Having a hard time reading text with how small everything is. (can't imagine how it must feel like for older folks)

for a second i thought it was my computer but other sites display normally.

couldn t see an option to use larger font in my profile options.

is it the same thing for everybody or did i mess up something ?

It is the usual size for me. When I first started reading your problem my first thought was that you had changed the text size on your internet browser, but since other sites display normally for you then that isn't it. Maybe try clearing your browser's cache???

ok just seen why,

it is a firefox option : must have pressed ctrl + - by accident. Ctrl + 0 get display back to normal.
