The FlashGot option for the Firefox right button may not be available because the account name used to log on to the operating system is in Chinese (you can see it in the "Start-> Logoff"). FlashGot does not support Chinese user names. To use FlashGot normally, change the temporary directory in the flashgot "option-> advanced" to the English path, and then restart Firefox. In addition, users of the use of Flashget, please note that some anti-virus software (such as MacFee) will be Flashget folder Jccatch.dll as an ad file deleted. Once the Jccatch.dll is deleted, FlashGot cannot detect the FlashGet.
