keyboard to scroll to the very top of any given page in Firefox (Home) or to the very bottom of that page (End).

But, lately, I notice that, for no reason I can figure out, Firefox no longer responds to those shortcuts. Now, when I tap Home or End, the page may, at first, scroll up or down slightly but not to the top or bottom. If I press Home or End again, nothing happens at all.

Sometimes, if I press Ctrl + Home simultaneously or Ctrl + End the page will scroll to the top or bottom respectively.

Why has Firefox's behavior apparently changed? Is there an issue with my keyboard or operating system settings? (I use a Logitech G915 keyboard.)

Please let me know how to restore Firefox's shortcut functionality, where I can tap just Home to scroll to the top of a page or only End to scroll to the bottom of a page.

Thanks and be well.

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.

Can we get a setting that disable the Quick Find feature or at least its keyboard shortcut.

It breaks keyboard shortcuts on multiple sites, as it is often used to select the search bar(Youtube, Github, ...)

Hello- Wondering how to turn off the "skip to main content" that continually pops-up on some web sites. This is a problem on a single Firefox installation and I cannot figure out which setting this could be.

Thanks in advance! -BD

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.

I have come across some people who ask about the thickness of scrollbars.

Do you find the scrollbars are just too thin and difficult to select because your eyesight is not so good or maybe you have less ease in controlling the mouse? If yes then the following information may be of help.

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

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 ?

Doing a "find" ends up showing a greenish (so I'm told) background with white text. Want to guess which "find" in the attached image is difficult for me to find?

What I would like: Find (focus): yellow text on black background Find All: white text on black background

Yes, of course it would be nice if that would auto switch to black on yellow if the website default is black background.

I can hack userContent.css and get the selection function to work:

/* General highlight (for text selection, etc.) */

selection {

   background: #FFFF00 !important;  /* Yellow background */
   color: #000000 !important;       /* Black text */

}

I can hack userContent.css and get the Find All (sans the focus) to work.

But firefox always provides the focus with white on green. Even if I do something like this:

/* Customize the color of highlighted search text */ input[type="search"]:focus::selection {

   background: #FFFF00 !important;  /* Yellow background */
   color: #000000 !important;       /* Black text */

}

I tried several themes. No change. I tried changing Windows Preferences. No change.

There must be a way to make this "find" feature useful for me.

I'm currently using FF 134.0.2 on a Mac running Sonoma 14.6.1. I'm unable to use the Find shortcut (⌘ + f), but I am able to use other shortcuts in Sheets: ⌘ + c, ⌘ + v, ⌘ + Option + m. That shortcut operates as expected on other sites, opening the Find pop-up at the bottom of the browser. It's not working within Sheets to search a spreadsheet or at the browser-level when on a Sheets tab.

Any idea why that one shortcut isn't working?

Hi,

On MacOS, in order to set keyboard shortcut, I need to know the exact name for the feature. But I can't find tab navigations in Firefox's menu.

For example, in Chrome, they have a menu called "Tab" and there is "Select Next Tab" and "Select Previous Tab" in the menu. That are the names I need to set keyboard shortcut. But I can't find the equivalent in Firefox.

From the screenshot, the keyboard shortcut works for Chrome, but not working for Firefox as I don't have the exact name for tab navigation.

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.
