Personas is a great Firefox feature. However .....
Your FAQs state "Themes change the appearance of Firefox. A Persona is a special type of theme that changes the look of your browser without changing the navigation buttons, toolbars, and menus. Until now, to apply a theme you needed to install it and restart your browser, like with extensions and other add-ons. Now, with Personas you can instantly preview a design and install it in one click without needing to restart."
Not so, ALL Personas, no matter the author, require restarting to activate, and the Theme resorts to the default Theme, not the Theme in use.
Please correct. Thank you.
Switching to the default theme when you install a persona is why you need to restart Firefox. If you would be using the default theme and would install a persona, a restart isn't needed. Also, by design personas are only enabled with the default theme. There was an experimental version of the Personas extension made back in the days of Firefox 3.6, but the results of allowing an add-on theme along with a persona didn't work out to good.
Thanks for your reply. It would seem that one can use Themes or Personas, but not both. They cancel each other out. That is the very thing I was wondering about when I clicked on FAQs, but Firefox's description seemed to imply that both can be enabled: "A Persona is a special type of theme that changes the look of your browser without changing the navigation buttons, toolbars, and menus." But in fact Persona does affect the graphics of a non-default Theme's navigation buttons, toolbars and menus. I think your description of how Themes and Personas are different needs to be amended. It is confusing and incorrect. Clearly state that Personas can only be enabled with the default theme. Thanks the opportunity to comment.
