Opera Mini is a widely recognized web browser today. However, this browser does not support downloading videos directly from YouTube. Today, we will explore a clever trick to achieve this.
Steps
By Modifying the URL

Visit the YouTube website.

Locate the YouTube search bar and enter the name of the video you wish to download.

Select the desired video from the search results list. Note: Do not click to watch the video.

Navigate to the browser's address bar – where the URL is entered. You will see an address starting with (m.)

Remove (m.) and type (ss) (without a period).

Press OK. A new page will open, allowing you to download the video.

Choose your preferred format and click the download button.

Opera Mini will prompt you to select a download location. Pick the location and proceed with downloading the video!
