Speed Dial for Firefox 57!!!! Rated 5 out of 5 stars

WONDERING ABOUT FIREFOX 57.... I've been using this add-on for years and it has been the Best of the Speed Dials I have used... I don't believe in putting all my marbles in on basket so I have looked at alternatives.... I will no longer have any reason to remain with Firefox as my primary browser as the next best is Speed Dial2 in Chrome......
