Works great. @media queries where the rule is marked as critical by Chrome but not the query itself don't get exported. Otherwise I would give it 5 stars. I feel sad for the dev cause of all the 1 star ratings which only result from people not able to operate the plugin.

Works perfectly: extracts the critical CSS as well as some other automatic online tools. You just need to look for a new tab in the Dev Tools and click the "Extract Critical CSS" button. Done, a file is downloaded instantly.

Doesn't work. There is no button to extract CSS, only for this page and options and etc. Also, extension button is grey, but the extension is enabled.

Does a good job of extracting the critical CSS, but the resulting CSS is malformed. It is easily repaired, and I have submitted a Support ticket. With this fixed, I would be very happy with this! Atg
