Installer une archive firefox

Bonjour,

Je voudrais tester le tout dernier firefox. La distribution nous propose un RPM de la version ESR. Je voudrais autre chose. J'ai trouvé mon bonheur en tar.gz . https://www.mozilla.org/fr/firefox/new/ J'ai chargé et décompressé l'archive.
Le démarrage se passe mal:

(process:25238): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

En prenant soin de bien refermer le firefox ESR on obtient

(process:31309): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

(firefox:31309): GConf-WARNING **: Client failed to connect to the D-BUS daemon:

To circumvent this problem try the following command (with Linux and bash) 
export $(dbus-launch) 

Je met cette derniere commande en place.

puis je réessaye:

(process:22683): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
console.error:

Là j'y croit, mais quand je vais voir la version du firefox qui s'est ouvert, je retrouve ma version ESR. C'est raté.

Je vais tenter de désinstaller firefox ESR pour voir.

Y a t-il quelque chose à faire ?
Merci.
