Address autocomplete too slow since the program updated to version 31. I went through all the troubleshooting tips and it still is slow.

Question

I had this same issue with Seamonkey. I have about 4700 names in my address book. When replying to an email, or creating a new email, the auto email lookup function is very slow and unresponsive. It will generally take 10-20 seconds before it starts to work. Since the update to ver 31, now all my collected email addresses are coming up all red color. It is like all history is gone. It doesn't recognize that these email addresses are in my address book or something...thank you.

Answer 1

The spurious red addresses is a known bug:

while the slow operation of autocomplete is probably due to a new feature, that may become a bug:
