Fox!Box will reach its End of Life with Firefox 57 (approximately end of 2017).

I decided to end the support and further development of Fox!Box.
The reasons are missing personal time and the announcement from Mozilla to end the support of XUL-based add-on with Firefox 57.

I would like to thank all users of Fox!Box, all who have written reviews and comments, all who gave feedbacks and all who requested further enhancements wishes.

A browser based alternative to Fox!Box is Cr!Box for Chromium based browsers.

Fox!Box by Leland Grunt (Version 1.3.0)
- A Mozilla Firefox extension for the AVM FRITZ!Box -

You are now only one click away from getting a new public ip-address.
Just click on "Reconnect FRITZ!Box" and your AVM FRITZ!Box will be reconnected to the internet.

The extension offers the following advantages:
- The current public ip-address will be displayed in the Firefox status bar/toolbar. You don't need to connect to the FRITZ!Box Web-Admin-Site or to open the FRITZ!DSL Software.
- One click and the FRITZ!Box will be terminate the current internet connection and then automatically reconnect.
- The current public ip-address can be copied to the clipboard.
- No additional software is required. If you don't like the extension, it is simple to uninstall it over the Firefox Add-on menu. No files will be left and clutter up your pc.
- "Fox!Box" is independent from a special operation system. You only need Mozilla Firefox.

This extension is for AVM FRITZ!Box owners only.

Note: If IPv6 Support of the FRITZ!Box is activated, the Firefox preference "network.dns.disableIPv6" must be set to true OR the value "fritz.box" must be added to the preference "network.dns.ipv4OnlyDomains".
