The icedtea-web binary has just undergone several recent updates (1.2 -> 1.3 -> 1.3.1).
OpenBSD-ports
I was getting a fair number of firefox core dumps and am awaiting the latest patch from my 2nd tier snapshot server.
I had good luck with the older jre/jdk that I built from ports but it was such a PITA (and security hole) that I gave it a pass. If openjdk/icedtea-web is more stable I hope to figure out how to temporarily enable in firefox when needed.
Anyone know if there is something like flashblock plugin?
