Unfortunately, this add-on is just another trick to get you to install third-party software (an "additional helping program") of unknown provenance, whose security threat is unknown. I tried it with a Yahoo video only to find it would not work unless I added their special program.

First of all installation: It requires a "helper program" to be downloaded and installed to your PC separately.
Then the plugin downloads the video, but spends your CPU cycles to add an annoying QR code for the developer to the downloaded video, adding BOTH delay AND annoyance to the download process.
If I wanted a QR code added to the video that I want to save, then I would ask for it.
Useless and annoying. Don't bother installing this
- 来自 Sunday_Scour，1 天前评分 5 / 5The 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! :)
- 来自 Flachzange，3 天前评分 1 / 5Memory Leak recently (20GB Ram usage even when closing everything), sporadic high CPU usage for no reason, sometimes 30% on an modern 8-core CPU, again even when closing all tabs besides an empty tab (the extension wasnt used or opened at all in either of those situations). Firefox performance analyzer clearly showed it was coming from this extension.
Besides that, the user interface is clunky and doesnt work correctly if the extension icon is moved into the dropdown menu.
