Check Text (C-251550r961194_chk)

Type "about:preferences" in the browser address bar. Type "Applications" in the Find bar in the upper-right corner. Determine if any of the following file extensions are listed: HTA, JSE, JS, MOCHA, SHS, VBE, VBS, SCT, WSC, FDF, XFDF, LSL, LSO, LSS, IQY, RQY, DOS, BAT, PS, EPS, WCH, WCM, WB1, WB3, WCH, WCM, AD. If the entry exists and the "Action" is "Save File" or "Always Ask", this is not a finding. If an extension exists and the entry in the Action column is associated with an application that does/can execute the code, this is a finding.
