In the age of censorship we may need ways to save a web page offline or even online. Never rely on online services, your copy of the web page can get deleted at any time. There are various ways to save a web page.
To save it online, go to https://archive.ph (which is archive.org) and search for the page to see if it exists. If it doesn’t exist, enter the full URL in the correct box, and click the button to save it.
In a Chrome-based browser like Chrome or Brave, go to the burger menu with 3 horizontal lines, click More Tools, then Save Page As. Save this to your local file.
If you want to use a Chrome extension try SingleFile. https://chrome.google.com/webstore/detail/singlefile/mpiodijhokgodhhofbcjdecpffjipkle
