Just What I needed! Rated 5 out of 5 stars

Ever since I started using this add-on my husband hasn't been grumpy with me if I am still working on my computer in bed and he wants to go to sleep early, lol. Nice, simple, yet efficient little add-on to Firefox. It's always updating and has never given me any troubles. Saves me from getting migraines at night, especially after working long hours reading the screen. Thank You, Stefan vd!

This review is for a previous version of the add-on (3.4.27.0). 

Thanks

You are welcome! And have a nice weekend there.
