The big downside is that it doesn't work when the page didn't load (connection timeout). For example when reddit is blocked in my country. A big downgrade from Flagfox. What was possible with Flagfox in 2 clicks, Is impossible with this addon. Even though the function exist, it isn't available when you actually need it.

「URL バー」内の右サイドに、
ウェブサイトのサーバー位置の「国旗」が表示され、
アイコン上をマウスホバーすれば、ツールチップに「Whois および Geo 情報」が表示されます。
そのうえ、アイコンをクリックすることで、「https://www.tcpiputils.com/」からの詳細な情報が得られます。
必須アイテムです。

Awesome add-on

Hey, very nice addon.

One question though, does it handles all data (Like URL etc) locally Or send them to remote servers?

very good and fast

日本国旗就是一个红色的小点

默认的国旗图标太小了，都看不清楚，希望把图标弄大点

Very good addon. Being able to see the origin of a server and being able to look up the IP address is great added functionality to the Firefox Browser.
