A vulnerability affecting Firefox versions previous to 220.127.116.11 is caused by the "-chrome" parameter allowing remote attackers to run code with the current user's privileges. When exploited, the remote attacker can install malware, steal data, or simply corrupt the user's system.
The solution is to update to Firefox version 18.104.22.168. There is also a workaround: use the NoScript add-on with Firefox.
