If your Firefox window shakes, bounces, or jumps up and down erratically, you can try the following actions to address the problem.
Table of Contents
Check extensions and themes
- If you recently switched to a new theme, switch back to the default one - see #How to switch themes.
- If one of your extensions or themes recently updated, try disabling it to see if it is the cause. For instructions, see Troubleshooting extensions and themes.
Check toolbars
- If your Bookmarks Toolbar is showing but it does not contain any bookmarks, either add a bookmark to it or hide the Bookmarks Toolbar. See Bookmarks Toolbar for more information.
- To reset all toolbars and controls to the default settings, follow the instructions to Reset Firefox toolbars and controls.
