• The letter grade now shows on the toolbar icon.
• Site history, weekly tracker counts and the tracker network map are now saving properly.

Note: Firefox dashboard data from before 2.3.1 is incomplete and cannot be recovered.

Leak detection and blocking. Shield now watches the email, phone and name fields
you type into, and catches a page sending that value to a third party before you
press submit. It names who received it and offers to stop that recipient, on this
site or everywhere, taking effect on the page you're already looking at.

Shield now names the script that read your field, including scripts that read a
value you never submitted. Filtering by destination cannot see a read at all.

The data-request generator is now free for everyone.

Tracker coverage went from roughly 24,000 domains to 92,000+. Earlier releases
shipped a truncated portion of the upstream filter lists; this one ships all of
them.

Premium is now the exposure ledger: the accumulated record of every company that
received something you typed and every script that read one of your fields, with
a dated export.

Per-site protection

The popup now has a "Protect this site" toggle above the global controls. If a page breaks, you can turn Shield off for that one site instead of switching it off everywhere.

Unchecking it whitelists the site you're on. Rechecking removes it, including any parent entry that covered it. The change applies straight away, with no reload.

Available in all ten languages.

Tracker lists refreshed from upstream EasyList and EasyPrivacy.
