White bars have appeared on the sides and bottom of my full windowed browser. I downloaded nightly as well to see if the issue persists, and sure enough, it does. I understand that this may not be strictly Firefox-related, but I can't seem to find help anywhere else. Also, this issue does not happen in any other application. I also uninstalled, and installed a fresh copy of Firefox as well. Same issue persists. Attached is a screenshot of the issue. Thanks!

In your uninstall of Firefox did you also remove all the data files? ... if not, then the problem may sill exist in there....

One of the things to always try first is to restart Firefox into safe-mode ... post back on your results...

Try running Firefox in safe-mode... NOTE: This is a testing procedure only ... NOT for normal browsing.
-- On the menu bar, click the Help menu and select Restart with Add-ons Disabled....
Firefox will start up with the Firefox Safe Mode dialog. Click continue in Safe Mode and don't check any items.

Note: You can also start Firefox in Safe Mode by holding down the shift key while Single/Double clicking on the icon.
* (option key while starting Firefox on Mac).

-----------------------------------------------------------------------------------------
>What safe-mode does ..... Safe Mode temporarily affects the following:
* All extensions are disabled. --- * The userChrome.css and userContent.css files are ignored.
* The default theme is used, without a persona. --- * The default toolbar layout is used.
* The Just-in-time (JIT) JavaScript compiler is disabled. --- * Hardware acceleration is disabled.

-- Safe Mode has no effect on the following --
* The status of plugins is not affected.
* Custom preferences are not affected.

This is the link to the main KB article for Safe-Mode ... but, use the above info 1st...

Dfoulkes,
Thank you very much! Looked at the original install location, saw some files still there. Should’ve known, since when I ran the installer for the second time, it detected that I had installed it originally. No need for safe mode (yet), but I’ll keep it in my tool belt for sure. Thank you!

From your answer it's hard to tell if you are still having this problem. If so, check to make sure you are not running Firefox in compatibility mode. Right click the shortcut you use to start Firefox and choose properties. In the dialog that opens, click on the Compatibility tab. See if "Run this program in compatibility mode for" is checked. If it is, turn the checkbox off and restart Firefox.

Are you possibly running Firefox in some sandbox environment ?

Try to boot the computer in Windows Safe Mode with network support.

Problem is solved. Sorry for the confusion.

When I do run Firefox in a sandbox environment, I see no problems. Not sure what the (original) problem was, or what caused it.
