This bug was fixed in the package firefox - 8.0+build1-0ubuntu0.11.04.3

---------------
firefox (8.0+build1-0ubuntu0.11.04.3) natty-security; urgency=low

  * New upstream stable release v8.0 (FIREFOX_8_0_BUILD1)
    - see LP: #887339 for USN information

  [ Chris Coulson <email address hidden> ]
  * Don't disable our bundled addons on upgrade
    - update debian/vendor.js
  * Modify the UA string to add "Ubuntu" to the platform component
    - add debian/patches/ubuntu-ua-string-changes.patch
    - update debian/patches/series
    - update debian/rules
  * Move custom scripts to debian/build
    - move debian/get-xpi-id.py to debian/build/get-xpi-id.py
    - move debian/refresh-supported-locales.pl to
       debian/build/refresh-supported-locales.pl
    - move debian/extract-file.py to debian/build/extract-file.py
    - update debian/rules
    - move debian/testsuite.mk to debian/build/testsuite.mk
  * Dropped patches fixed upstream:
    - remove debian/patches/build-fix-for-no-ENABLE_YARR_JIT.patch
    - remove debian/patches/compile-pldhash-as-C++.patch
    - update debian/patches/series
  * Refresh patches:
    - update debian/patches/firefox-kde.patch
    - update debian/patches/mozilla-kde.patch
    - update debian/patches/ubuntu-codes-google.patch
  * Shrink the default mozconfig right down so that we use mostly upstream
    defaults, rather than overriding them with our own options. It is still
    possible to override them though. We also drop the pkg-config checks in
    debian/rules which allowed a fallback build configuration when dependencies
    aren't satisfied. Really, the build should just fail here rather than
    continuing in some undesirable fallback mode
    - update debian/firefox-dev.install.in
    - update debian/firefox-dev.links.in
    - update debian/mozconfig.in
    - update debian/pkgconfig/libxul.pc.in
    - update debian/control.in
    - update debian/rules
  * Refresh build-depends, as this hasn't been done for a while:
    - Drop patchutils, libxft-dev, libxinerama-dev, libgnome2-dev and bzip2.
      These aren't needed
    - Drop liborbit2-dev - only required if there is no libidl
    - Add libglib2.0-dev, libext-dev, libfontconfig1-dev and libpango1.0-dev,
      as the configure script checks for these directly
    - Add minimum versions to libgconf2-dev, libgnomevfs2-dev, yasm and
      libgnomeui-dev
    - Specify minimum versions for libnspr4-dev, libcairo2-dev, libsqlite3-dev
      and libnss3-dev when using system versions of those libs
  * Introduce a branch config file (debian/config/branch.mk) which holds
    settings which shouldn't be merged between branches (eg, whether
    the crash reporter should be enabled)
    - add debian/config/branch.mk
    - update debian/rules
  * Move debian/locales.* to debian/config
    - move debian/locales.shipped => debian/config/locales.shipped
    - move debian/locales.unavail => debian/config/locales.unavail
    - move debian/locales.blacklist => debian/config/locales.blacklist
    - update debian/rules
    - update debian/build/refresh-supported-locales.pl
  * Don't open about:blank from the New Window quicklist entry
    - update debian/firefox.desktop.in
  * Touch debian/control.in during clean to force a refresh of debian/control,
    so we can check if it is out-of-date and fail if it is
    - update debian/rules
  * Drop the mozilla-devscripts dependency. We were only using this for creating
    tarballs anyway. Instead, implement our own get-orig-source target, which
    also fixes some problems we were having
    - update debian/control.in
    - remove debian/moz-rev.sh
    - update debian/rules
    - remove debian/mozclient/firefox.mk
    - remove debian/mozclient/firefox.conf
    - update debian/config/branch.mk
    - add debian/build/create-source
    - add debian/build/get-orig-source.mk
  * Lots of workflow improvements for dealing with language packs:
    - update debian/rules
    - add debian/build/extract-file.py
    - add debian/build/dump-langpack-control-entries.pl
    - update debian/build/refresh-supported-locales.pl
    - add debian/config/locales.all
    - update debian/config/locales.shipped
    - remove debian/config/locales.unavailable
    - update debian/control
    - update debian/build/create-tarball.py
  * Fix LP: #887435 - Backport patch from aurora to correctly handle EOF in
    js::TokenStream::getAtSourceMappingURL on platforms with unsigned chars
    - add debian/patches/correctly-handle-EOF.patch
    - update debian/patches/series
  * Turn off the one-time addon selection dialog (LP: #888307)
    - update debian/vendor.js
