As an extension this hits almost all of the points. It's very lightweight (only 200kb size compared to FVD for example which is 7.1MB in size), looks very clean and offers an adjustable background image rotation.

There are only two reasons why I can't give it 5 stars. First, when the description mentioned widget plugins I had hoped the functionality would be somewhat extendable which is sadly not the case. The existing widgets lack a lot of customization and the option to add custom CSS relieves only part of my need. Second, the description mentioned Speed Dial functionality, but in practice that's only a very limited link list. The option to assign an icon and title is great, but for someone who uses their new tab page like a visual bookmarks folder, it's not nearly good enough.

In summary, I love how clean and professional the new tab page looks and Tabliss does have some nice features, but it doesn't hit all the spots for someone who uses it to open links in a Speed Dial manner.
