A Firefox extension that adds the following items to about:config context menu:

1. "MozillaZine Reference" -- will link to the MozillaZine Knowledge Base page for the selected preference

2. "MozillaZine Group Reference" -- if the preference does not have a page("MozillaZine Reference"), try this. It links to another Knowledge Base page showing preferences for the preference's group name, but in much less detail. For example, there is no page for bidi.numeral, but this link will show preferences (including bidi.numeral) beginning with bidi.

3. "Web Search" -- performs a Google search on the preference name

4. "MozillaZine Results To Panel" -- web pages returned by 1. and 2. can be displayed in a panel instead of a new tab

A private version (see the JSON branch) adds another item, and will not be offered through AMO

5. "JSON pretty-print" -- will pretty-print a JSON encoded preference, opening it in a new tab.
