I turn off JS for ALL google accesses except a monthly incursion into Base. I haven't used G as a search tool for ages but any site coming at me with anything google on it gets G banned even if I allow the site domain itself. NoScript is easy to switch. If I usually use ixquick for search but sometimes Bing. Neither has JS enabled on my browser.
I run a mail server for my customers and hate having to send them stuff at gmail addresses because I know it will be intercepted, even if only by another computer. My customers' web site Control Panels all include a line of code that looks for google toolbar and blocks access if found.
I find it's quick to use. For example, if I find a site that I need to access I hover over the Options button on the bottom browser bar and select (usually) "Temporarily Allow example.com" - if I trust the site and intend returning frequently I may select permanent instead.
That is usualy it, although some complex sites require two or three domains to be enabled (a pain which the designers ought to be made forcibly aware of with a red-hot keyboard!) but enabling two or three domains or (if google ain't one of them) "temp enable all on this page" isn't much more time consuming. Couple of seconds tops, maybe two or three times a day for me.
