Java Access in Firefox

[Stephen Morris]

Hi,

I am currently using Firefox 49.0a1 on both Linux and Windows and 
on both systems Firefox will not activate Java, this has been the case 
for several versions of Firefox. I have to java plugin in the 
appropriate mozilla directories, but Firefox will still not use it. I 
have also checked about:config and there appears to be no java entries 
in there whatsoever.

Does anyone know any way to activate Java in these versions of Firefox?

regards,

Steve

You shouldn't have to do any manual linking or copying.  Install the 
icedtea-web package and it should just work.  I've been using it for a 
long time.

I have installed the icedtea-web package and have placed a link from the 
firefox plugins directory to where the icedtea-web package installs the 
plugin. This needs to be done because the upstream version of 64 bit 
firefox is compatible with Ubuntu and not with Fedora.

Why aren't you just using the Fedora packaged Firefox?

Because I wanted to use the same version of Firefox across all of the 
operating systems I use. I use the nightly version of Firefox.

Steve,

Two issues:
1. It is about:plugins you should check, not about:config
2. You say what version of firefox, but not what version of Java JRE
you're using.
OpenJDK 7? OpenJDK 8? Oracle Java 7? Oracle Java 8? what sub-version?
eg Java8u91 is the latest. !  Release date April 19, 2016.

This is important because Firefox now blocks plugins deemed insecure
(with open 0day bugs). So if you have an older Java installed (say
Java 7 update (latest -1)) then Firefox will indeed block it. The
latest version available usually runs just fine (unless you try to use
it on the window between the discovery of a 0day and when the next
update that plugs that hole is released).

Always check on https://java.com/en/download/ for clear info on what
thje latest release is and its release date. OpenJDK usually follows
suit and when there's a Java 7 or Java8 update the security fixes flow
back to the OpenJDK code base, and a corresponding OpenJDK 8uXX is
released

3. You might want to hurry, as the official plan going forward RSN is
to deprecate the plug-in (might come as soon as Java 9 / OpenJDK 9),
also known as  "no more browser applets". Java desktop apps and apps
launched vua Java Web Start wont be affected.

Hope this helps,
FC

I was checking about:config because I thought there might have been 
settings in there that needed to be toggled to enable java.

I am using the latest version of openjdk that is in the Fedora 
repositories, but for some reason Fedora has installed the headless 
package (the one without audio and video support). My problem has turned 
out to be that the upgrade from Fedora 22 to Fedora 23 has not installed 
the icedtea-web package as part of the upgrade. I have now installed 
this package and placed the required link to the plugin in the Firefox 
plugins directory (this is required because upstream 64 bit Firefox is 
compatible with Ubuntu, in terms of directory structures, but not with 
Fedora) which has now activated Java.
