I am happy !! Rated 5 out of 5 stars
Should be include in Firefox basic. Since 1.5 year I was looking for an addon wich can zoom pages ou text only. This one do that and it is very light (8k) and easy to use. Just one click or right-click on an icon in statut bar. And in bonus, you see magnification %, so when you come back in other session on this website, you can control this %.
