Yeah, you gonna need to give more context!
Your comment has no baseline.

Sorry, didn't check the GitHub.
There's a pattern of users sharing early builds of their software, I was jumping to a conclusion.
Android user too.

Currently don't own a desktop, any chance someone converts the framework to be functional as a user script, we already have one that blocks instances.

Android users can install the user script using Firefox,

• https://www.xda-developers.com/mozilla-general-extension-support-firefox-for-android-nightly/
• https://www.ghacks.net/2022/10/20/firefox-beta-for-android-now-supports-custom-add-on-collections/

1. Sign Up/In to your account & add all the necessary add-ons to the collection in it starting with the one already compatible with our browser otherwise, the list will be empty.
   https://addons.mozilla.org/en-US/firefox/collections/
2. Go to the Settings page, scroll down to the bottom.
3. Tap on "About Firefox".
4. Tap on the Firefox logo 5 times. It will display a message that says "Debug Menu enabled".
   If you go back to the Settings page, you'll notice that a new option is available under the Advanced section.
   It's called Custom Add-on Collections.
   Tap on it, and it will ask you to enter the collection owner's ID, and the collection's name.
   The ID is a unique 6-digit number that can be found in your add-on collection's URL.
   The name of course refers to the collection's name, unlike the number this is something that you can choose.
   For example,
   https://addons.mozilla.org/en-US/firefox/collections/***926754***/***ghacks***/
   The ID for this collection is 926754 and the name is ghacks.

Using this method with Mull & Tampermonkey.

I hope it will be compatible with FreshRSS

FeedMe is a good example to build upon, using their stable version personally

To test the RSS implementation & find if a domain has one:

Temporary workaround to view the RSS feed before adding it to your aggregator
