I won’t lie, I love to put various themes on all of my electronics if possible. I simply like change. Changing themes on Firefox can sometimes be chore as you have to restart the browser. Granted, you can “save and quit” and have all of your tabs reopen at restart but if you have dozens of tabs open, all of those tabs reloading at once can cause the less apt computer to have a stroke. That’s where Personas come in. They aren’t as deeply integrated as normal themes and are integrated as extensions instead. There are tons of personas to choose from as Mozilla has just released a ton of new ones. As an eye-candy lover, the more the better. However I also like speed and know that the more eye-candy you throw in, the slower your browser will perform. For those with older machines where themes and the other 40 plug-ins/extensions they have installed are starting to slow their browsing experience down should give personas a try. You don’t have anything to lose and they look pretty cool!
