Firebug 1.13a8 fixes 11 issues
Firebug 1.13a8 is compatible with Firefox 26-29
We introduced one nifty enhancement that allows displaying original CSS color values (issue 5507). There is a new option Colors As Authored that allows to display CSS color values as they were defined. This makes it easier to compare the styles interpreted by the browser with the ones inside the original CSS source file. While this new option is now the default, you still have the possibility to switch to hexadecimal, RGB or HSL formatting.
You can use our online test case to check out this new feature. Note that you need Firefox 29+ to use this feature.
Please post feedback in the newsgroup.
