outstanding extension.it has worked well for me for about two years. The developer keeps it updated frequent enough as needed. I don't recall it ever not working even though YouTube constantly changes the way it operates.

good to use

The best video download extension. Every time YouTube tries to obscure download option, the developer is working really fast on a fix.

It is awesome and is really handy. I simply can't live without it.

The best add-on out there besides adblocker.

Great (probably the best) add-on for video & mp3. When YT changes its behavior, developer comes with a fix in a day or 2.

This is a must-have add-on if you use YouTube. Absolutely the best.

An excellent add-on for Firefox. The only one that I have found to get reliable downloads. It is constantly updated when YouTube code changes, so don't give up - follow the guidelines and upgrade to the Pro version with a donation of your choice.

A great little extension which is frequently updated. The developer puts a lot of work in keeping up with youtoube's changes, which makes it very usable. The "Pro" upgrade totally makes sense to support server costs he has for transcoding stuff.

The best video downloader plugin for Firefox.

Developer is constantly updating this plugin. Youtube breaks it, and within a day at most a fix is out. Best and most reliable way to download from Youtube I've ever used!
