''<p>jandsfowler [[#question-1389818|said]]</p>'' <blockquote>Apparantly I need to download the latest version of Mozilla Firefox to enable my browser to work properly Please help </blockquote> It appears you are using Windows Vista? Of so then the most current version of Firefox you can run on Vista (and WinXP) was the old EOL Firefox '''52.9.0''' esr you appear to be using. The Firefox versions since 530.0 and later has '''required Windows 7 at minimum to run'''. Either you can update Windows to 7 or later (windows 10 would be best option) or you could try dual booting with a light Linux distro to use the current versions of Firefox. If you do try Linux, I suggest to use a lighter desktop like Xfce and not the heavier KDE or Gnome and make sure packages like FFmpeg is installed. from https://www.mozilla.org/firefox/53.0/system-requirements/ <blockquote>Windows Operating Systems (32-bit and 64-bit) Windows 7 Windows 8 Windows 10</blockquote>
