Firefox live bookmark default feed

OK, I had a previous problem with live bookmarks not parsing certain characters in my feed titles. Upon inspection I realized that it was because Firefox was grabbing the Atom feed when creating a live bookmark. Is there anyway to ensure that when clicked the firefox live bookmark rss icon will add the rss 2.0 feed instead of the atom feed? ie. https://www.blogname.com/feed/rss2/ instead of https://www.blogname.com/feed/atom/

Thanks.
