Here are my karé icons for Web browser
15 icons in 32 px only
PNG and ICO included
They are primarily made for the Windows 7 Superbar, that's why they are of that size.
UPDATE 26/09/11 : 6 New icons + IE 9 updated (better colors)
Firefox - Safari alt - Chrome 11 - Opera - Internet Explorer 9
Nightly - Safari full - Chrome - Opera white - Internet Explorer 8
Aurora - Safari - Palemoon - Lunascape - Maxthon
