The best download manager! Rated 5 out of 5 stars
I tried to download a video file of 265MB 5 times using the default download method built-in Firefox. Each time it would fail and interrupt the download after just 7% of the download progress. The estimated time shown was 45 minutes.
Then I installed DownThemAll and it immediately started the download with the highest possible speed. The time estimated for total download was around 25 minutes.Not even once was the download interrupted. It all worked great. EXCELLENT Add-on!
I fully recommend it.
