What's new in 1.2.0

• One click, one private window. Clicking the toolbar icon now opens a
Firefox Private Browsing window immediately — no pop-up, nothing to
choose. (If the add-on isn't allowed in private windows yet, the click
opens the welcome page so you can finish that one-time setup.)

• Hardened Private Mode removed on Firefox. Firefox has no per-session
scope for those privacy settings, so the old pop-up showed options that
couldn't actually apply to just your private session. Rather than changing
your normal browsing, the Firefox build now leaves hardening out entirely
and never touches your global settings. Session-scoped hardening stays in
the Chromium build.
