Pop-Up Blocker Interference in Firefox
For Firefox, you can avoid pop-up blocker interference by designating your Windchill server domain as an allowed site. For example, if your Windchill home page URL begins with http://www.mycompany.com/Windchill, you would add "mycompany.com" to the list of allowed sites using the following procedure:
1. Select Options from the Tools menu.
2. Click the Content icon. From the window, click the Exceptions button next to the Block pop-up windows check box.
3. The Allowed Sites - Popups window appears.
4. In the Address of web site field, enter "mycompany.com".
5. Click Allow, then click OK.
For purposes of pop-up blocking, Firefox treats port numbers as part of the host name. If your Windchill server is listening on a non-default port number and you are using Firefox as your web browser, you must add the host name, including the port number, to your list of allowed sites. This means that if your Windchill home page URL begins with http://mycompany.com:8080/Windchill or https://mycompany.com:8080/Windchill, you would add "mycompany.com:8080" to the list of allowed sites.
