Looks awesome and is easy to use.

Clean, simple, yet great customization without overdoing it, it's great. Nothing else like this exists on Firefox.

超棒!超好看!

Beautiful.

I couldn't figure out how to delete my previous review, so I'm leaving another one. I previously thought that Tabliss was causing Firefox to lose its startup preferences, but after lots of testing - it's NOT Tabliss. It's a weird FF issue. Tabliss is awesome! So, I'm definitely sticking with it!
Also, a side note, Joel at Tabliss was super fast to try and help me trouble shoot, even after we figured out that it's not the add-on that's causing the issue. So, kudos for awesome support and responsiveness.
You guys are awesome!

fine

It requires NO special permissions and does more than most other extensions. LOVE IT.

Love this add-on. It's beautiful and support is super responsive. Definitely recommended. It makes my mornings more soothing. :)

It's a nice way to start my day to open up tabs that look like this.

Nice wallpapers and nice UI.

Beautiful new tab page, very well put together

Goooood

Awesome app, better than Momentum (Chrome) btw. :D

Very simple, easy to use, not a lot of clutter. Just what I was looking for!

Just lovely. Suggestion: option that progressively darkens the background image based on the time of day. Would make the "Sleep well" message more coherent with an otherwise bright background.

A wonderful add-on to do for your tabs what GeekTool does for your desktop. It delivers an easy to use interface to embelish your new tabs and at the same time make them more useful.
At the moment of writing the extension has been stable and worked correctly on Firefox 54.
Absolutely recommended :)

EDIT: One proviso though.
If you happen to have your Firefox Preferences set to "Never Remember History", Tabliss WILL forget all your settings between sessions. If that is your behaviour then, for the moment at least, Tabliss will be not much more than a beautiful picture, the time and a basic greeting every time you open a new tab.

Very nice looking new tab page
