The plugin is showing "Hazardous" instead of "Good" when "Good" is displayed on the website.

An application that you can rely on, especially if you are in China. THANKS to the developers!

This app is very good in getting the real-time pollution information for your neighborhood. I would be happy to give it a five star except that it gives the wrong label. For example, today, my neighborhood API is 63. According to U.S. EPA, the right category should be "Moderate" ( However, the app categorizes it as "Hazardous". Can someone look into this and correct this obvious non-sense?

First time i added the extension 4 months ago it worked, had my city Grass Valley, CA in it, then last week I noticed the index was really high and saw it was showing sacramento. tried to add gras valley again, but it never showed up in the list. went to the website and searched for grass valley and there it is. The extension does not do all the locations for some reason. not useful to me if my city is not going to be shown. Loved it up until it stopped displaying my city.

Hope multi-city (simultaneously displayed) functionality can be added in the future

First time I added the extension, it works. When I typed in the city I wanted, it shows 5 options (different regions within the city). Looked great! However, when I tried to change the city, no matter what I typed in the search bar, after hitting "ENTER" or the search icon, the search bar would return to its previous state showing: "Enter the name of a city". No results or any other messages are shown. Deleted it. Wanted to review it, and then realize I need to have the extension added in... Show more

The pop-up haven't been loading for the last few months. It woked in the past
