Use this if you need a persistent highlighter. Great job, Marius!

Me ha gustado mucho, tiene su propio modo lector que pude poner en modo oscuro. Me encanta que puedo elegir entre diferentes colores de subrayado. Me ha resultado muy útil :)

Amazingly convenient tool! No bugs encountered till now.

very useful app, that easy to use like in adobe pdf. just GREAT

非常地好用，感谢制作者，许愿中国区云端数据稳定

Just fantastic! All you need in one place. Highlight, save articles, comment, transfer them. Never lose a thought, a quote or a reference again.
Thanks a million Marius!

I love the amount of colors there are to pick from when highlighting! A lot of these extensions only have 4 colors or just don't work. Thank you for making this! <3

fulfills all expectations, please add group highlights by color and search in the notes

I wish I had discovered this highlighter tool years ago—so easy to use, so smooth in syncing across devices.

5 stars. Addon is great. Though, a bit too much advertising, ad inserts, and premium offers.

So amazingly simple and easy to use. Thank you!

很好，非常棒的插件，太喜歡使用它，希望大家也多多愛用..

gooooood

This is one of the more useful add-ons that I have used. Like any add-on, it takes up some memory, and on occasion it has slowed down my internet response time on some applications. I simply disable the feature during those times, but it is a valuable tool in highlighting text for the articles and studies that I like to read.
