Because Firefox and all other products apart from B2G don't have the "jsloader.reuseGlobal" pref enabled, so they still get a new global per XPCOM JS file / JSM, which means a global variable is equivalent to defining a member on `this`. Now, maybe Fennec might want to flip this pref as well (it would make a lot of sense IMHO) in which case we might want to re-evaluate how much this would affect Fennec add-ons (IIRC they're all JetPack-based, no?). Desktop Firefox is probably better served by waiting for forthcoming optimizations from the JS team. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
