I want to highlight elements when I click on inspect button then click on specific elements, then the whole page will be grey and blocked and the selected element will be highlighted.
There's an amazing example on mozilla 6 plugin that inspect elements without using firebug, I wonder to be able to make like it or even use the plugin.
Also google plus send feedback use sth like this, can somebody guide me how can I make it give me plugin that I can use..
Thanks in advance :)
