Firefox 69 - Option to add feed to Newsblur

Hi all,

I understand the RSS feed was removed from Firefox >= version 64.
I cannot find any extension that would allow me to add a feed detected directly to Newsblur.

Does anybody have a working setup that lets add a news feed from Firefox directly in Newsblur?

Thanks

Iā€™m using this addon:

It supports Newsblur out-of-the-box, even if the default is set to Feedly.

Thanks a lot !
