Hi All,

I'm trying to modify various userChrome.css attributes of Tabs in Firefox 109.

However, code that worked in FF 88 is seemingly no longer working.

Is the below code outdated?

I would also like to change the appearance of #TabsToolbar from translucent to either a solid color or a background image. Is that possible? Right now, you can see icons from the desktop through the Tab bar, and there appears to be a strange curved, black overlay colorizing it. See attached screenshot.

Thanks for any input!

/* MISCELLANEOUS TAB ATTRIBUTES */

  1. TabsToolbar { /* tab bar */
 -moz-box-ordinal-group: 3 !important;
 padding-top: 0 !important;

 background-image: url("bkmr_back.gif");

You need to go to the site your using to create or edit your userChrome.css for support on your css edits as by default Firefox forum doesn't support programming css edits. Or go to a userChrome.css forum and post your question there for those doing css edits to review your edits so it works as what you want.

Hello Dropa,

I'm not sure I understand. For years, I've been getting help with CSS edits here on this forum.

What is the "site" I'm using to edit my userChrome.css?

Thanks.

Do you have other code in your userChrome.cssll code since I notice you have placed the Tab bar below the Navigation Toolbar ?
