“Summer is here and I would like to introduce you to our
selection of 15 gorgeous Mozilla Firefox themes which you will
certainly like a lot! These Firefox skins will bring in a new
perspective on that boring gray layout. 🙂“The Firefox Themes manager is named Personas and on the
official Firefox website you can find more than 30.000 of them. It
is very easy to install them and all you need to to is to open your
Firefox, click on your big Firefox button and in a drop down menu
you need to pick Add-ons. A new tab appears and on the left side
click on Get Add-ons. After that on the right side of the screen
you will see the Features Personas section.”
