Pale Moon forum

It is probably not something many people would bother with any more, I only possibly need it to access a hardware firmware web type interface page, so I guess I will try some other things, but the iced tea java plugin does seem to crash on many test pages with Pale Moon unstable.

java-runtime-common-3-1 jre-openjdk-11.0.3.u4-1 jre-openjdk-headless-11.0.3.u4-1 libnet-1.1.6-3 icedtea-web-1.7-1

Of these pages that still exist, many plug in tests result in a crash. Some you get a dialogue to run with javaws which then works OK.
2.2 IcedTea-Web plugin test sites:

Or here:

Firefox 52 ESR users: If you'd like to run the verify app as a plugin, please click here.
If you'd like to crash Pale Moon with icedtea please click here
Perhaps it is unimportant as no one else seems to have noticed but it certainly causes a lot of crashes!

The icedtea-web-1.7-1 plugin also doesn't work in Firefox esr52, using a prebuilt binary from Mozilla, it freezes the browser and threw a bunch of errors after starting that from the command line. But after removing icedtea-web, but keeping java-runtime-common-3-1 jre-openjdk-11.0.3.u4-1 jre-openjdk-headless-11.0.3.u4-1 libnet-1.1.6-3 nss-3.43-1, then manually downloading the genuine Oracle java jre-8u211-linux-x64.tar.gz from their website, and doing Java is working in both firefox esr52 and more helpfully in Pale Moon too.
So I'm npapi happy.

The above solution does not entirely work in all circumstances as the Arch icedtea-web plugin provides javaws too, so to run jnlp files you have to download them then run them manually.
