Firefox and Chrome Rated 5 out of 5 stars

Today I tried to download a YouTube video using this add-on in Firefox, for some reason, it failed,. So I went to Chrome, installed this add-on, and then tried to download the same video, then I received the error saying: "Sorry, the video cannot be downloaded as it did not abide to Google policy", something like that (I couldn't remember the exact wording'. And I guess it's because YouTube and Chrome are owned by Google, that's why it prohibited users from downloading any YouTube videos. I went back to Firefox and tried again, and this time, I was able to download the YouTube video successfully.

This review is for a previous version of the add-on (3.8.8.1-signed).
