- Download Mozilla-NSS SlackBuild from AlienBOB
- Grab the latest version of nss and nspr
- Edit the version in mozilla-nss.SlackBuild script and execute it
- Install Mozilla-NSS package
- Get the RPM package for Adobe AIR
- Convert to TGZ using rpm2tgz and install it
- Voila..... you can now access RIA Gallery from Adobe or Fresh Air Apps to test whether it works or not
I tested it on Slackware-Current 32 bit using Firefox
