javaScript is by default enabled on FF, but when I close/reopen it, the status reads as not enabled. Why doesn't it save the enabled state?

In FF If I type in WhatIsMyBrowser.com, type I see "No javascript is not Enabled". I then type in 'about:config' in the address bar and see that javascript.enabled is true...but if I close/reopen FF, it reverts to "not Enabled". Is there a simple 4-5 step method of enabling javascript so that it stays enabled? Thank you.

If javascript.enabled is true and stays true after a restart and the website reports that JavaScript in disabled then you likely have an extension that blocks JavaScript.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

Firefox shows a blueish highlighted shield icon at the left end of the location/address bar in case Tracking Protection is blocking content. You can click shield icon for more detail and possibly disable the protection. You can check in the Web Console what content is blocked.
