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'?

То, что искал, простой и удобный интерфейс. Спасибо разработчику!

Really love this addon. One thing I was going to make a comment about was that my icon to add a tile to the new tab page had disappeared, but it seems that it reappeared with this newest update. The only suggestion I have to make would be to allow for some method to backup/restore. Lots of addons have this, and it comes in real handy if you need to make a new profile, refresh your profile, or set up another installation. Otherwise it's great and I recommend it to people all the time.

Wie kann ich "neuer-tab-tools" als Startseite einrichten, für Firefox57+!?
Habe eben eine Lösung gefunden: Zieht die "neuer-tab-tools"-Seite in die Lesezeichenbar und macht einen Rechtsklick auf das entstandene Lesezeichen und geht auf "Eigenschaften". Dort wird eine Adresse angezeigt, die ihr kopiert und in den Einstellungen (allgemeine Einstellungen für Firefox) für die Startseite einfügt! fertig!

Thanks. It worked like Jewel. You don't know how much you have helped me. Thanks a million man.
