If your Firefox doesn't detect Companion APP

Delete Firefox and install firefox.tar.bz2 archive from official site, this would fix the issue

it's workingu very well - thank you guys

very good~

Despite the fact that it needs a companion app, it is the ONLY (such) extension that has NEVER failed me! It works..!

Really strong and powerful tool, thx :)

I've downloaded dozens of videos using this extension for Firefox on Linux, and it works almost flawlessly. The only glitch is that sometimes the download fails, but if you catch it early enough, you can restart it and it will continue from where it was.

Very nice for casual use. Works as advertised.

This version 7.6.0 works far more smooth than any others.
Esta versión, trabaja mucho mejor que las anteriores.

The MOST universal video downloader add-on for Firefox there out there. Been using it for FREE for years, but just sprang for the $28 registration, so now it can even convert videos without the watermark. (Free version converts, but puts a QR code in the upper left corner.) I only wish I had given them my money sooner. Polished and feature-rich, you quickly get a feel for which (of the dozens) links to download. So, it's quick to learn, and POWERFUL for power users like me. 5 FULL stars! :)

I would like to thank developers for this app, pity but i cant donate from russian card because of sanctions(

A very good video downloader. I am using it for years. Downloads almost anything. Easy to use.

I am using video-downloadhelper for more than 12 years. From my personal experience I can confidently opine that it is the best.
