So I am running openSUSE Tumbleweed up-to-date as of the time of posting this thread. I just downloaded Firefox ESR (current version is 52.0.1) because I plan on using Citrix Receiver and need Java to work. Installed on the system as per default is:
nlsthzn@linux-buv5:~/Downloads> java -version
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (IcedTea 3.3.0) (suse-3.1-x86_64)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
Problem is java is not showing up in Firefox. Just came from Ubuntu 16.04 where it was showing up and working fine in Firefox ESR.
Any suggestions, comments would be greatly appreciated.
I don’t know if there is still a Java dependency, if so then verify that the Iced Tea plugin is installed in your Firefox (it should be by default. If not, install it).
So I was distro-hopping again and again in Ubuntu based distro’s I am able to download the TAR file with Firefox ESR and if I install icedtea plugin via the package manager it shows up in both version of Firefox, the one installed via the package manager (latest available) and the ESR version I downloaded and extracted.
Now on openSUSE Leap and the java plugin shows up in the normal version of Firefox (as it seems the normal installed version is also the ESR version) but on the separately downloaded ESR version from the Mozilla website the plugin doesn’t show up?
Any ideas why? (I simply want to understand more about how Firefox knows about the plugins to use etc. and the differences between openSUSE’s and Ubuntu in this regard).
Firefox ESR is also packaged and maintained in the Mozilla repo https://software.opensuse.org/package/firefox-esr
but as there are mozilla rpm’s used by other apps you might have to do a full vendor change to the mozilla repo
to install firefox-esr and get security updates do
zypper ar -f http://download.opensuse.org/repositories/mozilla/openSUSE_Tumbleweed/mozilla.repo
zypper in firefox-esr
about the plugin showing up in the standard build of Firefox
it’s my understanding that npapi will be alive for some time to come but mozilla will only allow Adobe’s flash player to run
it’s the same thing as their unsigned addons policy they can run but mozilla blocks them on their builds
opensuse’s build of Firefox does not block anything plugin or addon and I like it like that
mozilla’s build blocks unsigned addons and npapi plugins other then flash
