Rated 3 out of 5 stars

Despite being lightweight, this addon is waay too slooow...
I have to wait several seconds for the page to render when changing zoom levels. I have to look at text being written line-by-line when I get to a new page or change zoom level... I have to wait for it to think of something when I get to a page rich of formulas and try to scroll...
Also, at zoom levels <= 130% fonts rendering appears ugly, though on bigger sizes they look OK.
Also, I have to rotate mouse wheel too many times to scroll one page. Would be better if it scrolled more on single rotation.
Still, this is better than nothing. Good to have when you can't install kparts plugin or Adobe viewer.
