Several suggestions for further function improvement:
1. Specific setting of colors/background for for group dials.
2. Auto-refresh for thumbnails with interval settings.
3. Browser resolution setting for thumbnails generation.

That's some of important functions included in old add-ons.

Very useful extension! Visually great for fast net surfing, web-site templates with small image of them are very helpful!

I was using Fast Dial for years in Firefox. I was so disappointed when Firefox Quantum (v57) decided to delete it. I was using Fast Dial as my home/start page in Firefox. After investigating, I found your Group Speed Dial is the BEST replacement for Fast Dial. With all of your options and settings, I was able to design my Group Speed Dial just like I had my Fast Dial. Thanks for your hard work and also for a fine product. I will be sending a donation!

Thank you , you have saved my day , i was on firefox 56 with the old speed dial by josef , and yours is far better on 57 , the import option was very usefull !

Сохранение и быстрый доступ в важным закладкам.

Merci au développeur qui nous permet de récupérer nos paramètres stockés dans l'appli "Speed dial" de Josep del Rio !
Keep going !

Thank you very much :)

Speed Dial от Josep del Rio FF v57 не работает
в папке Data\profile\SDBackups\ сохраните последний дата сохранение залкадок с расширением 20171115.speeddial скопируйте другое место , и обновил аналог этот Group Speed Dial зашел в настройки import dials from "Speed Dial от Josep del Rio" ниже выберите файл и ждите import Finish!
все нормально спасибо...

A very worthy replacement for Josep del Rio's (apparently no longer supported) Speed Dial addon.

very nice add-on really. Just one question, is it possible to show only title of each dial and suppress all thumbnails? I sometimes don't want to see those thumbnails at all. Thanks for help in advance.

I really like this add-on to FireFox. I have grouped a few hundred bookmarks into a a few pages and they look pretty and are very useful. I use the Pro version which has upload and download buttons to save the dials on the cloud. The dials on the two computers I have can be synchronized at will. Having all the dials in the cloud makes local backups redundant. Besides they are accessible everywhere.

perfect

Единственная достаточно полноценная замена настоящему Speed Dial, который с Firefox 57 не совместим.
Главное, спокойно восстановил все диалы из сохранённой копии SD Backups, а их около 500 в 23 группах.
Дополнение от марта 2020 года.
Несколько месяцев назад заработало нормально расширение Group Speed Dial в хромообразных браузерах, причём бэкап из Firefox полностью воспроизвёлся SlimJet и в Comodo Dragon, что весьма порадовало

Very helpful developer who responds quickly to help requests and is quick to fix issues with their extension. Also, very good add-on that's quickly becoming more fully-featured, and is (imo) the best speed dial extension for Firefox 57+.

Best and comprehensive speed dial, simple intuitive operation. It would be good to work on language mutations. I recommend everyone

Good and fast.Thank you!

I used to use Speed Dial by Josep del Rio, it is still the best in my mind but there is none like that in Chrome.
Then I tried FVD. It is good but so lagging, slow down my browser and have few limitation of dials (have to pay for more).

Now, I tried Group Speed Dial and it works very well. I can also have the same dials in Chrome.

Thank you.

However the pro options is very interesting.

More suggestion:
- Have some options to customize the size of screen shot in case that I have many many dials in a single group, the dials will be so small and screen shot looks bad. If I can capture the screenshot for example: 800x600 and automatically resize to match the dial size will be very good.
- In Speed Dial have schedule to generate new screen shot for example every hour, day.

This is the best speed dial add-on that's out there now supporting all versions of Firefox!!! And the developer is really a helpful dude!

Import from Speed Dial [FVD] worked flawlessly. Took a few mins to figure out thumbnail sizing (scaling/ratio stuff), but once figured out, I could set things to resemble what I've been used to for years.
Coming from SD [FVD] I still wish the addon would allow scrolling without forcing users to obey max amount of dials per one group screen without affecting size. But I'm satisfied with this addon nevertheless.
Thanks for your work Juraj!

On slow computers with white color theme firstly appears black screen, then appears white background. This blinking is annoying.
