Rated 5 out of 5 stars

I see some new version had been released with "downloadhelper integration" - sounds like disappointing and dangerous, considering what crap addon this "downloadhelper" is. So i better stay with 1.5.6.12 version- working fine and great, thanks author

This review is for a previous version of the add-on (1.5.6.13). 

It just means that if you happen to have *manually and intentionally* installed also Downloadhelper (i.e. you're an user of both the extensions), the latter is given the ability to send downloads directly to FlashGot. Nothing harmful here ;)
