How to change the line spacing of the folder pane for Thunderbird 78.3.1 (64-bit) on RedHat Enterprise Linux 7.
I have been working with Thunderbird on Linux since ca. 20 years. A few days ago, after upgrading to version 78.3.1 (64-bit), I had for the first time the problem that the font size and spacing of the folder pane was so large that I could only see a small subset of my folders on my laptop screen. So I studied the online forums and found that one has to create a userChrome.css file in the right place and put a style sheet in it to control the font parameters. With the following entry
- folderTree > treechildren {
font-size: 11pt !important; font-family: Verdana !important;
}
I managed to decrease the font size, BUT this did not decrease the line spacing! So now the font is smaller but the lines in the folder page still are so widely spaced that too little is visible in the pane. I experimented with settings like
margin-top: 0px !important; margin-bottom: 0px !important; line-height: 1.0em !important; padding: -1px !important;
but none of them seem to have any effect.
What is the right parameter to change here and where is all this documented? (And why did this setting change in the first place after being perfectly fine for so many years?)

Try this:
#folderTree > treechildren::-moz-tree-row {
height: 19px !important;
min-height: 19px !important;
}
Double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Config. editor.

Using Thunderbird 78.7.1 (64bit), 19px from sfhowes' solution produced default spacing; 17px is what I liked.
