That sounds frustrating. If you can't scroll on some websites, it might be worth checking if you’re using any tracker blockers or cookie consent extensions. Sometimes, these can interfere with website functionality. I’ve noticed that ad or tracker blockers (including Opera’s built-in one) can mess with cookie consent screens. Try temporarily disabling the blocker, handle the cookie consent, and then re-enable it.

Also, some sites are clever enough to detect ad blockers and display warnings, but these warnings can get blocked too, which might make the page seem unresponsive. Clear your browser’s cache and cookies, or restart it to see if that helps. If the problem persists, make sure your browser is up to date or try using a different one.

And the second question is why Opera takes more internet data than other browsers.
Is there any helpful content or videos on how to use opera effectively and I think you have

Some websites showing errors in Opera might be due to HTTP compatibility issues. As for data usage, Opera may use more data because of its built-in features and services.
