how do i enable a certain javascript behavior for a website, sort of like trusting an intranet site?

when i try to use IBM Lotus Notes Domino access from microb, i get this message over and over and over (otherwise it works pretty well)

A script from "International Business Machines Corporation" is requesting enhanced abilities that are UNSAFE and could be used to compromise this device or your data:
Run or install software on device
Modify any open window
Alllow only this abilities if you trust this source to be free of viruses or malicious programs.

is there any way to disable the warning, or trust a site? btw, I don't get a similar behavior with firefox on windows.

thanks,
