Enlarge font in one tab only from the same domain?

more options

I am using a Learning Management System and open several tabs from the same domain. When I open one tab and enlarge the font, Firefox enlarges the font with all the same domain names. Is there a way to customize the about:config so that enlarging the font in one tab has no effect on other tabs?

Thanks,

Mike
