In Opera browser, you can unhide the menu bar using the menu options.
To display the Menu bar, click the drop down arrow available next to Menu. Scroll down and select Show Menu Bar from the list of available menus.
After selecting the Menu bar option, then menu bar would appear at the top of the browser as shown above.
Way outdated and is useless.
This might have worked 8 years ago. But in November 2019, using Version:65.0.3467.48, this information is not applicable. “Show Menu Bar” is not a selection in the dropdown main menu they use now.
Do you have an updated version of how to show the menu bar?
Thank you.
