both are closed-source and only 32bit
so if you do go 64bit you might have to install the 32bit libs and a 32bit version of Firefox
saying that hardly anyone uses REAL and FLASH will have V9 out for linux in the new year (present version for win is 8.5 and for linux 7!!!) and Adobe says a 64bit version will follow
Yup - It's annoying that Macromedia Flash is 32 bit only because all distros will install 64 bit version of Firefox which does not work with 32 bit version of Flash. I wish I knew how to load Debian 64 with Firefox 32/Flash 32.
