Amazing!
thanks
Evet yıllardır kullanılan eklentiler chrome içinde geliyor artık tavsiye edilir sadece biraz kurcalayın yeter.
在FireFox下就开始用这工具了，非常不错。
Web developper is the best SEO Extension ever !
Heads-up: Sites for which you may have blocked JavaScript will be allowed again! (chrome://settings/contentExceptions#javascript) Adding http://* and https://* Allowed is necessary for the commands to work. The array of commands are wonderful but I'd like to suggest some interface improvements: - (Chrome) Add a search engine. Example: I go up to the omnibox and type `wd [Tab] respon|`... and it auto-suggests the "View Response Headers" commands. - (Any platform) An even better alternative, a Ubiquity-style input field. (See Ubiquity for Firefox, gleeBox for Chrome of SublimeText's Command Pallette). Invoke it and start typing to invoke commands. - (Any platform) Make commands templates and string them together (See Template extension for Chrome). Example: I'm writing a post and want to craft a link to a named anchor inside an article I'm reading, and have the link's text be some title property or some bit of that site's metadata. I go to the Web Developmer search box and type - (Chrome) Integrate it in Chrome Dev Tools instead of the top bar. If possible have it load only when Dev Tools is open, so it doesn't take up RAM. - (Any platform) Allow JavaScript bookmarklets in Tools, not just URL templates. (See Template extension) Bugs (Chrome 34 on Windows 7): - Color picker doesn't work and crashed - The extension's pop-up menu gets scrollbars on when I click the icon, (until I change to a different tab of commands)
5 stars extension. Nothing else to say :)
Thnx. Really cool!
Edit CSS, View CSS does't work from ages and because of this plugin sucks
Lost without this tool.
