This from Xen wiki:

These messages are from a glibc that was built with negative GS register offsets. Xen can run with negative GS register references, but it must “trap and emulate” this condition, which is relatively resource intensive, and quite slow.

If you don’t have a patched glibc, see the no-tls-direct-seg-refs patch mentioned in XenSpecificGlibc.

Most newer distributions are shipped with a “-mno-tls-direct-seg-refs” compiled glibc, but it might not be enabled by default.

Some newer distributions like the RHEL5 Beta1/Beta2 require the ld.so.conf.d trick below to refer to the patched glibc.

Some slightly older distributions like Ubuntu Dapper can be fixed with a simple rebuild of glibc: (see UbuntuDapperHowTo).

echo ‘hwcap 0 nosegneg’ > /etc/ld.so.conf.d/libc6-xen.conf && ldconfig

To ride the bleeding edge with Firefox, check out this site:
https://www.ubuntu-inside.me/2009/05/daily-firefox-35-36-repository-for.html

Summary of ubuntu-inside page: The released and nightly versions of firefox can be installed side-by-side, although only one can run at a time. The repository has 2 firefox packages: the usual branded Firefox package, called firefox-3.5 or 3.6, and the other is abrowser-3.5 or 3.6 which refers to an unbranded build of firefox. Install either one.

Edit sources.list to add the appropriate repository, depending on your Ubuntu release :

While binbash at ubuntu-inside.me describes explains how to install public keys using a script here, I was able to get away with:

$ gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys EF4186FE247510BE
$ gpg --export --armor EF4186FE247510BE | sudo apt-key add -

Then update your index :

$sudo apt-get update

Install Firefox 3.6 you can install 3.6 or abrowser instead of firefox, that is your choice) :

$sudo apt-get install firefox-3.6 firefox-3.6-gnome-support

To run from command line: firefox-3.6
Or from menu: Applications > Internet > Namoroka Web Browser.
To use as default firefox, create link from firefox-3.6 to firefox
