firefox: Update to 101.0

* Under NetBSD/i386 9, rustc consumes all RAM and swap and failed
  to build this package.

Changelog:
New

  * Reading is now easier with the prefers-contrast media query, which allows
    sites to detect if the user has requested that web content is presented
    with a higher (or lower) contrast.

  * It??s your choice! All non-configured MIME types can now be assigned a
    custom action upon download completion.

  * Firefox now allows users to use as many microphones as you want, at the
    same time, during video conferencing. The most exciting benefit is that you
    can easily switch your microphones at any time (if your conferencing
    service provider enables this flexibility).

Fixed

  * Various security fixes.

Changed

  * Removed "subject common name" fallback support from certificate validation.
    This fallback mode was previously enabled only for manually installed
    certificates. The CA Browser Forum Baseline Requirements have required the
    presence of the "subjectAltName" extension since 2012, and use of the
    subject common name was deprecated in RFC 2818.
