Yes. Since version 3.5 (iirc), Firefox comes with its own forked version
of xulrunner. The system-wide copy of xulrunner is distinct from the one
bundled with the Firefox package. Same for nspr (the Netscape portable
runtime) and nss (the netscape SSL implementation). And if you happen to
use Thunderbird, you've even got a third copy of all these libraries in
your system.

Following the best traditions of Windows applications, Firefox and
Thunderbird will store passwords, proxy settings and file associations
in two different locations.

Seeing this, the Chromium developers promptly reacted by bundling a
dozen of large system libraries into their codebase, including ffmpeg,
libicu, openssl and sqlite. Some of these have been diligently forked to
ensure that packagers wouldn't accidentally try to use the system
