Rated 4 out of 5 stars
Good work, It is almost perfect.
I just miss one little thing what this theme doesn't have and the previous one did have.
I made a screenshot from it.
I don't know if it's still possible to add/change this?
Sadly this was removed from Firefox 4+. However, this addon restores it, though I can't vouch for compatibility with PMR nor do I provide support for its use in PMR:
If you need this functionality without additional addons, you can hold the back/forward button, or right click them.
