I use NoScripts to block scripts in Firefox, and NotScripts in Opera. It’d be great if similar functionality combined with a comprehensive whitelist of known safe sites could be developed by yourselves and implemented into the next version of Dragon. The whitelist would mean far less frustration to the end user, as using NoScripts/NotScripts can be quite annoying at first when webpages don’t display correctly. If you have a whitelist of the most common safe sites, that would save people lots of trouble.
I used the same script blockers in FireFox and Opera myself so after recently making Comodo Dragon my goto browser I’m trying to decide if I have need a similar extension.
