Maybe there need more options in multi-workspace environments?
E.g.:
1. new window unconditionally
2. new window if none on an active workspace, new tab otherwise [hidden in Windows]
3. new tab unconditionally

and also a checkbox to focus the window when link has been opened (having it checked would probably move the user to another workspace in case 3). Probably, the same preference mentioned in Comment #0 could be reused here.
