Now, for a link on the page, open it in a new tab (I did it through the context menu). A second tab window is opened in the same window, except the tabs do not show. It is still possible (in windows) to use Ctrl-Tab to switch tabs and Ctrl-F4 to close a tab, but that relies on people generally knowing those shortcuts. Reproducible: Always Steps to Reproduce: 1. place javascript:window.open('http://www.mozilla.org/','_w_moz','location=no,toolbar=no') in your address bar and press enter. 2. Open any of the links in a new tab. Expected Results: I suggest one of the following: 1) Show tabs regardless of "location" and "toolbar" settings. 2) Disable the "open in new tab" ability. 3) Treat it like an "open in new window" instead. 4) Check to see if another tabbed window is already open and use that. If not found, fall back to opening in a new window. Ideally, I would like to see #4, but would settle for either #2 or #3. I do not think #1 is appropriate, since the usual situations where "location" and "toolbar" are disabled probably do not intend general browsing to happen within that window (and also often set the window to a fixed size, which showing tabs would potentially mess up).
