J'utilise cette extension sous Chrome et Firefox. Je dois dire que son interface est plus agréable sur Firefox, mais son utilité reste la même quelque soit le navigateur : époustouflant.
its helper extension i use it to develop my blog
I literally could not function without this extension. It increased my productivity by several factors and allows me to figure out issues much faster. I also had an issue with it and the developer was able to help me on his website's forums in a timely manner.
