This, not the "official" Containers add-on, is the true successor of Multi-Fox - but is an improved design that actually works well in tabs!
This has been awesome for our employee's and Makes multiple PeopleSoft windows actually possible once again, like they were when we used MultiFox. Thank you, thank you, and thank you.
This program is thus-far glitch free and amazingly feature-rich. The options settings are amazing.
This functionality should be STANDARD-FEATURE in Firefox. Since you can only have one Private-Session in firefox, this is perfect. Why the heck FireFox doesn't let multiple Private-Windows each have their session/self-containment, I will never know.
But this works, and works well. And you can customize the hell out of it. Very professional-level software for a mere add-on.
