Just notified that (Microsoft's) Silverlight plug-in for Firefox has been blocked due to vulnerabilities. I've had it disabled for 3 years (ie, have never used it). Under Firefox's Add-ons no version, new or old, exists. I figure it's time to junk it.
But unlike extensions there is no apparent way to remove the plug-in. I suppose I could go into about:config and set about deleting anything which has the Silverlight designation, but I'm extremely reluctant to do such in the event that so doing could compromise something else (such as total functionality).
Any thoughts regarding the dilemma?
