Hello guys. I hope everything is fine at your end . Friends, I have a query and it would be really great if someone gives me some knowledge about it. Well, I know that firefox and yahoo instant messenger are fairly old. I had installed firefox v3.5.6 just some days back and it was working all fine and create any hassles until now. The issue that happened was that the yahoo application state plugin was disabled by firefox. I am unable to guess what the issue is. Please help. I am using windows 7.
