Pro- Able 2 preview/Watch video before you DL
Con- It collects and store all videos you come across while surfing the web.

This add on is great, I've only ran into a few sites it wasn't able to download from. I would say the only downside is that it will collect every flash video you come across as you surfing the web. It's still a must have.

This review is for a previous version of the add-on (1.7.1-signed).
