Good news! Mozilla has decided to recommend Pearltrees to their community by “featuring” the pearler ” in its gallery of browser extensions.
Firefox has always been important in the development of Pearltrees:
– The first pearler we developed was for Firefox
– Code for Pearltrees pearler  has been released under GPL and available here
– The Firefox community has been very welcoming and positive towards Pearltrees.

In still more good news, a new version of the pearler for Firefox was released yesterday!  To get it, go to your account, click the “pearler” button, finish the installation process and enrich your collection of pearls.
