I have a large blank space(line) in Firefox window at the bottom that can not be removed. Please help!

This appears when I am working in full screen mode. I cannot remove it. I have tried starting Firefox in safe mode, uninstalled Firefox, but nothing helps.

Is this on every webpage? On every website?

Is it possible that is the end of the page?

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Thank you for your questions. This happens only when using Firefox. Other programms (ex. Excel, Outlook, Adobe) are working fine. This affects only my main monitor. 1 have 2 monitors. Starting Firefox in Safe mode is not helping unfortunetaly. Is it not the end on the page. When I drag the Firefox window in other monitor, the problem disappears. We have 15 computers in our office and we are having the same problem on almost all computers, so this is not a unique problem for my computer. Also I have tried disabling " Use hardware acceleration when available". Your help will be really appreciated.

Yes, it is the same type of monitor as the one not having problems. And yes, this error is on every website. We believe it could be related to CPU or video card resource?
