Injects any hosted CSS file into a any webpage
Allows injection of any hosted CSS file into any webpage.
NEW (8/13/2012):
** Fixed deployment error that caused extension to break.
NEW (8/5/2012):
** Updated to work with newer versions of Chrome (using manifest version 2)
FEATURES:
** Specify any hosted CSS file to inject (local files must be hosted under http://localhost/~ - security restriction of Chrome)
** Single click toggles injection on/off
** Native JavaScript only - no included libraries or unnecessary code to slow you down
WHY DO I WANT THIS?:
** This is to aid in theming websites such as Wordpress or Tumblr. It's for those cases where you're developing a complex Stylesheet for a site template but you can't easily update the CSS file on the server.
** Using this plugin: you can work off a localhost hosted CSS file, just hit save, and see the results immediately. No more copying and pasting, or FTP-ing your CSS up to the server.
** Other CSS manipulation plugins only inject their own static css, or make you copy and paste into a box.
I'm sure there's some other use cases too. If you have any, let me know!

Not working at all. Waste of time.
As a simple tool for rapidly testing your CSS changes directly in the web browser, I really can't fault it.
Doesn't really work for me. I added a css file on a public github project, and the plugin correct injects a link tag for it when I click the button, but somehow it doesn't take at all, anywhere :/
Works great for using custom CSS on reddit. However having to force it to load manually every time I load a page is cumbersome.
Works great for me. It has improved my workflow when I don't have access to the files by FTP.

Cool! Love it
Doesn't work for me.
Never worked for me...
A creative creation.
Ideas are great, but will cause YouTube webpage malfunction (cannot click Like, Dislike, Share, About, etc.)
Wish it would allow different style sheets for different sites. For instance, I don't want to write one that moves the Facebook notifications to also be applied to Google pages.
Works like a charm! Thanks!
