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.
Steve,
Two issues:
1. It is about:plugins you should check, not about:config
I was checking about:config because I thought there might have been
settings in there that needed to be toggled to enable java.
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.
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.
regards,
Steve
Hope this helps,
