If this happens on multiple different sites, it could be caused by an add-on that is trying (failing?) to access the pages or modify itself in response to the pages.

You might just disable all nonessential add-ons here and then restart Firefox and see whether that helps:

  • orange Firefox button or classic Tools menu > Add-ons > Extensions category
  • orange Firefox button or classic Tools menu > Add-ons > Plugins category

Can you post a link to your site so we can check it?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
