If you have been using Opera and Google Chrome simultaneously you don’t have to miss the extensions and apps that both these browsers use. Google has come up with a new Webkit-based engine for Google Chrome and the same engine is used in Opera Next. The greatest advantage of having the same rendering engine is that the extensions used by both the browsers can be interchanged; that is, you can install Opera extensions in Google Chrome and vice versa.
Why would you install Opera extensions in Google Chrome
For the similar reason why you seek the same apps when using different operating systems. You get used to certain functionalities and you would like them to be available wherever you work. Browsers these days have become complete environments in themselves and you find yourself doing technically everything from within your browser. It also means running some extensions and apps that you would otherwise use as standalone software applications.
Here is how you can install Opera extensions in Google Chrome (presuming you have both the browsers installed on your machine):
As mentioned above, both Google Chrome (preferably 28) and Opera Next must be installed on your computer.
Launch Opera and go to the add-ons page. It auto detects which version of Opera you are running and displays compatible extensions accordingly. In order to be able to install Opera extensions in Google Chrome you must be running Opera 15 while browsing the store.
Find the extension you want to install in Google Chrome but don’t “Add to Opera”, instead right-click and then from within context menu, click “Save Linked Content As…” It will let you save the extension file with .nex on your computer.
Access the .nex file on your computer and change its extension as .crx.
Now launch Google Chrome and drag-and-drop this .crx file onto it. After granting the permission to install the file, the extension will be added to it.
Do all the extensions work? Not necessarily but most do. The only downside is both Opera Next and Google Chrome must be installed on your computer in order to exchange extensions.
