The instructions given below have been contributed to us by users. We have not tested nor verified the completeness and accuracy of these instructions; we provide them for your benefit without any implicit or explicit assurances.
Please note that some of these instructions involve configuring the sofware to trust content from a web site. For simplicity, the instructions have been written assuming you are accessing ADS at its main site in the US, where the hostnames are in the form *.harvard.edu. If you are accessing a different mirror site, please replace the hostname(s) as appropriate.

1. Disable ad blocking alltogether:

* open "Norton Personal Firewall" * click "options" * click "web content" * click "defaults" * click on "ad blocking" * enter: "ads." - then OK3. Create a site-specific web content filtering rule as follows:
* open "Norton Personal Firewall" * click "options" * click "web content" * click "add site" * enter: "adsabs.harvard.edu" - then OK * click "adsabs.harvard.edu" on the left hand side * select the "ad blocking" tab on the right * click "add..." under the empty, white box * select the "permit" option. * enter "ads." in the box. * OKNorton Internet Security
This product is also affected in a similar way. We have not received step-by-step instructions but they should be similar to the ones given above.
