Copy your IP to the clipboard from the omnibox. Type "copyip", press tab, space and then enter. Similar extensions I've seen require you to click a button in the toolbar, which consumes screen space. Note that it may take a few seconds for the IP to be copied.
My IP is faked in the video. The extension will give you your real IP.
Privacy note: In order to obtain your IP, this extension calls a web service hosted on AppEngine using CORS over HTTPS. The data transmitted is the same data the browser sends to any web server when loading a web page.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
