Firefox already has an excellent cloud-based Sync system for sharing settings and browser history between computers — but perhaps you don’t want any of your data stored on remote servers; or you keep separate work and personal profiles; or you don’t want to have to set it up in several places (like short-lived virtual machines); or maybe you just like to keep all your settings in plain text files you can copy around.

I fall into several of those categories, but until recently, I didn’t know Firefox had a built-in solution.

Last year at PyCon I organized a small Open Space event for OpenPGP key signing. Based on the success of that event I'm doing it again this year at PyCon 2015 in Montréal. We'll be in room 512cg at 18:00 on Saturday the 11th.

I wrote up a very short superficial guide that covers what this is all about, how to get started, how key signing happens, and where to go from there; you can read it here.
