I don't know about "safer", but firefox 32 bit plugins work better for me
in genuine 32 bit firefox with no nspluginwrapper. Of course you can get
32 bit firefox in a 64 bit install, but it is less trouble to get it in
a 32 bit install since there isn't a 64 bit version confusing things :-).

Similarly, a 32 bit mplayer (from rpmfusion repos) will be able to access
the windows codecs stashed in /usr/lib/codecs, if you dig up content
for /usr/lib/codecs and you have funky enough multimedia to play that you
need the windows codecs.


I've been 64-bit only for over a year now. I don't regret it.

I use 64-bit Firefox with nspluginwrapper for Flash. In fact, I prefer it. Why? Why? Why? (three times, yes) because nspluginwrapper provides a sandbox environment for plugins. If they crash, Firefox does *not* crash. I can simply refresh the browser to try again instead of having to start Firefox again.

mplayer? Windows codecs? What are you playing? gstreamer-plugins-bad + gstreamer-plugins-ffmpeg are all the codecs you need. I've never run into media that required mplayer and Windows codecs. Aye aye aye, old habits die hard I suppose. Tom, do yourself a favor and dump mplayer.

In the end, you limit yourself if you use a 32-bit only userspace on a 64-bit CPU. How? I suppose if you never need more than 4 gigs of RAM per process, or 64-bit binary applications, you're fine with 32-bit userspace, but why not use the full extent of your CPU?

Of course, if you want to read all of this from a web page, why are you asking this mailing list? Google works on web pages.
