> The whole crux upon which the colorways marketing rested, was they were temporary! You get to change your theme for a few months, and then later on at some random point, it changes again as it's taken away from you.
It was sort of a marketing gimmick, one I wasn't particularly fond of. (I was the lead engineer for colorways.) What it really meant is that we'd offer the onboarding screen and colorways built into about:addons for a limited time. The intent was never to remove them once users installed them. We have since migrated them to AMO where they can still be installed: https://addons.mozilla.org/en-US/firefox/collections/4757633...
