Hi Team, When I am parsing the Gecko engine based browsers then I am getting empty engine version instead of the version which is available in the UA string. Example UA string: Mozilla/5.0 (Macintosh; Intel Mac OS X; U; en; rv:1.8.0) Gecko/20060728 Firefox/1.5.0 Opera 9.27 As mentioned in the UA string the gecko version is 20060728, but still it shows empty version. Please check. Thanks
