Could you post a screen capture of the error message?

Does it happen no matter what page/URL you try or is it only on some pages? (It sounds like you are saying 'all pages', but just want to be sure).

If it doesn't happen on all the pages, could you give a sample URL?

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).

  • Don't make any changes on the Safe mode start window.
