How to turn off Cloud sync?

This is useful and works very well and is a great replacement (with better features) of FAST DIAL. Many thanks !

So far so good. There are lots of options and at this moment have no time check all of them. Good job.
Update - Oh yes Juraj you had a very good idea developing this plugin. At first I thought, well, I'll give a try thinking I already have lots of bookmarks and this might be redundant. No it is not redundant at all. In fact it is much more powerful and easy to maintain and use than the native Bookmarks.
Thanks again.

New Update:
I dropped one star cause things are complicating. Maybe there are too many options or the whole thing is getting crowded and confused. Caveat emptor Juraj. A cute baby may be turn a monster.

It's all OK. Very good.
But with the last Firefox version (70.0.1) I lost all favorite site groups and in the GSD Option I didn't find the possibility to load the old saved setting.
So I downgraded to Firefox version 70.0.0 and all is now OK.
Bye

Excellent add-on, i like that is compatible with other discotninous add-ons and the free cloud sync feature. Highlly recommended.

Everything was perfect until I updated FF several days ago, and then Speed Dial started to crash FF and itself also. Now it dont even show my bookmarks and groups, and shows an error.

The Best speed dial.

I used to love this add-on until the moment I updated my Firefox to 70. Now it is a crap working full of problems. Are you trying to fix the issues?

Best speed dial we've ever tried. And we've tried them all. It does everything it promises and has no bugs as far as we can tell. It even allows animated gifs as speed dial thumbnails which we love. Fun stuff. It's the only one we use now. Very highly recommended.

I have set this as the New Tab page on my Android tablet, and it is exceptionally good with a wealth of settings for further customisation. I use groups in the same way that I use folders on the bookmarks toolbar of my Windows Desktop.

The only small point - which has been mentioned by another user, is that it could be even better if it were possible to rearrange the thumbnails within groups, but the developer's response suggests that this may not be possible. However, it is nonetheless still a superb extension.

Excellent add-on permettant l'organisation des marque-pages dans des onglets totalement paramétrables, leur synchronisation entre différentes machines et dans le cloud.
Impossible de s'en passer quand on l'a essayé.
