Nice addon! Rated 5 out of 5 stars
Great! Want it since optimoz tweak not update anymore.Good compatibility.One suggestion: how about adding floating sidebar support? That means floating sidebar like IE9's. Please think of it. Last words, I love this addon.This review is for a previous version of the add-on (0.1.1-signed).
I found an extension that makes the sidebar float and seems to work with this one: https://addons.mozilla.org/en-US/firefox/addon/sidebar-popup-panel/ Just click the float icon after you install it.
