It happens out of the blue - I never know when it will start, but once it does it keeps doing it until I restart Firefox (25.0.1).
Everything will be fine, with NoScript functioning normally, then at some point I'll click the Options button in the yellow message bar, and instead of the menu popping up normally, it seems to be trying to appear under the the message bar, so I can only see a sliver of the menu. At least I can see that much, because if I couldn't, I wouldn't know anything was happening, and I'd think NoScript wasn't functioning at all. But if I hover over the NoScript icon, the menu pops up normally.
I noticed it only affects one window, so something must be corrupted in this window?
