With the release of the long-awaited Firefox 3.5 tomorrow, I was wondering why web browsers don’t ask (on install) about the sort of items you like to see in search results? Just enough questions to establish a basic ‘search profile’ that could then improve search results — or maybe even silently rework my dumb search terms on-the-fly before they even hit the search-engine? I know signing in to Google is supposed to improve results, over time, but it doesn’t seem to work as strongly as I’d like it to.
