SharePoint Online - file modified date updating when user views files in browser

There is an extension for Chromium browsers called "SPO View It" that can resolve this issue.
You can also use Requestly on Chromium or Firefox to create an HTTP redirect filter that changes the end of the URL from "action=default" to "action=view". This changes the default way the file opens from edit mode to view only.
Requestly can also fix the common complaint about PDFs opening in the Sharepoint viewer instead of the normal browser viewer.
