Seen couple of negative comments & 1-star rating for the extension. The developer was maintaining this wonderful extension for last couple of years. The developer of this extension asks that you help support its continued development by making a small contribution. At that time how many of you, those are giving poor ratings, bothered to donate the developer for this extension? It’s Mozilla & not the developer who had ruined the browser. If you are not happy with this extension, then move on to some other browser or older version of FF (ESR). I uninstalled FF 57 & went back to ESR only for this extension. Can’t use any other browser & without this extension, it’s impossible to use FF. On ESR, old version 5.1.7 is working perfectly fine.
Giorgio Maone, please ignore all the negative comments in review section. Will it be possible for you to maintain old version 5.1.7 for ESR till June 2018? Thank you for the support of this wonderful extension till today.
