RPM of the second Beta of next major version of Mozilla Foundation browser is available in remi repository for Fedora 12 and 13. Available for 24 locales.
The firefox4-4.0-0.2.beta2 package install this new version besides the version 3.x. So you will have 2 entries in the Internet menu.
WARNING : a backup of your profile (~/.mozilla/firefox directory) seems mandatory.
Start by reading :
As always :
yum --enablerepo=remi install firefox4
No xulrunner update, this RPM provides his bundled Gecko engine.
Actually most of the extensions and themes are not compatible and will be disabled.
I start to test the new features and I expect yours feedbacks.
A first SunSpider JavaScript Benchmark reveal a great performance improvement in 64bits.

Commentaires
Ca fonctionne du feu de dieu ! En deux mots ? "Merci Remi !!"
There's an issue with selinux that will prevent firefox 4 to start.
$ firefox4
/usr/lib/firefox-4.0/firefox-bin: error while loading shared libraries: /usr/lib/firefox-4.0/libxul.so: cannot restore segment prot after reloc: Permission denied
To fix issue with SELinux, execute these two commands :
audit2allow -M firefox -l -i /var/log/audit/audit.log
semodule -i firefox.pp
Rather than use the audit2allow command ; a simple chcon does the trick:
Thank you Remi for this build ;)
