After one week of pause I'm quickly pushing another edition of my weekly link tipps before my birthday tomorrow.

Testing tools and suites

• Modernizr 2.6.2 is out and has some new things: position sticky, CSS's @supports, input[form], bugfixes and improvements

• Firefox 15 developer tools update with amazing new features: make screenshots of selected elements, view media queries inside the not-resized browser window!

New things

• We now have a position: sticky; option in CSS
