No, not to always open a link in a new window. Whether a link opens in the same window or a new window depends on the the page creator specifying new or blank for that link. Firefox can divert the new/blank window to a Tab instead, which is the default setting.

If you don't want tabs when a new/blank window is specified, deselect the pref for Open new windows in a new tab instead in Tools > Options > Tabs

Thank you! I am getting more used to the tabs instead of a new window opening, like Internet Explorer does. At first it freaked me out and I thought I lost where I was at! lol I've figured it all out. Too bad, though, that Firefox won't let me change that default to always open a link in a new window. But I guess there are worse things that I could have a problem with. Have a great day!
