Hello everyone, this is my first post here. Anyways to get to the point, this happened about a couple of weeks ago and started when I downloaded the new version of Yahoo Messenger. Without my permission it downloaded it's Toolbar onto Firefox and from then on I was unable to view any of my Extensions within the Addon panel (after first attempting to first remove it using this method). So I then decided that I would restart Firefox in Safe Mode and disable all Addons to see if the Toolbar would disappear. I did that and the Toolbar was gone, but all my extensions were still invisible and no longer worked even when I opened the regular Firefox. Anyways in the panel I seem to have recovered half of my addons by clicking "View Recent Updates" and enabling the ones that showed up. But the rest of my Addons are still invisible and dysfunctional. Sorry for the long post, but I am extremely frustrated and desperate to get this fixed. Any help is greatly appreciated. Thank you.
