Rated 3 out of 5 stars

I like the idea of helping Mozilla with firefox, but it's annoying how often the add-on pops up messages in the lower right of my screen to announce tests or survey's I've already completed. Yes, I'm ALREADY RUNNING the Tab Open/Close Study - you don't need to remind me about it!

This review is for a previous version of the add-on (0.2.1).
