Too many permissions.. Rated 1 out of 5 stars

You don't need all those for this add-on to work. Why would you need to access browser activity during navigation? And why browser history? Is Firefox going to turn into Google?

Group tiles? Rated 3 out of 5 stars

Could you add the option to add tiles that are groups with more tiles inside?

Where is the one-click screenshot feature Rated 3 out of 5 stars

Previous versions had a way for you to take a one click screenshot of the current webpage with a camera icon in your toolbar and it would assign it to the corresponding tile, making them look exactly as you wante, and fixing that issue of Firefox not assigning images to tilkes. Now the camera it is gone, and you have to do everything manually. Why you removed that awesome feature?

Firefox 57 Rocks with New Tab Tools Beta Rated 5 out of 5 stars

84.0b7 works well with Firefox 57 Beta. Of course there will be hiccups but am a happy camper. 57 . . . soooo fast.

Firefox updates keep killing add-ons Rated 5 out of 5 stars

Something is really wrong with Mozilla, they must be having some problems because there is no easy way to save a thumbnail homescreen. New Tab Tools was the best add-on for this, it worked perfect, but then after an update we all had to revert to old version 81 to import our settings. Now with Firefox 56 it does not work at all. Unfortunately adding all the bugs up with Firefox I will have to switch to Chrome and see if that wastes less of my time.

maybe just give up on Firefox instead of useful addons Rated 5 out of 5 stars

version 81, once I was able to find it and install it, worked perfectly, and now with FF 56 I am back to a useless page, but most of my addons are useless now anyway, so if there's a new tab tools for Chrome, I will be using that, buhbye Mozilla

My Most Favortie Add-on, I Need You Rated 5 out of 5 stars

Does not work with Firefox 56.0, nor does any previous version of this one work with it.
If at all possible you could make the New Tab Tools 81.0 work with Firefox 56.0 it would be amazing! Cause that's the only version that works for me without the annoying text in the url (tried the fixes they didn't work and also doesn't have the download, bookmarks, addons, ect. shortcuts at the bottom)

The very best - and it's gone :-( Rated 5 out of 5 stars

I came from Opera. This extension got me into Firefox: a screen with your most visited websites as tiles. Made the tiles manageable. Sadly, it's gone.

This Addon Should Be Part of FF. Rated 5 out of 5 stars

Even Qupzzila has proper Opera style New Tab. I will continue using this add-on in version 81 only one which works. Mozilla should add this add-on to main distribution not destroy it, IMHO.

Great addon - makes live easier Rated 5 out of 5 stars

This is a great addon since Firefox core tabs do not work at all for me. No way to adapt nor do control which tabs should be shown. This addon brings sense to the nonsense Firefox delivers out of the box. It is an addon I use all the time and makes Firefox worthwhile. It will be nice if this addon continues to support the current version for Firefox 53.0.2 and later. A fix will be appreciated.

Tiene algunos fallos en Firefox 56.0 x64 Rated 4 out of 5 stars

Un add-on genial que me encanta y me resulta muy práctico.
Espero que se convierta en Web-Extension para Firefox 57+.

Problemas que he encontrado actualmente:

1- Al iniciar Firefox me sale una página en blanco
2- Cuando abro una nueva pestaña me sale pero en la URL se muestra como "moz-extension://4881eb57-d80e-4cb4-962f-26c45eca63a6/newTab.xhtml"
3- Cuando le doy al botón de página de inicio no se muestra. He tenido que introducir manualmente el enlace anterior (moz-extension://" como página de inicio
4- Ya no puedo editar los diales haciendo click derecho del ratón ya que no salen las opciones. El menú desplegable es el estándar que sale en todas las páginas Web
5- Ya no existe la opción de actualizar la imagen del dial

Thank you! Rated 5 out of 5 stars

Much appreciation to you Geoff, for working out the issues. Without me having to do anything, it's now working since the very latest update. Few developers are as responsive to users. Many, many thanks!

84.0b2 ressource hogging, b1 fine Rated 5 out of 5 stars

As the title says, 84.0b2 is hogging ressources, when you open the new tab page Firefox CPU usage jumps to 30% and stays at that level constantly and RAM usage goes up, when you close it it goes back to normal. Repeat as often as you like. In 84.0b1 everything works as it should, no CPU usage and no heavier RAM usage.

I can also report that setting New Tab Tools as the browser startpage works again with the 84 version, it's the 83 version that doesn't.

PS
Please keep this in mind for the webextension: ghacks.net/2017/08/30/firefox-webextensions-may-identify-you-on-the-internet/

version 82 and 83 broken Rated 5 out of 5 stars

Like other reviewers have said, it no longer works in Firefox 54 and 55. I opened my Firefox 55 and told it to check for add-on updates, after it updated New Tab Tools it no longer works. Firefox says version 82.2 and 83 are no longer compatible with either versions 54 or 55.

I'm keeping my 32 bit version at Firefox 54 because I've found that some add-ons no longer work right with Firefox's new "improved" version 55. It seems Firefox is determined to destroy the one good thing about Firefox to improve it.

Update: Firefox acting screwy again. Appears that is the design for version 55. Add-ons seem to not work in versions lower than that if designed for it.

This addon is awesome Rated 5 out of 5 stars

People are really dumb when they review stuff. We should be able to review the reviewers. I'm about to try this addon again in release, but even if it's not good there, it's in active development and is looking fine in Nightly. This is a lot better than similar addons (Toby, for example) and especially Firefox's default start page.
