Specifically, I have seen sites such as www.apple.com fail to resolve from time to time. This does not seem to happen with Safari when I use it. Reproducible: Sometimes Steps to Reproduce: 1. Go to sites such as www.apple.com that you expect to be in DNS. 2. At some point it will hang while looking for that site and then report 3. that the server could not be found. Actual Results: www.apple.com could not be found. Please check the name and try again. Expected Results: It probably should have opened www.apple.com.

I think we've taken some recent fixes, can you check a daily build?

To amplify what Ben C said, please check with Mozilla 1.7 RC1 or later. Specifically, bug 240759 got fixed.

The problem can not be reproduced in 1.7rc. Should this bug be marked as a duplicate of 240759?

Yes. Thank you. *** This bug has been marked as a duplicate of 240759 ***
