Better TweetDeck was available on https://addons.opera.com, but the Opera add-ons team's review times have been very complicated to deal with, so the Opera version always was days if not weeks late compared to the Chrome/Firefox one.

Fortunately, there's a "better" way. It's a workaround, it's not ideal, but at least you'll get updates at the same time as Chrome and Firefox users!

Follow those steps:

• Open Opera
• Go find Better TweetDeck on the Chrome Web Store
• Install Better TweetDeck by clicking "Add to Chrome"
• Confirm the install when Opera asks you to
• You're all set! Enjoy 🎊
