[newbie] fonts in Netscape

[L. H. LOO]

Greetings, After 16 months to the day, last night I was able to connect to 
the Internet from Linux. But, the web pages displayed in Netscape was very 
small even smaller than this. And in the  View Menu : Increase  Font and 
Decrease Font commands are greyed out.
What can I do please ?
TIA Regards.
