After the bug with a recent update I was able to restore my data from a backup just fine, after re-installing the add-on. So here's is my five star review back. :) Still the best start page out there.

Thank you for this. Would be great if there was a way to open it on startup.

Fantastic addon with tons of customization. Leagues better than the other "new tab" addons out there

Finally! A functional and customizable new tab for Firefox! Thank you, this is amazing.

I finally found the perfect speed dial extension and I gladly replaced Speed Dial 2 with nightTab as the latter is just superb- free, cross browser and open source, highly customizable (it offers an abundance of options) slick interface (many themes available), fluently working export/import, no privacy concerns and on top of that the developer is very helpful and responsive. In conclusion- nightTab is an exquisite extension which offers enough options to please the pickiest of users.

Been using nightTab for a little while now. It's incredibly easy to configure and customize, and I love having my bookmarks off of the toolbar to reclaim even a little screen real estate. Pinning the nightTab tab so it's there every time I open the browser is great. Dev is super responsive on GitHub, and it took less than a week to get a suggestion implemented into the extension. I had self-hosted my own startpage for a while, but I keep coming back to this for now.

It's great! But there seems to be a problem in data recovery. When I import the JSON file exported by another device, it shows that this is not a JSON file. I had to manually add my bookmark again

Open source, works great, looks nice, and fully customizable. Everything that I look for in an extension is here. Kudos zombieFox

Oh my god thank you. Thank you. Thank you. Why is it so hard for so many to understand basic, non-obtrusive design? This is simple, provides so much functionality and configurability without endless attempts at stealing my attention and assaulting me with stupid shit.

I wish the whole Internet would be like this.

Much can not be said, everything is already in previous reports. Indeed, this is the BEST OFFLINE start page that has been searched for so long. Of course I have one that is more like practical and not so pretty. Simple settings, nice looks, ready-made themes. Looks awesome on a 4K display. Keep it up !!!! There is a question to the developer: I couldn't import the exported data on another computer, the JSON file structure looks wrong.

This is the New Tab launcher I always wanted !
It's simple, beautiful, powerful, customizable, and very light on resources.
Wonderful work, I Love it !

Amazing new tab! The best looking I've ever seen :)
