I am running Peppermint 3 on a Dell Latitude 505.
I noticed today that some websites viewed on Firefox 24 have lost some functionality and one or two told me that Java/script was not enabled.
The package manager has a long list of Java-related files shown as installed (not that I understand their meaning!).
Chromium is working fine but I prefer Firefox.
I would be grateful, as usual, for advice.
in firefox, go to
about:plugins
(entered into the address bar)
is java listed, and enabled ?
Hi Mark.
No, it’s not there.
Listed are: Shockwave Flash, Quicktime, windows media, Divex Browser, Realplayer 9 and gecko-mediaplayer.
I had already searched the Add-on library for Java but only QuickJava was listed. I installed it but that didn’t solve my problem. and JavaScript was not listed.
What’s the output from:
dpkg -l | grep java
and
dpkg -l | grep jre
The outputs are attached.
There appears to a lot of redundancy.
Output from:
dpkg -l | grep icedtea
don’t post it as an attachment … post it inline in your next posting
The first two were a bit long, I thought, for posting; hence the attachments.
Here the new output:
ii icedtea-6-jre-cacao 6b27-1.12.6-1ubuntu0.12.04.2 Alternative JVM for OpenJDK, using Cacao
ii icedtea-6-jre-jamvm 6b27-1.12.6-1ubuntu0.12.04.2 Alternative JVM for OpenJDK, using JamVM
ii icedtea-7-jre-jamvm 7u25-2.3.10-1ubuntu0.12.04.2 Alternative JVM for OpenJDK, using JamVM
ii icedtea-netx-common 1.2.3-0ubuntu0.12.04.3 NetX - implementation of the Java Network Launching Protocol (JNLP)
run:
sudo apt-get install --reinstall icedtea-7-plugin
then close ALL web broswer instances, and restart firefox.
is java now listed at
about:plugins
Sadly not; only icedtea.
but is java now working ?
were you originally saying java worked in chromium, but not in firefox ?
My apologies: I assumed that because it wasn’t listed it would not be functioning, so got on with some other work. No patience, you see!
The websites of interest now work in Firefox - thank you.
During my experiments before trying the Forum, I installed QuickJava which has functions that I don’t understand, with icons that just clutter up the screen. I have a feeling that it is simply a method of controlling different aspects of the installed Java.
Can I delete it? or am I now relying on it?
Yeah, get rid … if it breaks anything, we can fix it
Hmm … sounded a bit like Bob the Builder there :o
Done - and nothing fell over.
Very many thanks for your help, Mark. You’re a gent. Not many of us left.
You’re welcome
