Headers Font Size (Linux)

[BillTreloar]

Hi — Is there a way to adjust font size in the header portion of the screen? In my copy, it's a much smaller font than normal body text and as I get older it's increasingly difficult to read.

Thanks for this — but unfortunately, the page times out before displaying in either of my browsers. Are you in a position to troubleshoot that?

The Knowledge Base has been off-line for the last couple of days but should be available today or tomorrow.

I would also question why you’re seeing that. Do see the same issue if you launch the program in Mozilla Safe Mode?

I see the issue using safe mode in my version 88 on Fedora 33.

The article (thanks for suggesting the Way Back Machine!) shows four areas where I can change the font. But I don't know what they mean:
#folderTree > treechildren {font-size: 12px; font-family: Arial;}
#threadTree > treechildren {font-size: 12px; font-family: Arial;}
#dirTree > treechildren {font-size: 12px; font-family: Arial;}
#abResultsTree > treechildren {font-size: 12px; font-family: Arial;}

Can you translate those trees into plain English for me?

Where I want to increase font size is in the header section: the section above the message body that shows From, Subject, and To.

I guess you mean this (upper) part of the message pane framed in red in my screen shot:


You can use the following CSS code in a userChrome.css file:

Code: Select all

/*  Message Header font size  */
#msgHeaderView {
font-size: 13px !important; }

Adapt the number of pixels to your eyesight.

I have tried all of the suggestions here and nothing has worked. I can change the message text with View > Zoom, but nothing changes the header text, tree, etc. I have just checked, there is only the one userChrome.css file.
Running Thunderbird 78.14.0 (64-bit) on Linux Mint 20.2 Cinnamon
Any suggestions?
Thanks

Remember to set the toolkit.legacyUserProfileCustomizations.stylesheets preference to true, then restart.

I hadn't set that, but now I have it has still made no difference. I have looked at the troubleshooting link and a few others and they all seem to refer to Firefox and not Thunderbird, should it also work on Thunderbird?

Check if the userChrome.css file is really in the chrome folder in the correct profile folder.

Application menu button > Help > Troubleshooting Information > Update Folder > Open Folder
Application menu button > Help > Troubleshooting Information > Profile Folder > Open Folder (click here)

Try testing a single rule to see if the userChrome.css file is working correctly.

Code: Select all

/* Thunderbird userChrome.css */

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

* { background-color: orange !important; }

Remember you must restart the application for the changes to take effect.

Sorry I think I am missing something here.
Help > Troubleshooting Information - there is nothing called Update Folder or Profile Folder
The chrome file is ~/.thunderbird/zbmsmr81.default-release/chrome/userChrome.css
I have just replaced it with the code you suggested and restarted and it made no difference, I guess it should turn the background orange but it didn't
So I assume that the .css is not working but I have no idea why.
Ideas?

BrowseInTab (also on ATN) has zoom options for both global chrome font size and UI elements (folder list, message list, toolbars, tabs, icons) as well as per tab content (messages, web pages, about system pages). It should not be as complicated as setting prefs, userChrome.css, etc.
