Install Chrome Extensions in Opera and Conversely

If you’re an avid Opera user but at the same time you like Chrome extensions – with the latest versions of these browsers, you can have the best of both worlds! Opera Next is great so far! Vimium, LastPass, Adblock, and RSS Subscription Extension (with the Feedly tweak) from the Chrome extensions store, and you can enjoy a snappy, beautiful, and very useable browser! 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).

Installing Chrome extensions in Opera 15 is easy: First, install the Chrome Extension Installer for Opera Next 15. Then go to the Chrome Web Store and install whatever you want. The Web Store won’t complain that you need a supported browser or anything—it’ll just work. The extension you want will download and install, and it’ll work normally.

To install Opera Next extensions in Chrome, you’ll need to download the Opera extension file, rename it, and install it in Chrome:

• First, make sure Opera Next is installed.
• Then, go to the new Opera add-ons page. You have to visit this specific page in Opera Next—this is important because the page auto-detects which version you’re using, and will only show you compatible extensions for that version of Opera. To get the extensions that’ll also work in Chrome, you have to use Opera 15 to browse the store..
• When you find one, instead of clicking “Add to Opera,” right-click the button and select “Save Linked Content As…” and save the .nex extension file somewhere you can get to it.
• Grab the .nex file and rename it to end in .crx.
• Open Chrome, and drag and drop the .crx file onto Chrome. You’ll be prompted to review the permissions before installing it, but that should be all.

That’s all there is to it. The process works pretty quickly, and the downside of going from Opera to Chrome is that you need both installed. Still, it’s worth noting that the Opera add-ons page is pretty sparse when it comes to Opera Next add-ons right now, mostly because Opera 15 is still in active development. It’ll fill up pretty quickly, and with time you’ll be able to find extensions there you may not find for Chrome. Even so, right now this is a bit more useful for getting your favorite Chrome extensions into Opera if you want to give the new engine a whirl.
