Nothing? In Mozilla, you check one box and forget it.
Your procedure involves turning off all scripting, then turning scripting back on for 'trusted sites' one at a time. And by the way, if I have turned off all scripting, and visit a site which works better WITH scripting, how would I know?
There is a big difference: the Mozilla solution is elegant, the Microsoft solution is cumbersome and ass-backwards.
Did you not just get finished saying that Mozilla blocks pop-up scripting except for sites that you allow?
How do you allow them? When you go there you put them in a "allow" flat file and from then on they're allowed for that site?
Same as IE.
As for the rest of the scripting IE tells you that there's script on the page that's being blocked. Which is fine because scripting is over-used. In my surfing I've decided around 90% serves no useful purpose and seems to be written by people who took a Introduction to Java class and thinks that makes them uber |_33t haXorZ.
There's only 4 or 5 sites I can think of, where I find scripting acceptable.
Ironically - though not surprisingly - the worst-scripted site on the entire internet is probably Microsoft.com.
lol.
