Good news on the privacy front!: When I recently installed Firefox on a new Android phone I browsed a bit through the settings and noticed that it is now possible to delete all kinds of data when the browser is closed. This includes cookies and offline website data that is often used to track usage. Also, it’s possible to reject 3rd party cookies. Very good, I’ve been waiting for these features for a long time on mobile. It could be that they’ve been in Firefox Mobile for quite some time already but this is the first time I’ve noticed it!
