A desktop shortcut is placed on users desktops. The shortcut is named “Firefox Private Browsing” and has a custom icon. The “Firefox Private browsing” string is localized.
The default browser file and protocol associations now point to Firefox private browsing mode
These two requirements were dropped. This has simplified things a fair bit, and most likely means that the only platform in scope is Windows (I'm waiting for explicit confirmation of that before closing the Linux bugs).
This also means that some of the work in progress will be shelved. Quick status on the remainging pieces:
A shortcut is pinned to the taskbar. The shortcut is named “Firefox Private Browsing” and has a custom icon. The “Firefox Private browsing” string is localized.
I've got some work in progress on this. There's some behind the scenes implications to how we present Private and non-Private Windows simultaneously, but nothing we can't work through. I should have some useful patches up this week.
Telemetry helps identify sessions that start through the private shortcuts"
This work has not been started yet, but I expect it to be fairly straightforward (we have similar Telemetry already).
