Rated 4 out of 5 stars

Better than the default Firefox redirect blocker, but there is a learning curve. Works best using a whitelist with regexp definitions. Needs a toolbar icon for adding sites to whitelist (or blacklist) like both Noscript and AdBlock Plus have. Then it would be perfect. To use it, first turn off the default Firefox redirect blocker (about:config in location bar -> Toggle accessibility:blockautorefresh to false).
