Bug 1382840 - Making the nsRFPService::UpdatePref() to copy the string which been passed to PR_SetEnv(). r?ehsan The PR_SetEnv() needs the passing string been intentionally leaked. However, nsRFPService::UpdatePref() uses PR_SetEnv() without leaking the input string. This patch is going to fix this by using ToNewCString(). MozReview-Commit-ID: 97QQUk2sjM9
