Since upgrading to from FF-6 to FF-7, when I click on a text link it doesn't open up in new tab, it just goes to the link within the same window. I've confirmed that I have the tab setting in FF7 set to open a new tab instead of a window, and Google settings set to open links in new tabs, but since the upgrade it all stopped working. No other software has been added or changed, just the new FF7 installed. Any thoughts, or is this a bug?
