Firefox warning message: Add-ons may be causing problems
This article applies to:
The following window appears while launching Firefox browser with the warning:
Firefox has determined that the following add-ons are known to cause stability or security problems
Older versions of the Java Deployment Toolkit (DT) and the Java Plugin have been disabled by Firefox. Some Java versions are flagged by Firefox as 'Add-ons may be causing problems'.
If Firefox thinks an add-on is unsafe and can cause a security risk, it will block it from loading.
In case of a soft block Firefox will present a warning message but will allow the user to continue if they wish but with compromised security. In the case of a hard block Firefox will block installation so that the user cannot use this add-on. To resolve this, the user should update to latest version of Java.
By upgrading to the latest available Java versions for Java 6 and Java 7 releases should resolve the issue.
» Update to the latest version of Java 6
» Update to the latest version of Java 7
