Context menu is broken on Windows in ESR 45 based Tor Browser
The context menu is essentially unusable on Windows with a ESR45 based Tor Browser. The problem is visible in the browser console:
ReferenceError: Intl is not defined LoginManagerContextMenu.jsm:20:3
We are still compiling Tor Browser for Windows with ICU disabled but there are more and more features in Firefox that rely on it (even if there are still a bunch of them with fallback mode due to Firefox on Android not shipping ICU yet).
