So my question isn't how to change the size of all the tabs which seems to be asked a lot. My issue is that occasionally Chrome will decide to make the font size smaller of tabs that have really long titles. Best described via screenshot:
As you can see the tab furthest right has much smaller text.
Also two other notes: I am using Windows 7 and Chrome version is 24.0.1312.57 (Official Build 178923) m.
