An absolut must have if the number of installed extensions grows. It should be a FF feature. Works great.
But the Sort by function is useless. It doesn't work for me, and it should have options like install date, days enabled, days disabled, last update... and a quick option for reverse order.
I also suggest:
- To enable Ctrl+F to put the keyboard focus on the search field in the add-ons/extensions window/tab.
- To add an option for showing addons of the same developer as the one currently selected in the Show menu: Addons by -selected extension authorname-
- To add a setting in the Filter Extensions options button to select the items present in the Show menu, there`s a lot, and I only use a few.
