Chrome Extensions & Opera Extension can be install/use in both Chrome and Opera

The latest versions of Chrome and Opera have a lot in common. Google has been hard at work on a new Webkit-based engine that will power them both, and one pleasant side effect is that it's now really easy to install Chrome extensions on Opera, and Opera extensions in Chrome. Here's how to do it.

For this to work, you'll need Opera Next 15 or higher, and Chrome 28 or higher (this also works in dev and beta builds, along with Canary).

Install Chrome Extensions in Opera

To gain access to Chrome extensions from Opera, simply install the Download Chrome Extension in Opera and then visit the Chrome Store and choose the extensions you want to install. You will find that the blue “Add to Chrome” button is now replaced with a red “Add to Opera” button. Click on it to install the Chrome extension in Opera.

Note, that you can only install extensions and not Chrome apps.

Install Opera Extensions in Chrome

Installing Opera extensions in Chrome is also possible, it just requires a little more work to be done.
Start by visiting the page for the Opera extension that you want to install in Chrome in the Opera browser. Now right click over the green “Add to Opera” button and choose the option to save the linked content. This will download the Opera extension as a file having the extension .NEX.




Change the file extension from .NEX to .CRX, the format supported by Chrome.

After that, open Chrome and access the Chrome Extensions page (chrome://extensions) and drag and drop the file you downloaded and renamed. This will install the extension.
