Quick, handy, and compact with reliable results. A must for all web designers and developers. It compliments the development tools already available in your browser (this extension is also available in Firefox). Don't dismiss this extension because of it's dated appearance (UI); it's not pretty, but it's packed with functionality.
Cuando uso dreamweaver CS6 y cargo una vista previa de mi web, no funciona la regla, ni muchas de las opciones, en google chrome. En Firefox funciona perfectamente.
Display color picker не работает...Та и в целом- херь,а не тулс.Большой функционал,не всё тестил,но то что юзал-не работало.
Amazing. Thanks a ton for the efforts.
в "Chrome" не работают элементы!!!!!!
Memory usage is too many. Please be able to use any spec low PC.
even with the built in chrome tools, there are lots of features (forms, validation, cookies) you can't do without this extension. I think i've been using it on different browsers for ten years now. still the one and only.
Generally a good app but the handling of enable/disable javascript needs tweaking. I have several sites that I have specifically disabled javascript for, and the settings for the Web Developer tool override these settings - not good. So I have to remove this extension.
Very helpful
Wow this works perfect. It's awesome. The only thing is sometimes the disable options don't work.
