How to save a web page in Opera as a single file?

Question

Opera

I have been using the Opera browser for several years, I got used to it and do not want to switch to another browser. Save interesting and useful web pages to your computer in MHTML format. But after a recent browser update, this possibility has disappeared. Tell me how you can configure Opera so that you can again save a web page in MHTML format. The MHT format is not of interest, because. some browsers do not open it, the PDF format is also not interesting, because. cuts off part of a web document.

Answer 1

Installing Chrome extensions
Version 2.5.7 by Opera Software

Answer 2

Install the "Save AS MHTML" extension.
Opera is the same Chrome, only with a different interface.
