Why does Firefox display only half a page when system is coming out of a resolution change from a game?

more options

When I leave Firefox open in the background while playing Dungeons and Dragons Online, when I close DDO and open Firefox again, it only displays half a page and the bottom browser bar is less than half way down the screen. The rest is just blank space like the browser was shrunk and then enlarged again, but the display window in the browser didn't readjust again. I have to close FF and reopen again to fix it. It used to be that the empty space was white. A recent update now causes that space to be RED when it occurs. Not sure if that helps any. I don't have any other games right now, so I haven't tested this with other games, but this ONLY happens to FF!

Another user posted a screenshot of something like that earlier this afternoon, and I'm not sure what is causing that to happen. I suspect if may be caused by an extension that was recently updated, but no ideas about which one it may be. I just got back to my computer after be gone for the last five hours, so I don't if there has been any additional information in the other thread or not. This is about all I can figure to do right now until we have more information related to this new issue.

Do you have that problem when running in the Firefox SafeMode? http://support.mozilla.com/en-US/kb/Safe+Mode Don't select anything right now, just use "Continue in SafeMode."

If not, see this: http://support.mozilla.com/en-US/kb/troubleshooting+extensions+and+theme...

Here's my screen shot.

So far, it hasn't happened in Safe Mode. I'm going to wait a few days more and then start adding back my plug-ins one by one. What a pain.
