excellent Rated 5 out of 5 stars

first add-on with a bug yet still is so beneficial it's a must have. ability to change default fonts, sizes for folders, menus & toolbars, globally, great news for large screen monitors where the font is tiny. makes every day use much nicer. the bug? every time I change a font setting I get a pop up error. TypeError: window.opener.TabsInTitlebar is undefined. I click ok and it goes away. no biggy and who cares since it doesn't seem to bother anything. using WinXP
