There should be more extensions like this. Ace.

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"

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!!!!

Looks great!
