Tried a few different RSS feed readers- Either too complicated, or not bright enough. This one is just right. Imported the .opml file, changed the default location to Bookmarks Toolbar, moved the icons to the previous location, renamed, and all is like it was before FF64 came and trashed what users use.. They keep nibbling at what we like to do... anyhow, that's another story. And not a nice one. This addon is definitely the go-to for minimal fuss. Yeah, could do with a colour change of what is read, and an ability to delete the list of feeds... maybe if enough of us say something???
