How to move tab bar down in Firefox 82?

[kingcobra-uk]

I decided to try out Firefox 82 on Linux as I gave up on it some years ago. I am getting very frustrated as I am unable to format the screen layout as I like it. The most important thing I require is to move the Tab bar from the silly place it is to just above the main display area under the bookmark bar but have been unable to do this so far. The current default location makes no sense to me at all. So unless I am able to move this easily and keep it where I want it in subsequent releases I will no doubt ditch it again.

Can anyone please explain to me why this is not possible or if it is how?

Have you heard about the optional userChrome.css file?

I haven't updated the file name, but the Firefox 74-80 file still works:

OK just found it does not look for userChrome by default so fixed that and it kind of works.

I have

Menu bar
Navigation bar
Bookmarks bar
Tab bar <<<< but the problem is this overlays the bookmarks bar!

removing the Bookmarks bar does not fix it, the Tab bar then overlays the Navigation bar!

Make sure in about:config you have these set to true:
extensions.webextensions.userScripts.enabled
toolkit.legacyUserProfileCustomizations.stylesheets

Overlaid... Are you sure you used the Firefox 74-80 file and not an older one? Newest is first on the list.

Both are true.

Yes the one dated July 17 2020 for Linux and Windows

However I have now removed the @namespace line by commenting it out and it works. I thought @namespace was required, or at least it used to be!

The UI is a mix of XUL and HTML. If you use one namespace, you lock out the other. You either need to use both namespaces, neither, or modify the code to work around using one of them. Using neither is definitely the simplest approach.
