I really like the ability to personalize. There are many who are moving from "Speed ​​Dial" by Josep del Rio because it has the ability to use the Ctrl with more than a single digit. For people like me, who have 20 groups and more than 200 pages, I find it easy to access them by memorizing the number and only typing it with the Ctrl. I feel that otherwise this AdsOn is excellent, but I still occupy modzilla 57.0 because I do not have that facility in any other AdOns. And to be honest, this is the one I like the most and the one I see the most in the future. I would love to have that option, since it is really very comfortable and makes the navigation very efficient and precise, more when I use 4x4 groups and only my first page has 12 very frequent pages. To incorporate a similar or better solution, not only would it put the 5 stars, but it would change my rating in SpeedDial to promote the use of its AdOn, since that function to many even made them change to WaterFox or in my case, not update to Quantum.
