I am looking for an alternative for adobe flash player plugin to solaris firefox browser since adobe no longer supports it in solaris. Could someone tell me if there is one. 
wall:
Just to be honest, flash under Solaris couldn't support "everything" even when "supported". So I suppose the good news is that some of the open source flash attempts might actually come closer to being "Solaris flash" since it was always a bit limited anyhow. I'm actually surprised that somebody is using Solaris as a client/desktop, you are dying breed.
Getting gnash to work with lastest firefox on Solaris could require getting the sources and doing some builds (unless somebody else has already done the work).
