Hell bless, this extension needs some more fixing.
Im wondering why the reload button isn't working.
Furthermore, why are the buttons (settings button, reload button, and even the date/time toolbar) so light-colored and small? They are quite hard to find, mind you, esp when the background is bright in color.
And also, the entire tab really is just... a wallpaper. It is EXACTLY like the screenshots posted btw. You can look closer at the shots to determine it for yourself.
The changing picture thingy isn't working for me, but that might be a Me Problem.
Overall, I aint using this extension.

It's great. I can't find an option for a new image every new tab. I found an option for a new photo every hour, which is good, but, I can't find the new photo every new tab option. Thank you anyways!

Can't upload own image. Major flaw

You can't change the wallpaper. It also removes everything else from a new tab, like the search bar.

its very nice, thanks

sadly is indeed a wallpaper. as it is pasted over everything in your new tab. all i want is to change the bacckground

Works well, would be better if it just added background to stock homepage instead of replacing it but as it is it's fine

This uses online wallpapers, not your own custom wallpaper.

It seems it doesn't work on the Mobile version of Firefox. Could you check and maybe add in the FAQs a possible solution?

Not perfect but I can't find anything better. Thank you!
