Dodatek jest w miarę dobry ale wymaga dużej przebudowy jeśli ten dodatek ma funkcjonować normalnie to należy zrobić go inaczej to znaczy całkowicie go przebudować mianowicie pasek adresu powinien podczas korzystania z dodatku być pusty by nie było trzeba ciągle kasować adresu dodatku co zajmuję dużo czasu ikona dodatku powinna być mniejsza dodatek ten powinien się otwierać w nowych kartach bo w opcjach tego nie ma ustawienia powinny być na stronie dodatku w menu kontekstowym pod prawym klawiszem myszy a nie na wierzchu jak dotychczas powinna być możliwość zrobienia kopii zapasowej i jej przywrócenia oraz opcja wybierania ilości wierszy i kolumn tworzenia nowych kart dla kolejnych skrótów witryn także dużo mu brakuj do dobrej aplikacji szkoda ze mój poprzedni speed dial jet już nieaktualizowany był zdecydowanie lepszy na stronie dodatku powinny się wyświetlać opcje dodatku a nie opcje przeglądarki co zupełnie utrudnia korzystanie z niego powinna być też możliwość importowania pliku HTML jeśli ktoś ma skróty z poprzedniego dodatku ...

podsumowując dodatek do dużej przebudowy słaby

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 !

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.

The first thing that was noticed was the background image.
There doesn't seem to be any clean or solid colored images.
There also wasn't a tab of speed dial pages. If I wanted to have 27 cells they would have to be on one page or tab where as I would desire three pages or tabs with 9 larger cells on them. Each one of those pages would then contain 9 larger images that would have refreshed pages that were viewable.

Compared to original speed dial this one has almost zero customization and enforced background images.

You can only customize the amount of dials, their colors, their spacing and their url, but not their aspect ratio, size, title, background image. The background image of the table are not automatically changed and a configuration box is affixed above the dialers even out of configuration mode. There is no option to exclude scrollbars, or to increase or decrease margins between the dials and the browser border. The imosibility of group tabs bothers, but is within the concept of being a clean addon, which can not be said of the other characteristics.
