Opera has a ton of special features to try and distinguish their browser from others. The latest feature to be added to Opera 68 for desktop is built-in access to Instagram. Clicking a button on the sidebar of the browser will give the user fast access to your feed, Stories, and direct message.
It’s not like these features aren’t available on other browsers, but Opera is hoping that the convenience their Instagram built-in feature offers will sway your perception. I guess this will come on handy for those who use constantly need to check their Instagram profiles for business or person needs.
