Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7a) Gecko/20040128 Firebird/0.8.0+ It takes 3s for Firebird to open the Go menu after I open a new window. This makes the Go menu useless for me. My history setting is 20 days and history.dat is 5MB. My CPU is a 1.6 GHz P4.
I was getting similiar issues until I cleared my history (set to 31 days).
