Firefox 3.0.5 / oclite v1.0 plugin - possible bug ??

OK I've just 'updated' from portable Firefox 3.0.4 to 3.0.5 & when starting I get message stating that 'oclite plugin is not compatible with 3.0.5' (or words to that effect)

Looking in the Plugins - & 'oclite' is disabled (as per normal incompatible plugins)

However there's no 'Uninstall' option avaliable, all buttons are greyed out ([Options] / [Enable] / [Uninstall] )

So what exactly is this 'oclite' plugin ??

I guess it's part of the original Firefox installation (Bug reporting/Crash feedback perhaps ??) that's been overlooked when it's made as a 'PortableApp'

Is it ?? - and how can we remove it from the plugin list
