Why do text sizes vary so much on MacBook Air?
I have a new MacBook AIr (11", Mid-2013) and the text sizes displayed while browsing the web change from site to site. The text size is either proportional to the rest of the display (menu bar, browser tabs, etc.) or quite huge. This appears to be a Firefox problem, because I don't see the same behavior on the same sites in Safari. I use Firefox because of add-ons like Noscript and AdBlock Plus, great security tools that are not available for Safari. The problem also seems to occur more often in Google apps (such as Gmail).
This behavior does not appear on by MacBook Pro.
