It's been about six weeks since the release of Firefox 20, so assuming Mozilla stays on its usual schedule, Firefox 21 will make its debut on Tuesday
This next version of the popular open source browser
has already attracted attention for the changes brought in early versions to Firefox's “Do Not Track” capabilities
, but those are by no means the only interesting additions we'll see.
Several changes and new features are slated to arrive in the final version of Firefox 21, in fact. Here's a quick rundown of some of the highlights you can expect to find.
1. Three 'Do Not Track' options
As I noted a few weeks ago, Firefox 21 is the first to expand users' Do Not Track options beyond just a single checkbox to indicate that they don't want to be tracked by advertisers. Instead, Firefox 21 now gives users three options
: “Do Track,” “Do Not Track,” and “no preference.”
