There should be more extensions like this. Ace.

Decent and privacy respecting.

Search engine defaults to Google, and the "Cool stuff" section comes with links to GMail and Google Drive. There's settings to change that, but there are a lot of settings, and so it feels a bit daunting to configure when search and shortcuts work fine in the default FF new tab page.

THE BEST. Just perfect!
To set it also as new WINDOW homepage, make sure it is the only tab opened, then go to Settings->Home and set "Homepage and new windows" to "Custom URLs.." and hit "Use Current Pages"

Hello! This addon is seem to be very cool! But why did I give you 4 stars, why not 5? The answer is simple: it doesn't compatible with Custom Scrollbars extension. If you visit their reviews page, you will see that I arleady told the dev and they did answered me. Would be cool, if nightTab supportthe Custom Scrollabrs extension. The issue is that scrollabr on homepage and new tabs are grey and you can't change it even with CS extension. Please, fix the issue.

Супер визуальные закладки!

Множество удобных настроек, без рекламы и очень стильно!
Спасибо разработчикам!

I've tried many newtab extensions, but this one is simply the best. No worries about ads or spyware and the customization options are insane. The screenshots barely hint at all the capabilities. After the initial setup, invest some time to read through all the available tweaks. You'll be amazed. This should definitely be a recommended extension by Firefox.

Wow, what a cool addition! From animation to color. This is what I needed! Customization is just great!!!!
