Firefox window is janky, sometimes hangs for a few seconds, when trying to move the window around.
This is a problem when moving the window around on Windows 10. Safe mode solves the problem. Turning off all plugins and extensions does not work. REFRESH does NOT work. What could be the problem?
Using Firefox 50.0 on Windows 10.

Hi, if you have a theme, try disabling it.
Also try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
- Click the menu button
and select Options on Windows or Preferences on Mac or Linux.
- Select the Advanced panel and then the General tab.
- Uncheck Use hardware acceleration when available.
- Restart Firefox and see if the problems persist.
If the problem is resolved, you should check for updates for your graphics driver by following the steps mentioned in these Knowledge base articles:
