i really need to PERMANENTLY DISABLE the infernal, default auto-refresh session on return to already opened tab. tyranny of the default on Android. if/when i want to refresh that session, i'll do so MANUALLY. i want this, not only in alpha, but beta & standard, too. so, it just can't be buried in about:config, which is nanny-state removed from standard. it must be exposed in UI Settings. i'm not the first or only to request this.
