The version 0.4.9 had Virus, but was resolved and cleaned at he 0.5. Amazing Tool Again!
This extension began serving me popup ads today, nearly gave me a heart attack thinking a client's site became infected! UPDATE: author fixed immediately. awesome extension
i used for years, but there is aggressive ads in last version! never more!
First, thanks to your work! I was a bit confused as I saw these loaded JS etc. and also noticed some (sex) adverstisement on i.e. Google.com Thank you clarifying here, that you account was hacked. I had to update the extension by myself. Is there no emmergency option at the Chrome Web Store, which tells all browsers to update imediatelly?
Seems that in the last updated this extension contains a malware that shows an script alert and add their own add system

Quick response to compromised v0.4.9 release
Great tool to assist in web development!
Version 0.5 confirmed clean. Version 4.9 was hacked.
Started injecting scripts and causing redirects to adverts on link clicks
