Description

Air quality information from aqicn.org for your browser Real-time Air Quality Index for more than 80 countries in the World. Manifest v3 migration. Note This add-on is not official maintained. I forked it, then fixed bug and added more features. Changelog Fixes: Incorrect mapping between AQI values and pollution level labels — always showed "Hazardous". Window content not fully visible — the "wind" section was being clipped. Widget always displayed on Baidu homepage and overlapped content — fixed. Widget display restored on other search engine pages. Other changes: Fixed and added several translations. Completely removed moment.js. Completely removed jQuery. Completely removed es6-promise. Switched to using Canvas to draw the icon — removed static image. Migrated from synchronous localStorage to asynchronous browser.storage.local.
