Using Firefox in Ubuntu, I often get a Javascript error message that says evalinSandbox:SyntaxError:syntax error. How can I fix this?

It happens on most, but not all, of the pages I visit. After closing the error message, another one pops up saying "Error: Syntax Error." Closing this window will bring up the initial error message again, and the process repeats five or six times. Eventually the windows will stop popping up and I will be able to view the website, but as soon as I go to another webpage the error messages start again. I've updated both Firefox and Ubuntu to the most recent versions.

hello, this error message is usually caused by the social fixer addon & can be resolved by updating to the latest version available at http://socialfixer.com/blog/category/releasenotes/

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.

Thanks for your help! I had completely forgotten that I'd installed SocialFixer. I ended up removing the program since I wasn't using it, and this appears to have fixed the problem.
