Hail:
I use quite a bit of Extensions.
About enough to fil 2 rows in Firefox maximised on a 1920x1080 monitor.
Thus, about half the Extensions sit in the "Extension Puzzle Piece" icon where the ones sit that cannot be placed.
Now, we could fix this, if Firefox added the ability to let us create "Extension Storage Boxes" in this Extension Bar, to which we can assign an Icon based on our preference, wherein we could organise some our Extensions.
This way, we can click this "Extension Storage Box" Icon that opens a drop down menu holding the extensions in it which we placed in there.
Thoughts?
