I continually get a Java error. I've uninstalled and reinstalled firefox and nothing has helped. I've updated flash and Java.


I have used Firefox as my default browser for many years. I've recently started getting a Java error message. It pops up continually. I have updated flash and java. I have uninstalled and re-installed Firefox and nothing has helped. I have had to start using Chrome instead of Firefox which I don't care for but I don't have the java error with Chrome. How do I fix this problem? The error reads as follows: Java Script Application Error: syntax error

Your JavaScript error has nothing to do with the Java plugin . It is likely caused by an added extension (the earlier forum threads /questions/944619 and /questions/943088 mention disabling or updating the Social Fixer extension will resolve the problem).

You can read this article for help troubleshooting your extensions: Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
