How to Install Chrome Extensions in Opera

The actual process of installing Chrome extensions in Opera is surprisingly easy. It requires a little bit of setting up though. For the sake of this example, we’ll use the Google Cast extension, to make maximum use of your Chromecast 8 Creative Uses for Google's Chromecast We've come up with 8 unique uses for Google's Chromecast. Read on to find out just how you can make even more use of your Chromecast. Read More .

  1. First and foremost, download Opera, of course.
  2. Next, add and install the Download Chrome Extension from the Opera add-ons gallery.
  3. Go to Chrome’s Google Cast extension page [No Longer Available].
  4. Click the red Download Chrome Extension icon in the URL bar.
  5. Click the Add to Opera button.
  6. A toolbar will drop down, with the message, “This extension was disabled because it is from an unknown source. Go to the extensions manager to enable it.” Click the Go button.
  7. You’ll be transported to Opera’s Extensions page, which can also be visited by going to View > Show Extensions.
  8. Click Install in the Google Cast extension, and click Install again when Opera asks you to confirm you want to add this extension from an unknown source.

And just like that, the Google Cast extension will be added to Opera! You are now ready to use it just like how you would operate it in Chrome.

What Opera Doesn’t Support

However, while you can install any Chrome extension, that doesn’t mean every Chrome extension will work in Opera. For example, the Picture in Picture Viewer extension [No Longer Available] that lets you view YouTube videos in a floating panel depends on Chrome’s Panels feature, which Opera doesn’t support. So while you can install the extension in Opera, you can’t actually use it!



Opera also does not work with Chrome apps. It’s restricted only to extensions. Unfortunately, this means you miss out on some nifty tools. For example, Opera users can’t use Videostream, the easiest way to cast media from your computer to Chromecast or Android boxes How to Cast Local Media From Your Mac to Chromecast Here's all you need to know on how to stream to Chromecast from your Mac, whether you're casting videos, music, or photos.

    Switched to Opera a month ago and have loved it. Unfortunately the Chromecast extension has been discontinued w/ its functionality being built into Chrome, so there is no extension to add to Opera now :/

    Firefox is the only interface that works for me, even after Mozilla (somewhat) screwed it up! I prefer the old Firefox interface, with the status-cum-addon bar at the bottom. So I am pissed at Mozilla for removing it (instead of simply making it optional), but thankfully Firefox is flexible enough to allow an extension-based status bar. It's not perfect because some addons refuse to be moved to the new status bar, but it's still better than having them occupy more than half of the main toolbar.

    I installed the chromecast app using this guide and it has installed fine. However, whenever I click on the extension in the toolbar, my chromecast doesn't show up.

    Does anyone have advice on how to get this to work?

    I recently switched from Firefox to Vivaldi and I love it. The only thing I really miss is the ability to tag bookmarks so I can find them again by referencing the tag.

    It's pretty easy to use despite being "advanced". It also does a number of basic things better like automatically giving you a print preview. It also has a ton of tab management features built-in.

    Some of the developers came from Opera, so there are similarities.

    I have installed a couple of add-ons from Chrome which work, but haven't tried many yet.

    The main reason I switched is that since around Firefox 3, they have been consistently taking features I loved and removing or breaking them. I have a bunch of add-ons installed just to undo damage by the developers.

    OPERA15+ Is A CHROME Clone.

    A - Most CHROME Clones Extensions Can Be Installed Into Other CHROME Clones - Just Get The Intended Extension On File And Rename It .CRX, .NEX, Or Whatever,

    B - There Is An Extension For FF That Allows The CHROME WEB STORE Extensions To Install Into FF, But In My Experience:

    B1 - Most Extensions Do Not Install,

    B2 - I Successfully Installed Only 1 Extension, But I Could Not Figure Out How To Use It, So True Success Is Still Away.

    I recently switched from Chrome to Opera when the latter announced its "VPN" feature, so I installed Developer version 38. In version 39 VPN can only be activated in private mode, which I am not happy with, but have since installed extension DotVPN. Version 39 also features the power saving mode, which, although there are some Opera measured stats but no independent stats, does seem to save battery life.
    Overall I am happy with Opera, although I will consider also returning to Firefox when it allows installing Chrome extensions.

      I noticed the change from normal windows to private windows as a requirement for the VPN while on vacation last week. I was on hotel wifi at the time, so wondered if it was related to that scenario, but now I'm disappointed to see that it's not. I'm sure Opera is considering the safety of private windows versus normal ones, but hopefully some enterprising developer will produce an extension to work around this hindrance.

      I've been switched over to Opera from Chrome for about three weeks now, and it has been a 95% trouble-free transition. I loved Opera years ago for its forward-thinking innovations, and now I love it all over again. It feels fresher than Chrome, and the only minor improvement I could suggest would be to allow me to reorder my extension icons how I want them. :)

        Yeah, the switch to "incognito-only for VPN" happened in the last week I think. Disappointing, but let's hope they'll bring it back :)

        Pro tip: Get the Surfeasy extension, since that's Opera's VPN anyway.

          I'll check out that extension. Mihir. I'd actually decided to try Opera again just because of The VPN, so this was more than a little irritating. Thanks. :)
