Rated 5 out of 5 stars

I found that minimize addon bar incompatible with some addon like lori(after disable, restart and enable, it disappeared) and DNS Flusher(don show button on addon bar)

Flush DNS: https://addons.mozilla.org/en-us/firefox/addon/dns-flusher/
lori: https://addons.mozilla.org/en-us/firefox/addon/lori-life-of-request-info/
