[Greasemonkey] GM + Microsummaries in FF2

[Joe la Poutre]

Hi esquifit,

Wow, a really cool idea to make the generated microsummaries generator
"auto install" - I was thinking that you needed a real XPI type
extension for that, complete with browser/chrome privileges (in order
to write files locally, and register with Firefox somehow).

I have no idea why your approach failed, but I have been unsuccessful
with a test, where I loaded a html file from a local disk (and so
tried installing a microsummary from a file:// url - it silently
failed). I haven't looked any further into this, though...

Still, it would be really cool if this would work from Greasemonkey!
