I came from FVD, installed Group Dial, and sorry to say, am going back to FVD.
There is on page 2 here a review "by vee, 21 days ago"
that claims that FVD charges for more dials - totally untrue.
FVD has never charged for anything pertaining to the dials.
I am NOT an employee of theirs or in any other way associated with them,
other than being a normal consumer with their extension installed.

They are around a long time. Yes, they maybe still a little bit slower, but also
serving up a lot more customizing options. Just far more mature. That's all.
Am sure that within a year or so Group Dial will also have good changes to show.
Right now it's more Beta than anything. This is not a critique just a statement.
I am around a long time online [since 1993] and have seen many come and go.

Group Dial is definitely one that will remain.
For now I will continue to use FVD, that now is also faster after their re-write for FF 57.
The only slower aspect is the rebuilding of thumbnails. Everything else
[cloud storage etc.] it has everything and more .

Just wanted to set the record straight that they never charged anyone for anything
and have no intentions to do so. They have a business with some software etc.
where they have a regular shopping cart. But the Speed Dial is provided 100% for free
ever since their inception many years ago.

I would pay [I I do for a Pro since I have close to 3000 dials and want the benefit
of customer service solutions fast if needed]. I have enjoyed their speed dials
extension for free since many years, and they too have to make a living.
There is nothing wrong with that. I'd consider the same benefit if I would use
Group Dial as my primary bookmarking.

I will come back from time to time and see hopefully progress and maturing. :)
