Works perfectly on google chrome . Hay developer you should give instructions to press control . otherwise new users might don't know the real usage .
Great alternative of pesticide.......................... amazing tool for css.
Finally reduced my mannual effort, Awesome tool !!
Good alternative to Pesticide.
Developer mode is ON but, it does not work on my own website I'm working on but, it works on the live websites.
I got here looking for the Pesticide extension recommended by Angela Yu. I love this extension, it helped me A LOT to understand how CSS works, I felt like Neo when he could FINALLY SEE lol =P
la mejor
This is very helpful Indeed!
Doesn't work on the Mac. Installs but clicking the icon won't enable it, and no combination of keyboard shortcuts will make it work, either. If this extension is made only for Windows, the product description should say so.
Exactly what I'm looking for, great job - easy and simple :)
