As you can see in the image below, the 3 tabs are in 3 different levels of contrast.(the first one is a regular tab.. the second one is with hover/mouseover and the last is the current tab.) http://img520.imageshack.us/my.php?image=ffox2b2qz7.png The current tab is the most legible/clear one and the only time I tend to look at the tabs is when I'm looking to switch to another tab and it takes too much effort to read the text in those tabs. Compare readability with the same fonts used in the bookmarks/menu toolbars. Even in the new theme concept mockups the contrast of the fonts is not affected and they look perfectly legible. http://wiki.mozilla.org/Image:Fx2-new-theme-concept-tabs.png IMO normal vs bold is good enough to differentiate between the current tab and others. maybe a leave the other tabs in the regular background color and make the current one white/bright. but there's no need to make the fonts duller. Reproducible: Always There seems to be a windows bug report that is almost similiar but the tabs don't look as bad/unreadable on the screenshots I see there as they do on my desktop. https://bugzilla.mozilla.org/show_bug.cgi?id=350690
I think this was probably fixed - 2 branche is now unmaintained - so closing.
