Chosen Solution

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

This is the same kind of error I have seen SeaMonkey users get.

The DoNotTrackPlus extension has been reported to cause this error.

Check out these add-ons;

Add to Search Bar {web link} Make any pages' search functionality available in the Search Bar


Context Search {web link} Expands the context menu's 'Search for' item into a list of installed search engines, allowing you to choose the engine you want to use for each search.
