I cant seem to locate the Firefox directory structure to overwrite with 2RC3. Anyone?
Am I missing something on this installation?

I don't think its wise to delete or overwrite the Firefox that shipped with your distro. I suggest you install Firefox 2.x to a directory such as /opt or /usr/local and then change you icons and menu entries to point to the firefox executable in that location.

I'm currently playing about with the ff2 release candidate. I didn't remove my existing version (since that is managed by my distro's packaging system).

What I did was install it in /opt. I have to launch it using the full path: /opt/firefox/firefox, which while I'm just playing about I do manually using the alt-f2 launcher in KDE.

By the way, I found the flash 7 plugin causes ff2rc to crash, but the new flash 9 beta seems to work more or less OK. It's not 100% stable yet - I find it locks up a little in youtube and the like, but it's not bad. And it uses ALSA finally, w00t!

One more thing to note - backup your ~/.mozilla directory!

Do you have a link for the Flash 9 Beta player?

download the .tar.gz file and if you installed firefox like I said above, just copy the libflashplayer.so file to the /opt/firefox/plugins/ directory.

If you do this you can keep your flash 7 installed on your original firefox installation, and have flash 9 with the firefox 2 rc

You can d/l the plugin from here

They're a bit slashdotted / dug / lq'd at the moment

That's quite possibly a bug with something else in your system indirectly messing with Firefox. I've been running CVS builds of the 3.0 branch for a while now and both Flash 7 and now Flash 9 have worked fine. Just something to consider
