Firefox 57 coming soon: a Quantum leap (Fedora Magazine)

The upcoming Firefox 57 release presents a challenge to distributors, whohave to decide when and how to ship a major update that will break a bunchof older extensions. ThisFedora Magazine article describes the plan that Fedora has come up withfor this transition. "Users probably shouldn't 'hold back at FF56 asmy favorite extensions don't work.' Recall that security fixes only comefrom new versions, and they'll all be WebExtension only. The ExtendedSupport Release version will also switch to WebExtensions only at the nextrelease. This date, June 2018, marks the deadline for ESR users to migratetheir extensions."
