A Tool like Pocket

Is there with Nextcloud a Tool and an Add-On for Firefox in order to save websites as a markdown or in another appropriate manner into NC for reading later? I not only want to make a bookmark, because often I want to clip news or a website subject to change, for later reading. So I want to freeze, clip und archive the content of a website at a specific moment.

I like the default installed app Nextcloud Text (Github). It uses Markdown.

I have shared a md-file (public) and with the link (e.g. bookmark) i can edit it without login into nextcloud. Ok it is a security risk :wink:
With login i can edit it in nextcloud or in the nextcloud app i can edit it, too (iOS, Android).

Works fine for URLs, too.
