Disclaimer: all the “knowledge” you can find in this post, is obtained by trial and error, documentation reading and years of struggling using GPG. Some information may be out of date or just incorrect. Disclaimer 2: as many others point out, GPG is not the easiest software to deal with. Moreover its codebase is dated and hard to extend. Further, in this day and age is pratically used only by the FOSS community and the “darknet” drug dealers.
Today I decided to refresh my Firefox profile, here is a little log. Why Firstly, I decided to refresh the profile since it was a while I didn’t take care of it. Secondly, my last setup depended on about:config, thus all my edits where “ethereal”. This time I configured everything using the sysadmin way: user.js. The goal of this renewal was to minimize big tech tracking while still preserving Firefox usability, which in my case, comes before any tinfoil paranoia.
