Cannot Add Firefox Add-ons to Toolbar or Overflow

I guess, you need to right-click the image and select view image.

Yep, that was my problem sorry.

Give feedback to Firefox folks to fix it.

Yeah, sometimes, changing the source code, and recompiling is easier than explaining the problem.
But trying to explain to them seems the only way.
Thanks again, if I find a solution, I will post it here.

I don't understand what the left arrow is referencing. Got the other two arrows.

Left arrow is refering to the area in blue sphere( blue circlish area)

...If you remove it from there, you cannot add it again.

Did you click Remove Extension by accident instead of Remove from Toolbar...,

or, is the add-on in question disabled?

I don't see anything like that on your picture.

Maybe you just have too damn many add-ons!!!

Geez! Your browser must be sluggish as hell!!!
