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
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,
