Esta bueno, gracias
Really awesome, I have seen ever....
nice tooll for evry one
Great addon. Thanks for sharing! :) It would be nice if I could save the "Web Developer" settings changes in the cloud.
One problem. The popup window on clicking the extension icon is not big enough to display the tab after "tools" tab.
I've used Chris Pederick's Web Developer tools for years. They're invaluable if you're debugging some JavaScript, or examining page structure. Recently I've been working on REST API development and the tools work excellently here. Many, many thanks.
Great!!
