+Subject: [PATCH 01/24] Block Components.interfaces,lookupMethod from content
+
+This patch removes the ability of content script to access
+Components.interfaces.* as well as call or access Components.lookupMethod.
+
+These two interfaces seem to be exposed to content script only to make our
+lives difficult. Components.lookupMethod can undo our JS hooks, and
+Components.interfaces is useful for fingerprinting the platform, OS, and
+Firebox version.
+
+They appear to have no other legitimate use. See also:

+Subject: [PATCH 02/24] Make Permissions Manager memory-only
+
+This patch exposes a pref 'permissions.memory_only' that properly isolates the
+permissions manager to memory, which is responsible for all user specified
+site permissions, as well as stored STS policy.
+
+The pref does successfully clear the permissions manager memory if toggled. It
+does not need to be set in prefs.js, and can be handled by Torbutton.

+Subject: [PATCH 05/24] Block all plugins except flash.
+
+We cannot use the @mozilla.org/extensions/blocklist;1 service, because we
+actually want to stop plugins from ever entering the browser's process space
+and/or executing code (for example, AV plugins that collect statistics/analyse
+urls, magical toolbars that phone home or "help" the user, skype buttons that
+ruin our day, and censorship filters). Hence we rolled our own.
+
+See https://trac.torproject.org/projects/tor/ticket/3547#comment:6 for musings
+on a better way. Until then, it is delta-darwinism for us.

+Subject: [PATCH 07/24] Make Tor Browser exit when not launched from Vidalia
+
+Turns out the Windows 7 UI encourages users to "dock" their Tor Browser app
+for easy relaunch. If they manage to do this, we should fail closed rather
+than opened. Hopefully they will get the hint and dock Vidalia instead.
+
+This is an emergency fix for
+https://trac.torproject.org/projects/tor/ticket/4192. We can do a better
+localized fix w/ a translated alert menu later, if it seems like this might
+actually be common.

+Subject: [PATCH 11/24] Limit the number of fonts per document.
+
+We create two prefs:
+browser.display.max_font_count and browser.display.max_font_attempts.
+max_font_count sets a limit on the number of fonts actually used in the
+document, and max_font_attempts sets a limit on the total number of CSS
+queries that a document is allowed to perform.
+
+Once either limit is reached, the browser behaves as if
+browser.display.use_document_fonts was set to 0 for subsequent font queries.
+
+If a pref is not set or is negative, that limit does not apply.
+
+This is done to address:

+
+Solves https://trac.torproject.org/projects/tor/ticket/4017.
+
+Yes, this is an ugly hack. We *could* send the observer notification from
+Torbutton to tell the download manager to switch to memory, but then we have
+to dance around and tell it again if the user switches in and out of private
+browsing mode..
+
+The right way to do this is with a pref. Maybe I'll get to that someday, if
+this breaks enough times in conflict.

+Subject: [PATCH 16/24] Prevent WebSocket DNS leak.
+
+This is due to an improper implementation of the WebSocket spec by Mozilla.
+
+"There MUST be no more than one connection in a CONNECTING state. If multiple
+connections to the same IP address are attempted simultaneously, the client
+MUST serialize them so that there is no more than one connection at a time
+running through the following steps.
+
+If the client cannot determine the IP address of the remote host (for
+example, because all communication is being done through a proxy server that
+performs DNS queries itself), then the client MUST assume for the purposes of
+this step that each host name refers to a distinct remote host,"
+
+https://tools.ietf.org/html/rfc6455#page-15
+
+They implmented the first paragraph, but not the second...
+
+While we're at it, we also prevent the DNS service from being used to look up
+anything other than IP addresses if socks_remote_dns is set to true, so this
+bug can't turn up in other components or due to 3rd party addons.
