NoScript is a great plug-in, both for security and for ad blocking. However, I've found it's not always easy to figure out what scripts need to be permitted on certain pages, to be able to use the features I want while still blocking unnecessary scripts. Many times, it's not simply sufficient to turn on scripts for the domain of the site you're visiting.
For example, to use StackExchange to its fullest I've had to enable scripts for:
In the past, I've generally just figured this out through trial and error. However, that is most definitely not the way it should be done. It leaves me vulnerable to still possibly running malicious or advertising scripts during that trial and error phase, which could lead to irrecoverable damage.
Most of the time, this issue arises when I want to use a certain feature on a website but the script is hosted by a different domain. I usually start by enabling the "usual suspects" like domain.tld, domaincdn.tld, domain-images.tld. Still, this doesn't always work. And, slightly beside this matter, there's really no intuitive way (short of running a WHOIS query, and trusting those results) for me to be certain that domain-images.tld is owned and controlled by the same people running domain.tld, or that its scripts are actually offering any functionality that I want.
Is there an additional plug-in or other method which can be used for me to figure out which domains/scripts need to be whitelisted for me to use certain features of a website? Preferably, the method should not require knowledge of any scripting languages or require the user to interpret the sites' source code.
My concept of an "ideal" solution would be a plugin that allows me to right-click any interactive page element (button, hyperlink, flash object, etc) and see a list of sites that host scripts required for that element to perform its function. It should also allow me to right-click an empty spot in the page, and see what domains host scripts that affect the layout and formatting of the page.
