In terms of head to head utility, { -brand-name-opera } and { -brand-name-firefox } are close competitors. { -brand-name-opera } may have an advantage in one aspect with its compatibility with and access to { -brand-name-chrome }’s huge extension library. But one significant factor to consider is the fact that { -brand-name-opera }, because it’s built on { -brand-name-chromium }, is a processor-hungry browser with its RAM consumption comparable to { -brand-name-chrome }, which is known for its high CPU usage.
就实用性来说，{ -brand-name-opera } 和 { -brand-name-firefox } 不相上下。但 { -brand-name-opera } 可能在扩展方面有优势，因为它兼容于 { -brand-name-chrome } 庞大的扩展库且可以正常访问。但有一点需要考虑的重要因素是，{ -brand-name-opera } 是基于 { -brand-name-chromium } 而构建的，这就意味着它是一款 CPU 密集型浏览器，其内存消耗量与 { -brand-name-chrome } 相当，而 { -brand-name-chrome } 以 CPU 使用率高而闻名。
