I cannot live without this extension. After the major FF upgrade, my SpeedDial of Joseph Del Rio was incompatible. My search turned up Juraj's Group Speed Dial.

I was delighted and after a day's playing around with it, I just had to go Pro - I could recover the old dials by importing from Del Rio's Speed Dial and now I am soooo happy - everything works like clockwork
.
By the way, if you also use both FF and Chrome, this is a massive blessing to have your speed dials synchronized.
Thank you Juraj! I am one great fan of yours!

Beau.
