Every once in awhile a browser plug-in will show up in Firefox whether you gave it permission to be there by accident or maybe without any permission at all. A top Mozilla executive is tired of it and has called on Microsoft, Apple and Google to stop the practice of allowing browser plug-ins to install automatically.
Asa Dotzler, the co-founder of the Spread Firefox project and a member of Mozilla's leadership team, says the big three are 'evil' and their plug-ins are being installed without user permission. Dotzler went off on a bit of a tangent on his blog.
