Tranquility Reader is a Firefox add-on that makes reading easier by removing unnecessary elements from the web page. It is similar to using the Reader View mode in Firefox but it also has other features too like changing the color scheme, using a dark mode, saving pages to read for later, highlighting notes and so on.
Download and install the add-on from here.
After it is installed, it will be available next to the address bar.
To enable the Tranquility! mode, simply click on the add-on once the web page is loaded.

A note window will pop-up, enter the notes in it and click Submit.

Different display modes like Dark mode, Matrix mode and others are available.
You can also change the color scheme, the font type, text size, the highlight color as well as the reading width and other preferences.
To save the web pages offline, use the Export option. To load previously saved ones, select Import.
