Not a good PDF viewer Rated 1 out of 5 stars
I really don't like this viewer. It's very slow and uses huge amounts of resources. I can't blow up images more than 200% (Adobe goes up to 800%), which I need to read the maps I use every day. It's hard to find the controls. And, worst of all, no one asked my permission to make the change. If I can't use Adobe, I'll have to leave Firefox for something that supports Acrobat.This review is for a previous version of the add-on (0.8.1).
