not applicable to all sites and videos.

very good add on

doesn't seem to work

It's ok, I guess. My regular video downloader is not yet able to make it to the new Firefox, and this seemed like it would work in the meantime. It has a few things I would like to change, but only to be like my old one. It does the job well enough for now.

It works really well sometimes and then it doesn't download at all. and works on fewer sites than my previous add-on.

I installed this extension and my anti-malware software (Malwarebytes) flagged it as a potentially unwanted program (PUP). Since false positives are (for me) a very rare occurence with Malwarebytes, I'd rather not take any chance and just got rid of the extension.

By the way, Video DownloadHelper finally issued a version compatible with Firefox Quantum...

ne fonctionne pas sur youtube

I can't download videos from youtube anymore, yesterday I could ,but today it's kaput! Please fix it, the add on was excellent.
