My suggestion is to use the GUI Package Manager to install Flash. To do this you need access to extras repository. In order to access it you will need a sun on-line account and appropriate certificates for extras repository. Sun on-line registration is free and so are needed certificates. Go to this website [url]https://pkg.sun.com/register/[/url]. It has all needed information. Once you have registered and generated required certificates, download them to some easily accessible directory.
Open the package manager and click on the publishers button. You will have option to add new publisher. It will ask you for a friendly name (what you type in this field is irrelevant) and Internet location. Location of the extras repository is https://pkg.sun.com/opensolaris/extra . It will also be shown on the site from which you can download certificates. Once you put the location in appropriate field, two new options will show up in the window. They will allow you to select location of key and certificate needed to access repository. Browse to location where you placed the key and certificate and select the appropriate file (the other one will be selected automatically). Add the repository. Once the repository is added, you will be able to install software from it. Among other thing you will see installation for flash player which works with Firefox that came with Opensolaris. Install it like any other package (select check-box next to the name and click install button) and flash should work. Although I used a lot of space to type the instructions (you said you were a newbie), this method is in fact much simpler than installation from package available from Adobe. -- This message posted from opensolaris.org
