Fix for extraneous tabs
There is a problem with browsers (such as Flock) based on the Firefox engine when you click an external link such as from an email. The effect is that although the link opens in the browser, it will open two tabs, each of which loads the same URL. This has been known for some time, and I had corrected it in my previous version of Flock and Firefox, but since installing the new version that same problem has returned.
