This bug was fixed in the package firefox - 23.0+build2-0ubuntu0.12.04.1

---------------
firefox (23.0+build2-0ubuntu0.12.04.1) precise-security; urgency=low

  * New upstream stable release (FIREFOX_23_0_BUILD2)
    - see LP: #1208039 for USN information

  * Build conflict on python-progressbar, as having this installed causes the
    jit test harness to fail
    - update debian/control.in
  * Disable unsupported W3C webgl tests
    - update debian/testing/extra/mochitest/mochitest.json
  * Refresh paths for a11y tests after landing of bmo: #854868
    - update debian/testing/extra/mochitest/mochitest-chrome.json
  * Make firefox-globalmenu a real transitional package
    - update debian/control.in
    - update debian/build/mozbuild.mk
  * Just test the selected locale on all channels in test_langpack_chrome.js,
    rather than testing we get a correctly translated string. This is just
    way too fragile
    - update debian/testing/extra/xpcshell/package-tests/test_langpack_chrome.js
    - update d/p/test-integration/automation-output-junit-xml.patch
    - update debian/patches/unity-menubar.patch
    - update debian/patches/dont-override-general-useragent-locale.patch
    - update debian/patches/no_neon_on_arm.patch
  * Drop crashtest-no-network-access.patch as the test seems to have been
    removed from the tree
  * Always build the crash reporter and Breakpad symbols on supported
    architectures, even if it is disabled at run time. Will hopefully avoid
    surprises by the time we reach beta (where the crash reporter is enabled)
    - update debian/rules
    - update debian/build/mozvars.mk
    - update debian/build/mozbuild.mk
  * Rename mozbuild.mk => rules.mk and mozvars.mk => config.mk
  * Shut up lintian
    - update debian/copyright
  * Make the transitional globalmenu package priority extra, section oldlibs
    - update debian/control.in
  * Make the testsuite priority extra, section misc
    - update debian/control.in
  * The testsuite shouldn't depend on essential package libc-bin
    - update debian/control.in
  * Override symlink-is-self-recursive warning in the testsuite, as this is
    intentional
    - add debian/firefox-testsuite.lintian-overrides.in
  * Remove the executable bit from the testsuite zip file
    - update debian/build/rules.mk
  * Remove the executable bit from searchplugins
    - update debian/build/rules.mk
  * Silence an embedded-library warning and some image-file-in-usr-lib warnings
    - update debian/firefox.lintian-overrides.in
  * Drop firefox-gnome-support. It was only depending on libraries that are
    already guaranteed to exist when firefox is installed (mostly, glib).
    Firefox has no need to depend on libnotify for the time being either, but
    if it does again, that dependency should just be on the main package
    - update debian/control.in
    - update debian/build/rules.mk
    - remove debian/firefox-gnome-support.install.in
  * Only blacklist Firefox in Apport on official builds

    - update d/p/test-overrides/disable-failing-python-tests.patch
    - update debian/patches/unity-menubar.patch
    - update debian/patches/fix-broken-langpack-install-manifests.patch

  * Update test-fixes/mochitest-browser-plugincrash-with-no-crashreporter.patch
    to just not include the test on !MOZ_CRASHREPORTER builds
  * Fix build-time xpcshell tests after landing of bmo: 597064, by
    using the python virtualenv provided by the upstream build system
