I have a small site for a non-profit which has a 11 forums (one for each trail page): http://skylands.njwildlifetrails.org.  Each page's forum is set to use the corresponding DEFAULT FORUM for each trail.

Issue #1: 

The menu items for each trail work OK in Internet Explorer.   For example, clicking on the first menu item for Swartswood Lake trail takes a page with this link:

http://skylands.njwildlifetrails.org/SkylandsTrails/SwartswoodLakeTrailSussexCounty/tabid/142/forumid/2/scope/threads/Default.aspx

However, in Firefox, clicking on the same menu item goes to the page with the following link:

http://skylands.njwildlifetrails.org/SkylandsTrails/SwartswoodLakeTrailSussexCounty/tabid/142/Default.aspx

Note that the page address does not include the default forum id and therefore all of the forums are listed.

Issue #2:

On the home page, I also have a Links module with a link  to each of the pages.   When any of these links are used in either browser, the default forum is not used.  Instead the complete list of forums is displayed.

Note that I have to have this up and running by Monday, so I may resort to changing the links and menu items to URLs with the default forum embedded in each n(instead of just simple specifying a page).

Thanks in advance for your help (and thanks for the previous help).

Mike
