I have noticed a couple of problems with this package on Xorg with Plasma 6.4.5. that only affect firefox-esr-global and not other Firefox builds. Since there seems to be nowhere else to report them, I'll put them here in the hope that it somehow comes to the attention of whoever is responsible for the patch used. :)

The more important bug is that there are no window control (min max close) buttons when using the CSD titlebar. Obviously this renders the CSD titlebar unusable

The second bug is an annoying and distracting rapid flickering of the global menu bar that only happens in the menu of firefox-esr-globalmenu and not in any other applications. When the menu bar has focus and no menus are pulled down, or when moving the mouse over the global menu, the highlight flickers in an irritating way, the flickering also happens briefly if changing from one menu to the next and seems to cause larger graphical glitches as the menu pops into existence.

Works nicely, thanks. Does anyone know why firefox-globalmenu was removed from AUR?

Any chance of the global menu patch to be separate of the Firefox version so we can continue using the updated Firefox from official repos? There's already Firefox 131, this package is at 115

So glad to see Firefox with the KDE global menu back in the AUR. Thanks for this.
