Thunderbird message header pane is so large that I can't read messages. The top 2/3rd of my screen has the list of messages, header bar, files, etc. The bottom 1/3 is for the actual email message, but the header takes up nearly half of that with just the "From", "To", and "Subject lines taking up more than half of that space. Depending on the text of the html message, sometimes I can only read one line at a time, which makes it difficult to actually comprehend a message while scrolling, particularly if it's a long message. I can't resize it to make it larger, though I can make it smaller. My eyesight isn't quite as good as it used to be so I use a larger font than I used to, ie: 12pt rather than 10pt, and that makes it worse. Any suggestions?

Thanks to the help received here and in the Reddit group I've been able to transfer almost all of my old colour and layout tweaks to a new intallation of Firefox (v133) on a new PC (running Windows 10). There's one thing that I haven't succeeded with though: I'd like to change the colour of the text in a tab when that tab becomes the active one.

This is the coding I'm using to change the tab's background colour when it's selected:

1. TabsToolbar .tab-background[selected]{

background: white !important; }

This works perfectly. But when I tried adding the line

color: black !important;

It had no effect. I'd be grateful for any thoughts. Many thanks.

I am new to Thunderbird and apologize for my question! After restarting my MacBook, it works as it should.

I don't need any help! Best regards, Thomas Merry Christmas!

In the signature in HTML format, a space is automatically inserted after a hyphen. How can I prevent this?

Example: Correct: domain-xxxxx.com This is how it is saved as an HTML file.

However, this is how it actually looks after restarting: Incorrect: domain- xxxxx.com

Thank you very much! Best regards, Thomas

The font size in "Manage Bookmarks" is way too large, both in the sections list menu on the left and the list of bookmarks. I checked my userChrome.css file as well as the layout.css.devPixelsPerPx entry in about:config and there's nothing there to explain why only the "Manage Bookmarks" text is so large.

It's possible I changed a setting somewhere that's causing this. But I'm stumped re: what setting might be controlling the font size in only that UI. All other Firefox text sizes are good.

Thanks to anyone who knows where I should be looking

Firefox 134.0.1 (64-bit) Windows 10

I want to have my sent messages in the sent folder on my main account, but Thunderbird insists on putting them in a Save folder in Local Messages. I've changed the settings several times in my account, but the change won't 'stick'

Hi folks

I have a particularly infuriating problem. A few weeks back, Firefox stopped displaying my usernames and passwords whenever I wanted to log into a site. This coincided with my installing BitDefender, although I don't know why.

Through googling I eventually realised I could go into about:config to fix this. signon.rememberSignons displays as false, when I turn it to true it fixes the issue.

But here is the problem I can't solve. Everytime I restart firefox or my PC / Mac (I am using both, with a syncronised account on both windows and MacOS) it sets signon.rememberSignons to false AGAIN. Which means every single time I browse I have to go into about:config and fix this. Maddening.

Please can you help?

My friend recommended this browser to me. When I tried to customize it, I couldn't find an option to change the hotkeys to my preference. I consider this feature important since I use it for work. Can I do this somehow, and is there any plan to add such a feature to the settings?

background-image: url("file:///C:/Tools/FF/FFbkgnd01.jpg") !important;

Used to work, and does work in the regular version of the desktop app, but no longer works in the beta for desktop 135.0b9, says: "Could not load the image"

Thunderbird refuses colored text on new Lenovo 17" Idealpad and adds asterisks not written by the author. Example message test: bbbbbbbbbbbbsssssssss ggggggggggggg***234*5678,56 *<==============* The written numbers and the arrow were colored red. No asterisks were written in the message sent. When writing, colors appeared correctly in messages with no asterisks on screen. However, no colors appear and asterisks are added in recorded messages sent and received on the PC. The Lenovo PC works OK in general, so it must be a Thunderbird configuration/function problem on my PC as the message is correctly received with colors without asterisks on my mobile phone. Can you help me correct this PC anomaly? Many thanks

I recently updated from Windows 10 to Windows 11 and have been using Thunderbird for my 4 email accounts for about a decade. Since the update, all my sent messages have a > sign next to them which I have to click on to view the various messages sent to the same person, with the latest message chronologically displayed near the bottom of the grouping. My thread option has been unselected. This is a new and unwanted layout and I only wish to see my emails displayed individually and chronologically, with the most recent near the top. How do I remove these groupings with the > icons and just see each message displayed individually? My frantic research only points to installing/selecting an 'add on' perhaps. I just want to see my sent emails individually like I have for the last decade as well as in my folders from previous years. SEND HELP!

Hello, In a recent upgrade to Thunderbird Mac OS x146.0.1 (aarch64), the FILTER selection options on some drop down menus are now blank. Example: "Priority" "Status"

These drop down menus now show no options (eg. read,)

I've two screen shots to illustrate.

Thanks for looking into this.

Hello,

I wanted to customize my Firefox new tab with a local HTML file, such as "/path/to/my/index.html". It was possible to use this workaround: https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main

Which implied a configuration file (sometimes named "autoconfig.cfg", "firefox.cfg", "local-settings.cfg" depending on the guide since the name is arbitrary) with javascript code. In the new Firefox 136, this code fails to execute due to a new API being used.

If you want to customize your new tab, follow the previous guide, but on the configuration file write this code instead:

// My new tab
try {
  const ff = {};
  ChromeUtils.defineESModuleGetters(ff, {AboutNewTab: "resource:///modules/AboutNewTab.sys.mjs"});
  ff.AboutNewTab.newTabURL = 'file:///path/to/my/index.html';
} catch (e) {ChromeUtils.reportError(e);}

Note that the file must start with a comment

Adapting the "/path/to/my/index.html" to your needs.

Thanks to @mkaply (github) on this thread https://github.com/mozilla/policy-templates/discussions/1190 for the new API method.

I post this here in case someone has the same issue, because is quite recent and hard to find on the internet.

Hi all,

In a now deleted Windows 10 Thunderbird setup, we used the Config Editor to globally set Delivery Status Notifications as true.

This ensured that every email attempted to return a delivery notification without the user having to manually request one when composing an email.

We have since shifted all our computers to Linux Mint, but I am unable to find this variable in the Config Editor.

Has this been removed?

Thanks! b

the settings ExtessionSettings does not show up to be able to modify even tho it is on the ADMX file (5.11)? Should I use the older Extensions policies? I want to install and pin an extension from the store.

I've imported/exported everything I could from a Win10 to a Win11 one. I then went to the toolbars under "view" and made sure they were all checked. Next, I clicked on "customize" and selected (single click) what I wanted to add to my toolbars in the mail window. The "save option" was greyed out. How do I save these to my toolbars?
