I mean it even has custom CSS, what more can I ask for?
Edit: on second thought, it should have more of the features of Firefox's default New Tab so you don't have to sacrifice those to move onto Tabliss (frequently visited sites, Pocket blogs)

Such a nice extension. The feature to have a new wallpaper for each new tab makes it exciting to open the tabs plus the catalogue of images is great. Tbh one of my favorite extensions

Really great add-on. Simple, but makes a big and nice impact for my day to day use. Love being able to set my own images on my computer as a background, and the extensive customisability including ability to change positions of things. 5 stars.

very good add-on and very smooth :) can now finally have hatsune miku as a background image!!

Grate, but can you add "bing image of the day" form bing.com as background souce?

Simple, efficient and well done. Thanks

Better than firefox's default new tab.
