Good but...
- I can't change the "Preview" manually (eg; I don't want to have a RGPD or cookie information in this preview)
- Why some history appear on the menu ?!? no button for disable that?
- When I drag some element I need to reorganize approxymately all
- Need each time to go on "configuration menu" for add new tiles...
- When I have only 3/4 colunm, the height is so crazy why I can't change the height or create button for auto height?
- Backup config?!? if I want to use this config in another browser?
- Why startxxl in "default search engine" when I use duckduckgo and I can't change...

And I think that's all, the rest is good, contact me if you need some other information
I edit this post if needed

back to being very good, thank you:)

On the floor of the setup menu screen. Impossible to remove.

Es gelingt mir bisher nicht Speeddial als Startbildschirm zuinstallieren damit ich auf dem Tablet genauso wie auf dem PC die Bookmarks auswählen und aufrufen kann. Auch nicht wenn ich in den Einstellungen/Startbildschirm den Link von Speeddial reinkopiere.

Endlich gibt es einen vernünftigen Ersatz für das alte Speed Dial.

how use firefox bookmarks?

It's a really good replacement for the outdated old "Speed Dial" add-on. Nice backgrounds.
