Best Speed/Fast-Dial addon, and I guess I tried 'em all over time.

This one relies on non-commercial, non-proprietary tech and is transparent because you can handle the bookmarks in the standard Firefox bookmarks view.

Thumbnail refresh is rather slow, but I this might be a limitation of webextensions (it has to load the whole page in a new tab first).

Let's hope this one keeps being maintained - I'd like a "dark theme" with plain dark background.

Need a quick, large and wide Up Button. I hope the author will default to the following flexible style:

#pages {
display: flex !important;
flex-direction: wrap;
flex-wrap: wrap;
}
#pages > * {
padding: 3px 15px;
}
#upbutton {
flex-basis: 100%;
order: 2;
text-align: center;
font-size: 1.5em;
padding-top: 15px;
background: rgba(0, 0, 0, 0.15);
}
.delimiter,
.customdelimiter {
display: none !important;
}

/* Other */
body {
background: #a7a7a7!important;
}
.imgcontainer {
border-radius: 0px 0px 10px 10px;
}
.container table tr td {
border-radius: 10px 10px 10px 10px;
}
div[type="remove"] {
border-radius: 0px 10px 0px 0px;
}

Just try it, there's a surprise.

Incredibly stupid addon. I couldn't make it work - it prompts to add new page, I do, but nothing happens. Don't waste you time for this.

Yay. Missed SD from Opera, same functionality plus better having button than kludgey bm add in Opera. Happy you use bookmarks' thumbs as I use NoScript, so into privacy and no tracking. Plus SPEED which many add-ons forget.

I tried to use it but today I decided to remove it.
Win7 64bit, firefox 64bit too
First could not move the tree of folders and bookmarks from the old fast dial for a long time. For some reason, the usual copy/paste did not work, only part of it transferred. Yes, I know that the tree was big, but fast dial was working with him without problem. Finally the tree was moved and it looks like everything worked, but sometimes when I was opening a new tab BSD in no hurry to show me the bookmarks and I was forced to close firefox and start again. But I was almost satisfied and I spent a lot of time updating images for tabs and folders. Today came an update of the firefox and I see only few folders and two links on the main page .... where are all???. my patience was over ((((
Old fast dail, it was perfect and comfortable!!!

Одна из немногих, настолько гибкая, и без лишних встроенных механизмов синхронизации, синхронизирует вкладки сам firefox, а приложение лишь отображает красиво.

I cant get it to work....I want my old Fast Dial back!!!

Easy to configure and always in sync.
It would be nice to have the possibility to update ALL thumbnails automatically, not just all on one page.

This is the one and only webextension that allows me to navigate the standard Firefox bookmarks visually without any fuss. Thanks a lot!
However, for every new opened tab it is faster to load and more usefull to me the default Firefox "activity stream" tab. It would be great if there was an option to disable it in the new tabs but still be able to access to it with the already included toolbar button.

Excellent, simple speed dial. can integrate with native bookmark.
NO NEED cookie & history permmision, 3rd party account for multi device sync!!

Is seems that Firefox 58 makes the extension unusable. The browser freezes when I open a new tab.

Problem solved! It was the background image. Thanks!

Does exactly what you want it to do.
Too bad it's ugly and clunky.

I would like the speed dial to show up when I press the home button too. Other than that the extension is useful although it's not very stylish but it does the job. I would also request a way to drag existing pages around to order them. Just make it look a bit more like Opera's speed dial, that's my suggestion but overall well done!

Utilissima e a differenza di altre registra i dial tra i bookmark permettendo la sincronizzazione tra diversi PC.
Very useful and unlike other records the dials between bookmarks allowing synchronization between different PCs

How do I import my backup from SpeedDial.html or CurrentSettings.speeddial?

poor interface~ i will come back to ff 55
