Good
Brilliant Extension with a vast range of tools from someone who 'gets it'. Well done Chris. As for your open and honest transparency its hard not to continue to trust the application. At least I know that if something is wrong ill get the truth and instant support in resolving the problem. (Hats_Off) Apologies for not agreeing with those of you slating the developer for the breach. Im in support of you all receiving a well deserved a full refund! Chris, you can keep mine! :)
As a long-time web developer, I have used this tool in multiple browsers, on multiple platforms, for more years than I like to admit to anymore. I have exactly one complaint. I wish that the default sizes used in the responsive layouts were also used to pre-populate the resize window options. Aside from that, I love it and plan to continue using this tool for as I continue to drive a keyboard for a living, and as long as this tool remains available!

thanks for this Great work.
Malware?
Super helpful dev extension, especially love the responsive layouts view!
Thanks for the extension take down and your quick code fix after the exploit, Chris. Keep up the good work.
