That's the add-on I looked for! I hate Firefox' behavior and this addon fixes it. Thank you!

It works as described, but opens tabs only in foreground.
Is it possible to open tabs so, in background, if they are opened in background without this addon?
What do you mean by "background" ? can you describe the steps so that I can reproduce it ?
