problem adjusting screen size

somehow i blew up the screen 4x the normal size while hitting the mouse during a game. i went into settings got it to normal size but now the background is big typing/tabs ect. no biggie but now that the board itself is at normal size and the board is blurry?? i also tried default no luck ...please help thanks!

What browser are you using? In most browsers, "ctrl +" zooms in, while "ctrl -" zooms out.

i tried it doesnt work, im using mozilla  firefox

i just tried it that doesnt work either any other suggestitions?

I use Mozilla Firefox,

You probably hit the Ctrl key and your mouse wheel at the same time.

Try hitting Ctrl+0 (zero). That's the 'default zoom level' shortcut for Firefox.

With all due respect, I don't see Ctrl+0 mentioned anywhere but my post.

yea it worked! thanks dunce, and everyone else that took the time to comment it was ctrl+0 i have no i dea how i managed to that during a game..

My pleasure. Happy chessing.
