what is so hard about asking for the destination?
I used to use this a lot more, and now it's my last-resort video downloader. Why? Because it keeps dumping my downloads in the "downloads" folder! It never used to do this! What is so hard about asking me where I want the download to go? (Especially if it's a long video and I don't have room for it on my hard drive)
And for the record, I've got Firefox set to "always ask" where to put downloads.
The issue started after youtube changed the way downloads are delivered, this has already been fixed and an update should be submitted to mozilla for approval in next 2-3 days.
