Hi Timothy1610, Try - Menu -> Help -> Troubleshoot Mode... Firefox will restarts and a Troubleshoot Mode options window will appear. Do NOT select Refresh.

With Firefox closed, first make sure Firefox is not running in the background, then, hold down the Shift key while launching Firefox. (If the Profile Manager opens, select a profile and then hold down the Shift key again while clicking the "Start Firefox" button.)

Troubleshoot Mode is a debugging startup mode available where all added extensions are disabled, the default theme is used, and default localstore settings (toolbar settings and controls) are used. Troubleshoot Mode also disables hardware acceleration, the Just-in-time (JIT) JavaScript compiler, and any changes made via userContent.css and userChrome.css. Any changes made to preference settings remain in effect in Troubleshoot Mode, however, and all available plugins are used.

To summarize:

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

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