Firefox Tip: Open search results in a new tab

When you Ctrl+K to the Google search box in Firefox, type your terms and hit Enter, the results appear in your current tab - but it’s easy to make ‘em open a whole new tab so you don’t lose your current page. The How-To Geek explains:

Type about:config into the address bar, and then put the following into the filter box: browser.search.openintab. Double-click the value to change it to true.

You can also use Alt-Enter when you search to open a new tab optionally.
