I can&#x27;t wait to use a Servo (and Rust) based multi-process browser with a lean HTML5 UI. We wait for E10s since 2011 or so, and it still defaults to 1 process and is experimental. The whole XPCOM and XUL legacy API cruft do hurt Firefox. Phoenix&#x2F;Firebird&#x2F;Firefox originally started as a lean fork of the Mozilla Suite, with a lot of old cruft removed. Nowadays, I wish there would be a new leaner fork, that kisses the old cruft good bye and starts fresh with Servo and TraceMonkey.<p>Maybe Mozilla should refocus all resources to Servo and Rust... All what people expect from Mozilla is a lean modern fast independent open source browser.
