It doesn't seem to make any difference. A particular download is still 50kb/s and keeps failing, no auto-resume (same as using no addons).

Even slower than the native FF downloader

I've been using this for over 3 years and now it has gotten to the point where it's buggy. It no longer keep track of things that I've paused. Can't even resume any paused one, I can see the PART file on my drive but it won't pick it up again to resume. It has been like this for over a year now... I'm not convinced that InBasic is ever going to fix this. It's time for me to move on.

Yes

It's fine

Totally useless. Could not work out how to use it

doesn't do shit

Does not auto-resume broken downloads.

way beyond my expectations
