It has been remade by someone else. See the new one here,I like it too :) Install the latest Personas Plus. Then, follow this to install a persona. (taken from the addon page)

1. Enable the Persona of your choice, restarting the browser.

2. Enable Kempelton Reloaded (or any Persona-compatible theme), restarting the browser.

3. Type 'about:config' into the location bar

4. Search for 'lightweightThemes.isThemeSelected'; toggle this so that it is true.

5. Restart the browser.

Hope this helps...

THANX for the reply. Unfortunately it didn't work. The "lightweightThemes" was already on "True" when i checked it. I installed the "personas 1.6.2", but the "kempelton reloaded 4.1.3" theme didn't work with any of the personas i have. I tried to install the "personas 1.4" like i use to have, but its not compatible with FF9. I guess alot of the personas aren't compatible with FF9 yet. I'll keep trying though.

Strange. Seems to work for me. Try it with a clean profile of firefox (START > RUN > firefox.exe -p make a new one to test etc) and if that works, then its the settings/addons on your firefox/firefox profile.

Does it work without the Personas Plus extension being enabled?

THANX for the reply Tomatoweb. I'll give it a shot. I posted the same problem on the mozillazine forum and someone posted a link to their site listing the basic method like you posted along with an alternate method. I'm going to try the alternate method & if it doesn't work, then I'll create a new profile to see if its the addons/extensions/settings thats causing it.

THANX for the reply Cor-el, unfortunately it doesn't work with the personas plus 1.6.2 extension being enabled. Someone on mozillazines forum posted this to my post about this problem: "Mozilla decided quite some time ago that Personas shouldn't work with Themes despite years of them working together just fine, and engineered Firefox 3.6 and 4.0 specifically to not allow them to work together. They promised us they would fix the situation and since then the main engineer working on Personas either left or has been too busy to contribute and fix the mess." I posted a 2nd reply to Tomatoweb above & will try what someone else on mozillazines forum said to try on their site using an alternate method. I hope it works.
