Echofon plugins fails on Firefox
Hello,
I was just using websites through Firefox an error message occurred during my Echofon plugins. I shocked to see this error that suddenly occurred. I am using Win XP so this is not possible for me to fix this issue so I need your assistance. Please help me to get out of this error so that I may continue my work properly without having any issue. Any help would be greatly appreciated. Thanks in advance.
