Seems this issue was posted on Reddit earlier today. Someone with a response in the thread has a link to a solution that resides on GitHub. As always, check out the coding carefully before implementing. While I have a userChrome.css that I use for Firefox, I prefer having the default of the address bar below the tabs, so I can't help out here.

Actually, I wouldn’t call his an issue. More like a request that some Firefox users like.

/* This reorders toolbar to place tabs below other toolbars. Requires Firefox 133+ */

Thanks, that's exactly what I am looking for and other commenters verify it works with FF version 133. It's too bad that browser users have to resort to this. But I've found over the years the folks here on FR have the skills to help others so it's much appreciated.

Thanks again for the link. After saving my current userchrome file it was an easy install and everything seems to work o.k.
