Renewed Tab is pretty great, the pictures are beautiful, the settings are very clear, and its quite customizable. The only reason its not a 5 star is because it slows down if you increase the widget board past normal on "work mode" ( at least on my computer) and you can't make the picture change on command, more frequently, or move. But over all, Renewed Tab is quite a good extension. If I could give it 4.5 I would.

it asked me to leave a review, so here i am :D
extension is more than decent, there are some quirks that need to be polished, but overall, i'm satisfied.

I'm using this extension for zen and satisfied with the quality.
Can you add Japanese language support?

Very very nice, unfortunately there's no option to change the background depending on system theme preference, so I get flashbanged with a light background when my pc changes everything to dark at night. If this is ever implemented it's an easy 5 stars.

Very good might steal your data but lets be honest everyone has your data. 4/5

Great, however I would love to be able to change the favicon in the tab. (Like nightab)

Search bar is not responsive.

can't change background (15 minute wait)
otherwise, very nice; simple easy chill
nice pictures, clock

This extension's appearance and the experience during using is fantastic. But the initial loading time is horrible and blocking the main website loading thread. This must be improved before I give this extension a fire-star rating.

Much better than Firefox's default new tab page, but the weather applet is bugged (can't set location) and the webpage shortcuts are bugged (too many shortcuts makes it error out). Otherwise, it's nice not having your retinas burned out every time you open a new tab.
