Update after 6 months: I am still very happy with this add-on. Downloads most of the ones I try with relative ease.

The feature that allows me to choose the directory and name prior to download makes it nice.

It still does not seem to do YouTube without humongous water marks which makes it unusable but it is fine. I have not used the new update but I assume the history will take care of the errors that makes me forget what I was attempting.

Orig: I am really happy I found this extension. It works very well. I have been using it for one month.

I read lots of reviews of this add-on about safety and concerns. So far I have not encounter them and it is coming to one month of use.

There were some concerns about companion app in the reviews so I also did a search. I did not find anything that concerned me and so far no problems.

I like the fact that I can rename the files before they are downloaded and like the convenience of being able to use long file names. One has to be careful about using characters that are not allowed by windows.

One thing that can be improved is when there is an error, I would like to know the file that was not successfully downloaded. This may be my inexperience/setup who knows. It was showing the information but it stopped it one day. As I mentioned, it can be due to my improper setup.

Overall, this is great!
