i dont think you should be reading manga with out this extension. one problem i notice sometimes it chops the panel in half. for example half the body with be on the other side panel if your using the flp book option

nice and handy

Il pre-caricamento del capitolo successivo mi ha letteralmente cambiato la vita, specie quando leggo su siti lentissimi come Mangadex. Estensione stracomoda e pratica, consigliatissima

Very handy features such as showing when a series has been updated, keeping track of what you chapter you just read - this addon makes it very convenient reading on-going series. Highly recommended.

Very useful.

Have used it since i was teenager. love it.

an excellent free way to browse manga, definitely some issues with lag but that's probably more due to the sites they pull the manga from
