why this plugin request permission of ''read and modify my bookmarks'' ?

This is a great add-on that compliments Firefox well. Thank you to Geoff Lankow for developing it. To those who are having trouble with the "Capture Thumbnail" feature I had a couple of sites that weren't displaying thumbnails automatically. This is the procedure I followed to capture the thumbnails.

1. Open the new tab page and left click a tile without a thumbnail.
2. Go back to the new tab page, delete the tile and close the new tab page.
3. Go back to the tab displaying the page and apply the "Capture Thumbnail" function.
4. On the same page as (3) above apply the "Pin to the New Tab page" function.
5. Open the new tab page and the tile should be there with its thumbnail.

There may be other variants of this procedure that also work.

Regards to all.

good

How to force a thumbnail update? it's stuck on an error even though the site is available.
Sometimes slots just aren't cleared - clicking on the 'x' is ignored.
Finicky UI, instead of just right clicking the thumbnails you have to use arrows.

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

Exactly what I needed to avoid the new quantum-whatever headache.

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

Nice add-on. Looks good and works well. Only 3 stars because I cant seem to be able to sync tabs across multiple devices.

Its a great add-on that works effectively. For those who are tired seeing the default new tab page of firefox, you must try this add-on. It has lots of customization. I just hope that the developers can add a feature that makes the new tab tools the default page when the browser starts.

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'?

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!

"IT HAS EXPORT FUNCTION! OPEN ADDON FROM ADDONS PAGE AND YOU SEE EXPORT/IMPORT OPTION, FFS."

Calm down, my version has no export/import function. Neither on main settings nor at the Add-on page.
NewTabTools 84.1 FF 56

BTW, Firefox has an inbuilt screenshot app.

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