Hi I find horizontal lines between messages a big help. I've updated to TB 115.0 and the lines have disappeared. I referred to the past set-up method. I've checked that the chrome.css file still exists in the correct directory and have checked toolkit.legacyUserProfileCustomizations.stylesheets is set to true. I've tried switching to false, close down, open and back to true, close down, open, without success. Can anyone please advise how to reinstate this feature? Thanks

was recently forced to upgrade to winblows 11.. in the previous version of Thunderbird, 102.2 64 bit, I could follow these instructions to background colors in the various panes .

https://support.mozilla.org/en-US/questions/1389364

Now with version 115.0, I am having issues getting it to work.

the CSS file I am using is

1. threadTree > treechildren {

 font-size: 16pt !important;
 font-family: Times !important;
 background-color: lightgrey !important;
 color: navy !important;

}

1. folderTree > treechildren {

 font-size: 16pt !important;
 font-family: Times !important;
 background-color: lightgrey !important;
 color: navy !important;

} after I follow the instructions, carefully, nothing happens. see screenshot attached...

I have 2 questions:

1 - what am i doing wrong? 2 - In the attached screenshot, how can I get rid of that toolbar in green on the left?

Does anyone know how to change the folderpane colours in 115. I use a userChrome.css, which no longer works in 115, as I beleive the commands have changed.

This is what I use currently, but have no idea what changed need to be made to make it work in 115. Any help would be appreciated.

Since Thunderbird changed the menu bar is not any more above the email bar. It is with Bestand, Bewerken, Beeld enz.

How can I get it back at the top??

It is far less easy now.

I wanted to ask for help but on the Dutch site I could not find a button for help. Only at he English site.

But I am Dutch.

Hope that I can get the Menu bar on top again like in Firefox..

Please help and change it back.

Kind regards

Re: userchrome.css It appears only part of my userchrome file affects customization in latest release (115). Is there any information on use of, or changes needed, to continue customizations, e.g. mail folders font weight, message pane grid lines, mail folder pane background color, thickness of pane splitters, etc.?? Everything worked in 102.x...

I currently use:

  <profile>\chrome\userChrome.css 

to make various buttons stand out for some elderly users that I support. For example:

1. button-archive:hover {

  border: 2px dashed black !important;

}

1. button-archive,
2. hdrArchiveButton {

  background-image: none !important;
  background-color: #66ff66 !important; 

}

I can't figure out how to do this with Supernova (115+). Thanks.
