[Greasemonkey] Inspecting / Modifying global in-page variables in 0.6

[Gareth Andrew]

Anthony,

This doesn't appear to be a greasemonkey problem, unsafeWindow should
behave exactly as window does in regular javascript.  It seems to be a
firefox 1.5 bug/feature.  The bug can be seen in the attached html page
without using Greasemonkey.  
Sorry this doesn't actually help solve your problem, but i've got my
thinking cap on.  Le us know if you solve this problem via another
avenue as I'm sure it would be of interest to other script developers.

Gareth.
