Integrating Capital One Shopping with Opera would greatly enhance the browsing experience by providing users with valuable money-saving features. This addition would be highly appreciated by Opera users.

@pinheadlucas Right now the Opera website doesn't let me update the extension, because it says the opus file type is a an invalid type (IIRC I tried wav and ogg vorbis formats too, which were rejected as well). The Firefox add-ons site and the Chrome WebStore do not impose such a restriction. I believe the Opera developers merely forgot to whitelist this benign file type.
I reported the issue to Opera, of course, as DNAWIZ-73448.

I was waiting for a response and fix from Opera (which I guess should be as easy as adding opus to some list), but so far nothing. Since it has been about 20 days since I reported the issue and nothing has happened, I will now add a work-around where I just remove the "play sounds" feature completely from the Opera version. This will take some time, so it will be ready maybe this weekend.

Thanks. You make things so much easier and more convenient. Thanks a lot! Have a great time!
