Hello! I need to password protect or prevent deleting history from opera browser (and any other browsers on my PC).

Is it possible? How?

It does not make any sense. This data exists only on the client side; and the client has fool control over this data, which can be purged at any time. In contrast, your Web application cannot access or limit the user's access.

To protect the privacy of the users, there are limitations to how JavaScript can access this object. Hence browsers will not allow you use methods other than those mentioned below.

  • length - Returns the number of items (URL's) in history

  • back - Loads the previous URL in history list

  • forward - Loads next URL in the history list

  • go - Loads a specific URL from history list

I voted 4. You see, you information looks correct and is certainly very good to know, but you don't mention the possibility to limit the access, and I feel that OP would need some help in practical conclusion.
So, I added a short answer more to the point, please see.
