The minimize button is back! That's exactly what I was looking for. Thanks :)

Excellent ! I use all 3 addons, Close, Maximise & Minimise - they work perfectly when the main toolbar is permanently hidden (Feb 2024)

Works Perfectly

Doesn't work - cannot minimize, cannot find the icon and cannot uninstall it. Holy bullshit!

super Add-Ons!
Not sure what the below means??
"This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing."

Having Tree Style Tab combined with disabled tabs bar, those extensions are useless completely. There is no ability to place buttons in 'customize interface' mode.

doesn't appear in the overflow menu

what's the point of this addon ?

cannot set the button order, of yes please tell me how to do to install the close, monimize and restore and set the order

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.

perfect for kde users that want a windows-like experience where the titlebar and border are hidden

Thank you. It's getting harder and harder to get Firefox to work properly on a Linux distro.

Funciona en Manjaro.
