Me encanta me ha echo la vida mucho mas facil, aun que como todo se puede mejorar, esta entre mis favoritas, gracias chrispederick.com
It's really useful, but it crashes pretty much every day.
Amazing tool, recommended highly, maximum usefulness with minimum adware.
I've been using this extension for years, and honestly can't live without it in terms of web design. Its most valuable feature is the Edit CSS function, which allows you to actually see what you're doing and edit CSS in realtime. The Responsive Layouts and Window Resize are crucial for any self-respecting web designer in this mobile-site-driven age in which we now live. It's a free extension packing premium content. Thank you so much, Chris, for building this tool and distributing it for free. <3
INTERESSANTE, MAS SO PRA QUEM É DESENVOLVEDOR MESMO PRA SABER A IMPORTANCIA DA FERRAMENTE.
Forces notifications to be enabled in your browser. I don't care what this can do, no longer helpful until that changes.
great add on
where is "outline custom elements"?
Can't give it 5 stars... it took me HOURS to narrow down why FLASH was not allowed AT ALL! I wasn't able to visit chrome settings and adjust flash settings. Everything having to do with flash settings was grayed out and unable to change ANYTHING. Really upset that it would not let me know that this plugin was controlling flash on EVER page / site! And I still cant figure out how to have Web Developer enabled while having it NOT affect my flash settings!
Brilliant Extension with a vast range of tools from someone who 'gets it'. Well done Chris.
