Limit IPv4 addresses to dotted-decimal form (as per RFC3986)
RFC3986 specifies that host IPv4 addresses must be in dotted-decimal format (xxx.xxx.xxx.xxx) in a URI.
However, on certain platforms (Unices) Firefox also allows alternative formats: octal, base 256, single long int… There is a longstanding ticket to change this behavior, as alternate IP representations nowadays only serve for malicious address obfuscation or filters bypassing.
The Tor browser should stick to the RFC in order to prevent such abuses and present a uniform behavior across platforms.
