Firefox is highly customizable, and BottomUI make it ultimately. Rated 5 out of 5 stars

All I can do is offering 5 stars.
It'll be perfect, if the popup suggestion of awesomebar (address-bar) can pop upward, instead of poping downward currently, only one item can be read.

Thanks in advance.

Hello,

thanks for your review! Take a look at my successor add-on for Bottom UI with this issue fixed:
