Dont click the 'Reset Toolbar Layout' options, itll just deactivate the menu bar menus, greying them out and youll have to restart the browser to restore them.
Have only tried this on Palemoon 24 (new profile) but expect itll behave the same on Firefox 25, will check later and update if any different.
Also, when you untick 'Menu in Titlebar' and the browser windows maximized, and you have 'tabs on top' set, the tabs should be repositioned to sit next to the Firefox button in the top row, but this addon keeps tabs in the second row, as if the windows minimized.
So if you can live with tabs never being on the top row next to the Firefox button, and remember to stay away from the Reset Toolbar Layout options works fine, and like that when it shows the menu bar menus, will also keep the Firefox button menu showing, the normal way Firefox hides it when showing the menu bar's annoying, this way better
I don't know if it's because of a conflict with Compact Menu 2 or something else, but all this extension does for me is return most of my tool bars to their default settings and hide the menu bar. At no time did it actually put the menu on the titlebar.
Hey I really like this add-on, a lot. I might even love it.
I use MenuBar on Titlebar and now I can customize the Titlebar.
For one I use,
and then force the menubar over to the left with a large value for margin-right. If there's a better way, I'd like to do that, but perhaps you can add an option to hide the appmenu-button and move the menubar over to its position, or, just do it by default when a user selects MenuBar on Titlebar.
There's no need for the app button with the menubar showing.
Thanks sincerely for developing this.
When I uninstalled it, it removed all of the buttons from the toolbar and the add-on bar. Beware!
