Firefox displaying Lycos webbuilder incorrectly

I have searched and can't see this problem anywhere but apologies if I have missed it.
I have a website which is on Lycos and I use the lycos webbuilder within Mozilla Firefox version 1.0.6 OS XP home.
Since installing and running Ccleaner, Startup inspector and spyware blaster yesterday the webuilder it is not displaying correctly the fonts are not right and the sections of the screen are not in the correct positions it looks fine in IE, see attached files lycos1 is in Firefox and Lycos2 is how it should look (from IE).
I even tried restoring my system back to a point when I had no problems and uninstalling and reinstalling Firefox.
I am not a PC expert and have run out of ideas as to how to sort this.
I do remember that one of the utilities when installed replaced a dll file but I can't remember which one, would this have caused my problem.
Thanks

 

the dll that was replaced was c:\windows\system32\borIndmm.dll
