I use a selfhosted FreshRSS instance to manage my rss feeds. I wanted a quick way to add a web page’s rss feed into FreshRSS without copy pasting the URLs. So i created a bookmarklet with the following code to open the freshRSS add-feed page with the URL filled in.
javascript:(function(){
var freshRssUrl = 'https://[FreshRSS_Domain_URL]/i/?c=feed&a=add&url_rss=';
window.open(freshRssUrl + encodeURIComponent(window.location.href));
})()
Of course, update the URL to your FreshRSS domain accordingly in that snippet!
Another quick tip: Did you know that all Youtube channels have a rss feed? I use these rss feeds to get notifications for any new youtube videos on my favorite channels.
