In one of my postings, I wrote about the 64bit problems I have with my dual-opteron system. Now I found a application named nspluginwrapper.
nspluginwrapper is an Open Source compatibility plugin for Netscape 4 (NPAPI) plugins. That is, it enables you to use plugins on platforms they were not built for. For example, you can use the Adobe Flash plugin with x86-64 compiled Mozilla browsers.
And now I hope that this tool wil fix it
