About this Add-on
Matching of hosts is done with either simple strings or regular expressions.

Example rules file:
# This is a comment.
# Delete headers using "" or ''.
# Indentation is allowed.
# Formatting with whitespace is allowed.
X-Forwarded-For = 100.101.102.103
User-Agent = Mozilla/3.0 (X11; I; AIX 2)
# Here's an incomplete rule, which will be ignored.
