Hi. This forum is intended for offering technical support assistance for Firefox users. We do not provide suggestions about add-ons, since they are developed and maintained by third party developers.

Sorry.

Add-ons support is over here: https://discourse.mozilla-community.org/c/add-ons

Yes, that sounds like many planted user reviews to "bump" the stars rating up. As far as those nonsensical user names, that is due to anonymous user names; no need to register and create an account any longer, which IMO devalues the ratings system making it a farce since that was changed.

So hard to find a 4k video downloader

Maybe you could find one here :

https://alternativeto.net/software/4k-video-downloader/?platform=firefox

(FlashGot has been blocked)

These come across as the best alternatives :

https://addons.mozilla.org/en-US/firefox/addon/video-downloadhelper/

and :

https://addons.mozilla.org/en-US/firefox/addon/savefromnet-helper/

Thanks for the great help @McCoy and @the-edmeister and apologies for posting to wrong forum.
