Been using the Desktop add-on for years, but that has stopped working with Nightly and I had to move on since there were no updates.
I suggest you add the options to remove the box-shadow and background-fill. And also the option to hide the locked-toggle, maybe even the Settings button, as well.

For those that want to do it, in the meantime, you can do it through the following CSS code (look up how to use userContent.css):

@-moz-document url-prefix("moz-extension://f80a360e-8248-493f-9d3f-717b8bccc341/newTab.xhtml") {

/*Hide box-shadow and background-fill*/
.newtab-thumbnail {
box-shadow: none !important;
background-color: transparent !important;
}

/*Hide lock toggle*/
#locked-toggle {
display: none !important;
}
}

Thank you for the add-on. Keep it up.

Thanks! about:newtab back to what I was used to and now customizable.

Exzellent, genau das - und mehr - was ich gesucht habe!

Excellent. Now I got all my favorite websites on a 5x5 grid when I open new tab.

Спасибо разработчикам.

good

Einfache Bedienung, sauber implementiert, macht was es soll - super! :)

How can I add newtab tools as firefox startpage in new Firefox 57?
Works fine since years! Best add-on!

Fait exactement ce que je recherchais.
Permettre de personnalisé l'affichage de la "newtab" page, et choisir le nombre de lignes, de colonnes, les sites affichés, les fond de couleur, les textes, les aperçus personnalisés... Et d'afficher ou non les historiques etc...
Bref, c'est un must have pour avoir le controle maximal et surtout ne pas le confondre avec un autres qui a un nom très proche mais ne fait absolument rien de tout ca.

Love it so far. Tho I would like to see some additional options if possible, like option to remove title fully and to have ability to set thumbnail background to transparent, because while using custom thumbnails without background the grey box is visible, which is a bit annoying. Thank you for this awesome add-on!

简洁好用

It finally works with the ridiculous changes in Firefox and it's worth a donation to the author, who never gave up. I had to add it to bookmarks and then open it from there to get it set as one of my three home pages, and there are times when all I get is blank page, so then I just click on another tab and it will load, then click on home and it will (usually) load again properly.

My most beloved addition to my browser is this New Tabs Tools addon. Recent changes in Firefox rendered it inoperable, but doing a little research at github set me straight, and following instructions there, I got it going again! I am having to reset all my tiles back to how I like them, but Geoff likely kept me from seeking another browser with me being able to get this running again. I've gotten old and set in my ways I guess, because when I like something; I sure resist any change! LOL

Thanks Geoff Lankow for the best addon that I regularly use.

If I may a suggestion for you sir. I need another page of tiles...
Any way of setting up multiple pages of tiles for 'power users'?
