Firefox was acting weird for a few days, so I refreshed it. Now my extensions in the toolbar have vanished, and I can't figure out how to pin them back. I read online instructions and saw a couple of videos, and they basically suggest that I click on "customize toolbar", then drag the addons onto the bar. Except that in my screen, my addons don't show up in the selections, so I can't drag them up. The addons are installed, and the weird thing is that I have ONE addon on the toolbar, but if I unpin it, it also doesn't show up in the possible selections (I had to press undo to keep it). Help?
