I have been having a lot of crashes so I updated my Firefox to version 54.0.1 (32 bit). Now I get this error msg when I open Firefox: 

             TypeError: bundlePreferences is null1715

I also put it here as an attachment. I want to know what this means and how to make it go away. Thank you.

This issue is probably caused by an extension that isn't working properly.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
