4. And click download and run the file, after installing the flash player, reopen or restart the browser.

Note: Installing Flash once by visiting adobe site in Vivaldi or Opera is enough, you don’t need to install two times for each browser.

Using Chrome’s Flash in Opera /Vivaldi

if you’ve Google Chrome installed on your computer, the chromium-based Opera or Vivaldi picks up the Flash of it and uses to load that plugin content in respective browsers.

If you’re using either of these browsers, and if you’ve already installed Chrome, then you don’t need to install Flash in the first place, provided you need to be using the same architectures between Chrome and Opera/ Vivaldi browsers. Means, if you’ve Chrome 32-bit installed, you should be using the 32-bit version of Vivaldi or Opera (x86) for the browser in question to pick up and use Chrome’s flash.

Note: BTW, don’t forget to check or first ensure Flash is enabled after install by visiting Vivaldi://plugins or Opera://plugins pages.
