I hate Firefox just for its displaying the alt attribute for the img elements. Well indeed I'd prefer Internet Explorer Developer Tools (I mean in Internet Explorer 9 or 10 rather than the IE 8 I am using), to the built-in developer tools in Firefox...
And now we know, at least Internet Explorer 6 (the lowest IE version I have tested; IE 10 does too) has been supporting the CSS "word-break" property (even better than Google Chrome when dealing with word-break:break-all;
), which Firefox 15 finally supports.
Now Firefox 16 also supports unprefixed transforms, gradients, transitions, and animations, etc. (Damn, not box-sizing yet!!!!!) Life is never so fun as it is now!!!!!
