Sorry for reopening an old thread but I cannot get userChrome.css to do anything in BetterBird on Windows 11. The code section shown below does work for Thunderbird. Here is my userChrome.css
What am I doing wrong?
/*
C:\Users\MYNAME\AppData\Roaming\Thunderbird\Profiles\r2v9k1zw.default\chrome\userChrome.css
*/
/*THE FOLLOWING CSS INFO CAME FROM THE THUNDERBIRD ARTICLE AT:
https://support.mozilla.org/en-US/questions/1418171
AND IT WORKS IN THUNDERBIRD V115.12.2
*/
/*Background color for sort group headings TRW */
#threadTree tbody [data-properties~="dummy"]:not(:hover, .selected) {
background-color:#DED072 !important;
font-weight:bold !important;
}
/*This puts an underline under each email row TRW */
table[is="tree-view-table"] {
border-collapse: collapse !important;
}
tr[is="thread-row"], tr[is="thread-card"] .subject {
border-bottom: 1px solid #ddd !important;
}
/*THE FOLLOWING CSS ATTEMPTS TO MAKE CHANGES IN BETTERBIRD EMAIL
(FOR EXAMPLE TO SET USERNAME TO GREEN AND UNDERLINE ALL THREADS).
EVEN WITH THE toolkit.legacyUserProfileCustomizations.stylesheets SET TO TRUE,
IT DOES NOT APPEAR TO DO ANYTHING IN V115.

.name {

border-bottom: 1px solid black !important;
