Is it possible, with your particular Linux distribution, to upgrade Firefox to a more recent version? You can try using the internal updater:

Help > About Firefox > "Check for Updates" button

There is no click for updates button when I pull down the about firefox tab. I tried reloading a fresh copy, however it appears to download read only files. The vesion I am using is 11.0

After downloading some updates my email is fine

Please double check that your Firefox is version 28 . If not, read Update Firefox to the latest release

Which Linux distribution are you using?

Are you using a Firefox version from your Linux distribution or did you install a version from the Mozilla server?

If you use a version from your Linux distribution then you need to update via the Ubuntu Software Center.

Also make sure that you meet the System Requirements (GTK+ and GLib) for the current Firefox version.
