Typing the numerals 1, 2, 9, or 0 into a web form such as when creating a new note in Evernote web, Firefox jumps to another tab or changes the font size.
In certain web forms (e.g. when typing a new note in Evernote Web), I can't type the numerals 1, 2, 6, 9, or 0. Typing "1" or "2" jumps me to another open tab. Typing "9" or "0" changes the font size. Typing "6" doesn't do anything that I can easily see.
I'm using OS X 10.9.5 and Firefox 38.0.1. I think this problem first appeared with Firefox 37, though I'm not completely sure.

When I restart in Safe Mode, the problem seems to go away. However, after systematically disabling each of my extensions, it didn't seem to be one of them that was at fault. Perhaps it's a plugin issue?
