There are now three mainstream flavours of Firefox to choose from: 68.10ESR, 78.0ESR and 78.0.ĮSR is short for Extended Support Release, often preferred by IT departments because it gets security fixes at the same rate as the regular version, but only takes on new features in a staggered fashion – in other words, users of the ESR versions are shielded from sudden switches in appearance, user interface and workflow. Yesterday was both a Tuesday and four weeks since the last major Firefox update, making it the official release date for the latest version.
