This update bumps the package to the latest stable version containing a
few security fixes:
- CVE-2018-12392: Crash with nested event loops
When manipulating user events in nested loops while opening a document
through script, it is possible to trigger a potentially exploitable
crash due to poor event handling.
- CVE-2018-12393: Integer overflow during Unicode conversion while loading JavaScript
A potential vulnerability was found in 32-bit builds where an integer
overflow during the conversion of scripts to an internal UTF-16
representation could result in allocating a buffer too small for the
conversion. This leads to a possible out-of-bounds write.
Note: 64-bit builds are not vulnerable to this issue.
- CVE-2018-12395: WebExtension bypass of domain restrictions through header rewriting
By rewriting the Host request headers using the webRequest API, a
WebExtension can bypass domain restrictions through domain fronting.
This would allow access to domains that share a host that are
otherwise restricted.
- CVE-2018-12396: WebExtension content scripts can execute in disallowed contexts
A vulnerability where a WebExtension can run content scripts in
disallowed contexts following navigation or other events. This allows
for potential privilege escalation by the WebExtension on sites where
content scripts should not be run.
- CVE-2018-12397: Missing warning prompt when WebExtension requests local file access
A WebExtension can request access to local files without the warning
prompt stating that the extension will "Access your data for all
websites" being displayed to the user. This allows extensions to run
content scripts in local pages without permission warnings when a
local file is opened.
- CVE-2018-12389: Memory safety bugs fixed in Firefox ESR 60.3
Mozilla developers and community members Daniel Veditz and Philipp
reported memory safety bugs present in Firefox ESR 60.2. Some of these
bugs showed evidence of memory corruption and we presume that with
enough effort that some of these could be exploited to run arbitrary
code.
- CVE-2018-12390: Memory safety bugs fixed in Firefox 63 and Firefox ESR 60.3
Mozilla developers and community members Christian Holler, Bob Owen,
Boris Zbarsky, Calixte Denizet, Jason Kratzer, Jed Davis, Taegeon Lee,
Philipp, Ronald Crane, Raul Gurzau, Gary Kwong, Tyson Smith, Raymond
Forbes, and Bogdan Tara reported memory safety bugs present in Firefox
62 and Firefox ESR 60.2. Some of these bugs showed evidence of memory
corruption and we presume that with enough effort that some of these
could be exploited to run arbitrary code.

Misc cleanups, but mainly this:
Before:
- `version` could mean either Firefox or TorBrowser version,
- `configureFlags` was hacky.
Now:
- `ffversion` is Firefox version, `tbversion` is TorBrowser version,
- `configureFlags` is much less hacky.
This update bumps the package to the latest stable version containing a
few security fixes:
- CVE-2018-12386: Type confusion in JavaScript
A vulnerability in register allocation in JavaScript can lead to type
confusion, allowing for an arbitrary read and write. This leads to
remote code execution inside the sandboxed content process when
triggered.
- CVE-2018-12387
A vulnerability where the JavaScript JIT compiler inlines
Array.prototype.push with multiple arguments that results in the stack
pointer being off by 8 bytes after a bailout. This leaks a memory
address to the calling function which can be used as part of an
exploit inside the sandboxed content process.
