Why did my Firefox display suddenly increase while I was using it?

dBm412

Last Friday, I was using gmail via Firefox. While I was typing a business letter, the display suddenly expanded. Now there is no toolbar at the top (I had to access Help > Troubleshoting Information via Google Search!) and it seems to be maximized so that there is no task bar available at screen bottom. This is not a monitor display problem and my IE is normal size.

Hi dBm412,

Try hitting F11. It sounds like you've just accidentally put it in full screen. Don't worry, it's an easy fix. You might also want to take a look at Navigation buttons like back, home, bookmarks and reload are missing.

Hopefully this helps!
