Allison, there is, thankfully, a half-way-house if you use FireFox, the No Script plugin (https://addons.mozilla.org/firefox/722/). This lets you white-list the sites you want to get JS functionality on. So if you're reviewing a tool just white-list it!

It really sucks that this level of security is now really needed to be safe, even on a Mac, but that's the nature or our modern world :(
