Bastante organizado.

Marvelous tool for stipping the junk blocking clear reading of website screens.

Nice App

Tranquility greatly helps to reduce visual and mental clutter and helps to store or share articles without including unneeded elements and links. I find it very useful indeed.
Recently the developer kindly added the URL at the top of the page, which eliminates another tedious step in sharing or saving articles with a source reference. To the developer: a sincere THANK YOU!
A respectful suggestion: Many Tranquility-processed web pages omit the original TITLE. Could the title be included in all cases, please? If it's not included I have to manually insert it while saving or sending the Tranquility-processed article, which wastes a lot of time.

Works, but why would I use it over Firefox' inbuilt Reader Mode?

I love this extension. It does exactly what's needed for creating a distraction free, aesthetic reading environment. It also doesn't try to do too much. Bravo!
