L'animation flash de quelques sites (en particulier le site winds-up, alias Baston) se bloque sur firefox sous fedora 15 32bits (mais pas en 64 bits !)

Ce plugin est disponible dans le paquet nspluginwrapper ; son rôle :

• d'après nspluginwrapper.org

nspluginwrapper is a proxy plug-in and viewer for NPAPI browser plug-ins. It allows browsers to run foreign plug-ins built for a different architecture, most commonly to run a 32-bit plug-in in a 64-bit browser

• d'après Wikipedia

NSPluginWrapper is a cross-platform compatibility plugin for Netscape 4 (NPAPI) plugins. That is, it enables the use of plugins on platforms they were not built for. For example, you can use the Adobe Flash Player 9 (Linux/i386) plugin on Linux/x86_64, NetBSD, and FreeBSD platforms along with a native Java Virtual Machine (JVM) in the same browser. NSPluginWrapper is also useful to confine native plugins into a specific execution domain for reliability and security purposes.

NSPluginWrapper also provides a standalone plugins player. This program makes it possible to execute plugins without an actual web browser.

It is mostly built to run i386 plugins on AMD64 architectures.

Malgré toutes ces bonnes intentions, c'est bien lui la cause du problème, car voici :

yum remove nspluginwrapper et le problème est résolu.

Reste à voir si cette suppression ne pose de problèmes par ailleurs…
