I recently updated FireFox to it's new version and added add-ons. Usually, when an add-on gets added, it shows immediately on the top left on the toolbar. (in videos and articles). However it doesn't display on mine. I did some research and found another method: customize toolbar -> drag the add-on to the toolbar. That didn't work either because no add-ons displays when i enter customize toolbar. Instead, there's an add-ons icon to drag. Dragging it on the toolbar and clicking on it doesn't do anything. I also read that if the toolbar is full there would be a + icon and when i click on it add-ons shows up. (my toolbar is actually empty and i don't have a + icon). So yeah, i'm left with no solutions. Appreciate some help and suggestions.
