Comment 625 for bug 263435

I haven't upgraded firefox for some time. Yesterday i decided to upgrade from version 5.0 to latest version 13.0.1. Most of my plugins stopped working like the Kaspersky virtual keyboard etc. But one thing it's anoying me most it's my keyboard volume buttons stopped working when watching youtube videos. I've uninstalled firefox 13.0.1 installed firefox 5.0 again, voila. All my plugins working great and keyboard shortcuts working again. I guarantee, this problem doesn't exist in firefox 5
