The only replacement I could find for the lagacy Desktop add-on.
Missing features / Bug:
* I miss the possibility to create multiple speed-dials or sub-dials. Please consider adding this feature! Interestingly the "Add to Speed dial" option appears on the Speed dial itself, so in theory you could create sub dials.
* the speed-dial screenshots are always in a fixed grid and cannot be freely placed.
* The size of the browser window affects the aspect ratio of the screenshots causing various heights. Examples of this can be reproduced when you Add to Speeddial with an active side panel or when resizing the browser screen.
* Speed dial won't work in a second window you open in Firefox.
* Speed dial will show unexpected behaviour when you have a custom home screen URL set.

For the rest it seems OK. I hope it will proof to be as stable as Desktop, surviving several upgrades until FF stopped supporting legacy add-ons.

All of my Speed Dial icons disappeared !

Grotten schlecht!

Обновилось. Сохранены все настройки и закладки из предыдущей версии, ничего не утеряно. Наглядно, удобно, доступно.
Аддон для тех, кому "ехать, а не шашечки". Очень хорошо. Спасибо разработчику.

Абсолютно сырая пародия на настоящий Speed Dial. Одна жалкая страничка визуальных закладок с убогой настройкой и очень нестабильная.

Одно из лучших дополнений это FVD SPEED DIAL. Да что там говорить, целый ряд дополнений, ради которых я на Мозилле отсутствуют. Не будет их, придется уйти на Хром. А это дополнение для детей и написал его какой-то ученик

This used to be a perfect add-on -- your favorite bookmarks on a single page. Then they added feature after feature after feature, and now it won't work at all. Screw this.

Please bring the original speed dial in the new FF. I love this addon, but I can't use them now, because it is simply not convenient.
Or at least some of the features that you can.

This is a very shit speed dial. Where is the original!?

This was one of my must have addons. This version is horrid.

добавьте группы и резервное копирование и вы будете лучшими!!!

а так мне не удобно пользоваться имею больше 100 сайтов. с вами не удобно

I'm moving to Vivaldi now - this speed dial is the worst ever. Mozilla what were you thinking?

Absolute disaster, cannot move the dials, when adding they gets in without any order and even clone themselves.

*Doesn't allow to change dials' order
*Cannot be added to newtab ot home page
*Dials cannot be configured

Could be more developed in future, but for now I cannot use it, I didn't find it useful, sorry.

Stürzt beim verschieben von Dials gnadenlos ab und ist auch sonst eher unflexiebel.

I've been poking around for alternatives to SuperStart that work with Firefox 57, and chose this one because it seemed like the best match.

... That said, while I was aware grouping wasn't a feature, I didn't think simply rearranging sites would mean wiping them all out and re-adding them sequentially in the order I want them in.

While using it, it blipped out of existence, so I'm writing a bug report about that now.
