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.

Hello Geoff,
I am Robert aka StarBaseONE2. Way back 2017 I was a long-time user of Geoff's New Tab Tools & I submitted the following review then...
"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."

Now the year is 2026. And I am still a faithful everyday user of Mr Geoff's New Tab Tools extension. While I can't say I can prove from documentation that this is the longest continuous time that I have ever employed any extension; I can readily affirm such from looking at this years calendar and from memory. For that to be true this is arguably the handiest piece of software known to mankind.... OKAY to this man anyway. I wouldn't operate my browser without it STILL here '26! That sir is a notable accomplishment.

Install it folks, take the required time to see it properly set up (meaning the way you like it best) and in 5 years remember what this old man once said and send a thank you note to Mr Geoff for such a superior notion and creative accomplishment. Thank you Geoff I do love your work!

I finished my review back in '17 with the last paragraph below that I still would love to see come to pass if Mr Geoff has the time to look at an old success story, that he has left to rest on its laurels and age gracefully...

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