Hello,

First open the link in a new tab in the same window, then you click and hold the tab , drag and drop in the other window.

Thanks

No, not manually. I want to do it programatically. There is a command line switch or something? Like Firefox.exe -newtab -www.test.com

Sorry, it wasn't obvious from the question.

Go to Menu Bar, Tools, Web Developer, Developer toolbar or press Shift+F4

In the Scratchpad, type: window.open('http://google.com','_self') //"self" for the same window window.open('http://google.com','_blank') /* "blank" for a new window, but to open in a new window is necessary declare the sizes

Is Firefox your default browser? If you ask Windows to open a URL, it should open in the default browser. You can test by typing or pasting a URL into the Start menu search box.

Or if you prefer to use a more complete command line, see: https://developer.mozilla.org/en-US/docs/Mozilla/Command_Line_Options

Next part is, does the page open:

• in a new tab in the last active window
• in the last active tab, replacing the page
• in a new window

This is determined by various Firefox preferences. You can check yours here:

In a new tab, type or paste about:config and press Enter. Click the button promising to be careful.

In the search box that appears above the list, type or paste link.o and pause while the list is filtered.

(A) browser.link.open_newwindow

3 = divert new window to a new tab (default)
2 = allow link to open a new window
1 = force new window into same tab

The checkbox in Options > Tabs toggles between 3 and 2

(B) browser.link.open_newwindow.restriction - for links in Firefox tabs

0 = apply the setting under (A) to ALL new windows (even script windows)
2 = apply the setting under (A) to normal windows, but NOT to script windows with features (default)
1 = override the setting under (A) and always use new windows

(C) browser.link.open_newwindow.override.external - for links in other programs

-1 = apply the setting under (A) to external links (default)
3 = open external links in a new tab in the last active window
2 = open external links in a new window
1 = open external links in the last active tab replacing the current page

So by default, you would see external links open in a new tab in the last active window.

There is the -new-tab command line as listed in the MDN article switch that you can use.

@toddy_victor and @jscher - This is still manually, not programatically. @cor-el - Thanks man! I think this is what I need!!!!!!
