I was just wondering if there was a way to get the green theme without the lava back round. Like it was with version 5. Any help is greatly appreciated.

I've uploaded it HERE for you and other users who'd like to use it.
It's not necessary to complete the survey thing before download.I haven't put it but you can skip it.

Here's how to install the theme.
1.Save it on your desktop or wherever you like
2.Go to tools-add-ons manager
3.Drop the archive in the add-ons manager
4.Install and restart to see the changes

Enjoy!

I used the boolean trick namely extensions.checkCompatibility for 6 and 7 but the theme wont work on firefox 8 so i was wondering how to fix that because I love the non lava green fox.

I've been a bit busy lately but I've made the old version of Green Fox compatible. You can download it from Here!

How do you bypass the survey or could you post it someplace else to download it from please.

I don't think you can. Anyway try from http://www.mediafire.com/?dqps9a42aqhdwf8

Note: I'm not putting the skip ad thing.

Thank you
