Review for Focus Regainer by Jorge
Rated 5 out of 5 stars
It's working on Firefox 37.0.2. Works on YouTube and on flash games.
Focus Regainer won't work on YouTube when I'm using the "Ad Remover" function from the add-on "YouTube Enhancer Plus". However, if I turn of the "Ad-remover" it works perfectly while using YouTube Enhancer Plus. I can still block ads using Adblock Plus so I can still enjoy ad-free YouTube while I use Focus Regainer and YouTube Enhancer Plus.
