Usually after a minute or so, the computer screen responds and I am able to complete what I was doing.

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.

Try to decrease the value of the pref network.http.max-connections from 255 to a setting like 30 as used in Firefox 3 versions.
