A Firefox add-on to browse the Internet of Things

How to integrate the Copper sources into Firefox:

1. Get the sources from Github: clone git://github.com/mkovatsc/Copper.git
2. Add a text file named [email protected] to your extension directory of your profile:

• Windows: C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxxxx.default\extensions\
• Linux: ~/.mozilla/firefox/xxxxxxxx.default/extensions/
• MacOS: ~/Library/Application Support/Firefox/Profiles/xxxxxxxx.default/extensions/

3. Write the path to the Copper sources (i.e., the directory that contains install.rdf and chrome.manifest) with (back)slash at the end to the file (e.g., D:\Projects\Git\Copper\).
4. Since Firefox 43 you need to allow unsigned add-ons by opening about:config and setting xpinstall.signatures.required to false.
5. Restart Firefox.
6. Optionally use about:config with the filter "copper" to clean up old configurations.

Copper should show up in the add-ons list. You can now enter CoAP URIs (e.g., coap://californium.eclipse.org/) into the address bar and will have a user interface to interact with the CoAP resources on a server. The detailed log output is available through the rectangular button on the top right, next to the preferences button.
