Razi3L on "[Plugin: Firefox OS Bookmark] Parse error: syntax error, unexpected T_FUNCTION"

Hello,

I have install your plugin on my wordpress website. The installation went fine. But when I wanted to activate the plugin I got this error :

Plugin could not be activated because it triggered a fatal error.

Parse error: syntax error, unexpected T_FUNCTION in /home1/razi3l/public_html/wp-content/plugins/firefox-os-bookmark/admin/class-firefox-os-bookmark-admin.php on line 158

I was on wordpress 3.7.2. I thought it was because of my old version of Wordpress, so I did update it to 4.0. Unfortunatly I have the same error

Thank in advance.
