In the past two weeks I have started getting layers and layers of "sandbox syntax error" and "syntax error" from Java Script while browsing using Fire Fox. I have tried to use the helps that are offered but have not found any suggestion to fix my problem. This problem never happens while using Internet Explorer. I love your browser, but am having to use Internet Explorer to avoid great frustration. Help!

This issue can be caused by an extension that isn't working properly (e.g. Social Fixer).

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.
