A recent update to either Google's search results page or Firefox's Tab Mix Plus add-on has prevented a locked tab from opening links in a new tab. This Greasemonkey script removes the tracking code on the Google links that causes the problem. I don't understand what the incompatibility is though, since the tracking script just changes the href attribute at the last minute.
