HELP. Window pops up on Firefox browser that says JavaScript Application, and under that it says 101. There is an OK bitton. when I click OK, up comes the window again. Then after hitting OK again and box goes away, when I move my mouse the box comes up identically again. I even called Apple support. They tried things; told me it may well be some setbold textting in Firefox Preferences. This started right after Mac Update Install upon closing. Any help, please. My browser is totally (obviously) stuck in this loop!!! dreammauiinc@gmail.com jason

Chosen solution

Hi,

Please check if this happens in Safe Mode.

Problematic Extensions

Troubleshooting Extensions and Themes

Uninstalling Add-ons

Uninstalling Toolbars

Safe mode disables the installed Extensions, and themes (Appearance) in Tools (Alt + T) > Add-ons. Hardware acceleration is also temporarily disabled - the manual setting is Tools > Options > Advanced > General > Use hardware acceleration when available. Options > Advanced. All these settings/add-ons can also be individually or collectively disabled/enabled/changed in Firefox normal mode to check if an extension, theme or hardware acceleration is causing issues.
