Looking for a FireFox Add-On

[jp_bl_68]

Does anyone know if an add on exists that would let me open a tab within the same active window? By that I mean rather than having each tab as a separate page, two tabbed windows could be viewed side by side so I could easily view the two pages at the same time.

If such an add on does not exist in FireFox then does anyone know if a different browser has this option?

Not sure if this actually lets you have individual sets of tabs in each window but it's worth a shot.

Thank you, that's exactly what I was looking for. Cheers.
