why the F was the min max button missing? thanks for bringing it back : D

nice extension. Can you do give option to change its color to white, which will be great for dark mode

Works Perfectly

Does what it says , but needs an 'Are You Sure?' step.

The button is meaningless, it is on any window. We really need an addon that, instead of closing the window, firefox throws it down (minimizes), so that the "close" button works just like "minimize". Old addons (Minimize to tray and "minimize when close, close tab (s) on Esc (Delete)") do not work! Please make such an addon.

gg, thx

This is a must have if you're running Firefox borderless on Kubuntu or any other Linux distro. Makes the window as slick as in windows 10.

Amazing! It's super helpful when it comes to Firefox Quantum on Linux

It is very useful under KDE and other window managers systems. Obviously not in Windows or MacOS.

Good for closing the whole window option, but somehow a clae tab button addon would be great...

Works great! A must for those of us who hide the titlebar or customize nav / bookmark / tab bar order, allowing us to put the close button wherever we want! The authors' other button addons work great as well!

Feature Request: allow us to pick the button color so we can match our theme colors! =)

Great!

Works as stated. One little niggle is that it doesn't have the "Are you sure you want to close this window" dialog which sis a little annoying
