Nothing wrong on my end ( using Firefox v23.0.1 ) All seems well
Try to do a manual update for Adobe Flash for IE and Non-IE, as well a new JAVA has been released -- try to update these as well aside from clearing your cache and cookies ( using CTRL+SHIFT+DEL to open the Clear All History window, or using CCleaner )
Nangyari din po saken yan last week, sabi nmn po nila I clear up lang yung caches and history ng browser mo then restart your PC. everything else will be fine. All is well nmn na po sa side ko
