Few days ago i installed Speed DIAL FVD on all my machines together with Firefox 62.XX/Quantum. Been using the ESR edition in the past few months. Had no problems at all threfore i have to say i'm quite satisfied with this extension so far. Threfore: five stars !
This is the best speed dial extension I've use on Firefox and Chrome... The only problem for me is that when I start firefox, FVD doesn't open, but it does when I click on new tab... Maybe i'm doing something wrong.
