Firefox generally takes action based on the Content-Type indicated by the server, rather than the file extension. Fingers crossed that the server is sending those *.GPX files with a distinct content type.
(1) You can try changing the behavior for the specific content type on the Applications list on the Settings page. This article has the steps:

(2) If the file type you want to manage is not listed there, try this next:
- Expand the Downloads list
- Right-click the file
- Click Always Open Similar Files to instruct Firefox to use the default application for that content type in the future
Firefox then should add that file type to the Applications list with a "Use [default application]" action.
If you prefer that Firefox "Always ask", that can't be set through the right-click context menu, but you can select that on the Settings page (see the article listed under #1).
(3) If that contest menu menu item is missing for these downloads, the site might be misidentifying the file as generic binary content instead of identifying it as a specific content type. This is harder to work around. I can suggest an add-on if you encounter this frequently.
