It is great as it does exactly what it says! Is there anyway to make a certain percentage, for example 200% as the default that every new window or tab automatically opens to?

I made a firefox account just to be able to leave a review of this masterpiece. Thank you for making this I've never been happier. This made my life easier that I can say.

Good

Great add-on.
I just hope to make it fixed for all websites, or at least, for browsing session.
