Firefox 4.0.1 on Solaris/SPARC crashes frequently if the Adobe Flash plugin is installed.
Downloaded Firefox 4.0.1 tarball for SPARC/Solaris from the contributed directory. It works fine by itself, but if I install the Flash plugin, it crashes within minutes. The same thing occurs with FF4.0 and with any version of Flash, including the current 10.3. OS: Solaris 10 update 9, patched as of May 27, 2011. Hardware: Ultra45 with dual video cards.
This has never been a problem with FF3.x.
Firefox is still broken under Solaris as of FF6. No action has been taken.
