Screen Size HELP?

[766]

When I log onto Youtube from Firefox, the video screen size for the video is way too big and it hurts my eyes! Whenever I watch a video, it is way too large now - how can I make it smaller? The only other option at the bottom of the screen is to make the video full size - no option to make the video smaller.

But when I use another search engine (like Google Chrome) the video screen size is the normal size.

What happened on Firefox to make the Youtube screen size too big?

It is too big and it hurts my eyes. How can I make the video screen size smaller on Youtube when I am using Firefox?

Thanks!
