firefox freezes

yep...it's quite easy to program a memory leak into a plugin by accident that's why looking for updates would always be my first option.
I found out by chance yesterday (while browsing extensions for Chrome) there is a chrome version of invisible hand out there. too
I'm just not buying enough online to justify the use of said plugin.
I also am prepared to pay a few bucks more to a trustworthy source rather than saving a buck with someone I don't feel too comfortable with.

good point, Although unbelievibly one item i was looking for (kids playpen ) was around £100 in a major catalogue retailers (argos)and invisible hand found it £30 cheaper in another reputable store (john lewis) and it was a better one as it had different colours .
