Hello you two
...and thankyou for your lovely replies!
The version I am using is 10.2.
I did try using Yast (forgot to mention) but the Mozilla Suit didn't come up on the right hand side, and that library file didn't either. I'm surprised that it's not on there as an option! I've installed almost everything to do with Mozilla on there, but still unable to install the Mozilla Suite.
There was also no way that I could open the directory that contains the installation files that I downloaded either, using Yast.
What I'll do now is study that page that you signposted me to. Just reading over it, it seems a bit above my understanding at this time, but I'll keep studying at it until I get it.
Thanks for taking the time,
lots of love,
James
