A simple extension that displays an estimated time to read the active tab
With so much content out there, it's often useful to know in advance how long reading a page is going to take you.
The estimate is unintrusive and displayed in the extension action area.
Reading speed can be customized in the options and the label color can be changed to match your browser theme.
The extension is open source: https://github.com/d-bucur/reading-time-extension
