Hi lgcampbell,

Try going to Tools > Add-ons > Appearance. This will show you all the themes/personas you have installed. You'll know which one you are currently using because it will have a Disable button displayed.

You can find more information on using and managing personas in the Knowledge Base article Use themes to change the look of Firefox.

Hopefully this helps!

A Persona may not last forever, so if you like a persona then it is best to make a backup copy of the two persona image files in the profile folder in case they get removed from the persona server.

If you like a persona then it is always best to save a copy of the files lightweighttheme-header and lightweighttheme-footer in the Firefox Profile Folder.

Firefox only stores the images from the currently selected persona.
All others that you have installed are loaded from the server when you select a different persona.

Can you tell me where Firefox stores it's appearance files (my current persona) as I'd like to tweak it a bit in my photo editor ?

You can see that in my above post.
The current persona consists of the two files lightweighttheme-header and lightweighttheme-footer (no file extension) in the profile folder.

You can use this button to go to the Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Open Containing Folder

Thanks for that. I didn't know where the profile file was, so your info helped me find it. The header file is not a normal graphics format but I was able to use Irfanview to rename it as jpg and so I have retrieved it and can now work on it.
