Review for DownThemAll! by Fire_Mage
Rated 3 out of 5 stars
Very useful although I don't think it downloads faster than normal.
Causes a short (few seconds) freeze before downloading large files which affects the web browser as well.
Sometimes large downloads cut out (estimated 5% of the time).
Does not have an official scheduler which is quite inconvenient.
Still, I use it for around 50% of my downloads.
