Love the bright bookmark colours (Bright Green) can see them in a flash,

But, The Tab Text (Light grey/purple?) can hardly see it, especially if many tabs are open, Maybe a bright light blue/cyan?

The Address bar, yes, brighter i can read it but i think a bright orange would be better again your eyes see & recognise these brighter colours (Especially against plain and dull/dark backgrounds) much quicker.

Anyway thanks, I hope to hear of this design coming out for us that work, and need to see/read a lot of info all at once and quick without squinting or being distracted by the pinball flashing colours and picture backgrounds, Cheers John -G-
