JavaScript moveTo(0, 0) not working in FireFox OS X

Here’s a weird JavaScript FireFox bug…

In OS X, for some reason the following javascript was not positioning the FireFox browser window to the top left of the screen.

window.moveTo(0, 0);


Not sure what causes the problem but it seems to work find if you position the window 1 pixel lower.

window.moveTo(0, 1);
