As stated in my previous reply I have tried running firefox with all plugins disabled but this did not have any affect on the issue

Type about:preferences#general<Enter> in the address bar.

Under Tabs, check the settings.

I've called the big guys to help you. Good luck.

Thank you for your time and input anyway, I've had a look at the settings but don't see anything that might cause this problem, looks like this might be a bug. Hopefully the 'big guys' will be able to help me out.

I found this in the bug tracker.

Apparently this seems to be a problem with an old hack in XFCE or possibly X-based desktop environments in general, which is no longer supported in Firefox 36. A quick workaround until they fix it, is to open a new terminal and enter:

sudo gedit /usr/share/xfce4/helpers/firefox.desktop (replace gedit with any other text editor that you use) ...and change the final two lines: X-XFCE-Commands=%B -remote "openURL(about:blank,new-window)";%B; X-XFCE-CommandsWithParameter=%B -remote "openURL(%s)";%B %s; to read: X-XFCE-Commands=%B; X-XFCE-CommandsWithParameter=%B %s; and save the document, of course.

This solved the problem for me immediately.

That cured it immediately, strange how every other update has worked as expected until this one. Thanks a lot for the help I appreciate it!
