Great extension, and thanks for the super-fast response to the 0.4.9 hack.
The latest version adds ads (abrts.pro) to every page. I wonder if the tool has been highjacked, I don't believe the original author did this.
adding google analytics to the source of any visited website.

OK, 0.5 is clean :-) you can use it safely once again.
Very useful in a lot of situations, even for regular users. GUI could be updated to a more modern, fresher look.
it is very usefull
All in one tool that Google should buy and implement by default in the dev tools.
Awesome work,enabling and disabling features make more handy for development
