Tabbed Browsing in Mozilla

[canary_joe]

I recently downloaded the tab browser extensions for the Mozilla browser. I keep changing the colour to all my tabs at the top of my browser but everytime i shut down my browser and re-open it at a later time, the tabs have changed back to all being the same default colour. Is there any way to set these so the tabs stay the same colour as what you set them to using the extensions?
Thanks for any suggestions.

Isn't Tabbed Browsing a basic tool of Mozilla?

You could always try by reinstalling it?
