While working with Rational Functional Tester (RFT) on Firefox browsers, if enablement test failures are observed, then I follow the below steps to resolve them. These can be checked to avoid enablement issues.
1 Launch RFT as Administrator.
2 Make sure same version of JRE is enabled in RFT and the Firefox browser.
Refer the links on how to enable JRE and browser in RFT https://www.ibm.com/support/knowledgecenter/api/content/SSJMXE_8.6.0/com.ibm.rational.test.ft.doc/topics/RunJavaEnabler.html
3 Launch the Java Control Panel from Control panel and verify the Java version
4 The version should be the same which is enabled in RFT and browser . If that is not the case, then Add the correct version and enable it.
5 If Security Level under Security Tab is set to Very High or High , then set to Medium or low
6 Under the Advanced tab, make sure the settings are as below:
Console can be hidden later , but enabling it will help to ensure that correct version of JRE is associated with the browser (remember that there could be multiple JRE associated with the browser). Disable next-Generation Plug-in unless it is compulsory.
