Have been using mog multi-row_tabs_below_content.css (and also mog fake_status_bar_w_bookmarksbar.css) with Firefox ESR 128.

Now updating to Firefox ESR 140, and to my surprise, almost all the CSS continues to work. The only issue is that the menu bar has disappeared, and won't come back.

There was something to do with menu bar in multi-row_tabs_below_content.css, so I replaced that file with the latest versions of the two new replacement files, multi-row_tabs.css and tabs_below_content_v2.css. This did indeed restore the menu bar, but it broke tab bar scrolling (and a few other incidentals).

Do I need some intermediate version of those files? OR, if I go back to the original configuration, is there some way to restore the menu bar?
