Lately (since Firefox 8 and 9) I have noticed that while I tab the left Ctrl button it will enlarge the text the way Ctrl++ would. It is incredibly annoying and I have to compensate with Ctrl+0.
Now it doesn't happen everytime I hit Ctrl. I can't predict it.
I've looked in about:config to see if I can see anything that stuck out. I didn't.
Any ideas where I could disable the ability to enlarge text or why this is happening?
