Description
Summary
A java warning pop-up "Firefox has prevented the unsafe plugin "Java" from running on .." (see attachment) while trying to login to JIRA. Pop up is coming up even tho JIRA does not need the use of JAVA applet in the login page.
Environment
- Firefox with Java Deployment Toolkit installed (see toolkit.png).
- Windows only
Steps to Reproduce
- You will need to ensure in your firefox, your java is installed. Can you checked your java here https://www.java.com/en/download/installed.jsp
- Go to your firefox setting, add-on. Go to Plugins. Ensure "Java Deployment Toolkit" is present
- Open Firefox (with the Java Deployment Toolkit installed);
- Access the JIRA dashboard.
- Notice there will be a red warning on the left side of the browser URL box, click on it the warning message will be displayed.
This is demonstrated in the two attached videos:
Expected Results
- JIRA should not cause Firefox to try to run the Java Deployment Toolkit.
Actual Results
- The warning pop-up "Firefox has prevented the unsafe plugin "Java" from running on .." (see attachment) is displayed.
Notes
Firefox is not blocking Java per se, instead it is blocking the Java Development Toolkit from running. What the toolkit does in this case is simply get the version of Java installed. Consequently, there are no side effects of this not running.
Internet Explorer 11 seems to be affected also by a previously downloaded java deployment toolkit. In this case, the browser will prompt the user to let JIRA run java although it's not required for JIRA to function.
Workaround
Please ignore the warning. The Java Deployment Toolkit plugin is known to be insecure and is unnecessary in most cases and therefore it was blocked by Firefox as per https://addons.mozilla.org/en-US/firefox/blocked/p428.
