Is there a way to make Firefox open a new window on a certain URL or raise the tab/window where that URL is already loaded?
I would like to call Firefox with
firefox --open-or-focus http://example.com
and have Firefox either
- open a new window and load http://example.com if no windows are open on http://example.com,
- raise the existing Firefox tab/window that is already open on http://example.com.
Firefox already have a similar functionality embedded in the location bar (try typing an address which you already have in an open tab), is it exposed to the command line as well?
