Amazon and other video services need to acknowledge Vivaldi
Here is a example of a response I always get from amazon
Bobby: I've checked and see that Prime videos are compatible only with the following browsers.
M42 or newer
Version 3.0 or above
- Internet Explorer
Version 11 or newer
- Microsoft Edge
Version 31 or newer
Version 5.0 or above
All the above browsers run on HTML5 except for Safari and Firefox.
Safari and Firefox use Silverlight plugin to stream Prime videos
You should be able to use if your new browser has and supports these plugins
Me: can you fill a request because Vivaldi is technically based on chrome engine so it should work
Bobby: Surely, I'll pass your comment to our Amazon development team. So that they will work on this web browser to make this as better in future.
Thanks for your information.
Bobby: It is also highly recommend when using HTM5 browser to update Widevine Content Decryption Module to it's latest version
