Iced Tea plugin keeps asking for permission to run Java applets

Question

Every time the browser wants to load a Java applet a dialog asking me for permission to run the java applet appears. No matter if I check the option "remember this option" or not, the dialog appears, annoyingly, every time the browser tries to show a Java applet.

Here there's a picture showing the phenomenon.

Is there any solution to this annoying permission dialog?

Thanks in advance,

Charlie

Solution 1

Because of the high number of virus using vulnerabilities of the Java language, Firefox, by default, ask every time if we want to open a Java applet, whatever the system policy.

However, it is possible to change it.

Open the Add-on manager (ctrl+Shift+A) and select the "plugin" tab. Change the combobox next to "IcedTead-Web Plugin" to "Always activate" (Sorry if the name are not accurate, i'm French)

Solution 2

I get exactly the same thing. I believe this is a new java security feature - it happens on all OS's I believe (OSX, Linux and Windows). As far as I can tell, there is no obvious solution, however you could try the following:

1. Open Dash (super).
2. Search "java".
3. Click on "Oracle Java 7 Plugin Control Panel".
   • You may need to install it from the software centre.
4. Click on the Security tab.
5. Change the slider to Medium.

This may solve the problem.

Which browser are you using?

[Charlie]

I'm using Firefox 29.0 that came along with Ubuntu 14.04.

I do not have such a slider under the security tab. Is there a way to whitelist some IP's or a range of addresses?

[Charlie]

Is dash a shell? That's the only dash I know

[Tim]

No, the Dash/Launcher. Press Super, it should open a window with recent files and applications etc. You can search from there.

Unfortunately, I have KDE. If I install Oracle Java 7, should I uninstall the icedtea plugin?

[Charlie]

I thought it was going to work, but no luck :(

Have you tried to purge and reinstall icedtea plugin?

[Charlie]

I did it, but no luck :(

Yes, do remove icedtea if you get oracle.
