I've installed a Tree Style Tab add-on recenty. Now I want to hide horizontal tabs from the top.

I tired one solution from here: https://support.mozilla.org/pl/questions/1241745 and a solution from creator itself: https://github.com/piroor/treestyletab/wiki/Code-snippets-for-custom-style-rules#hide-horizontal-tabs-at-the-top-of-the-window-1349 (Hide horizontal tabs at the top of the window #1349, #1672, #2147) But to no avail. Can anyone help me with this?

More info about userChrome.css/userContent.css in case you are not familiar: *https://www.userchrome.org/what-is-userchrome-css.html

In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css in the chrome folder.
