Seriously its like Opera is not done with Microsoft ranting yet as the come again for microsoft based on Browser Batter life. 

In the post, Opera said that Microsoft had not revealed its full test methodology, and so they were unable to run the same tests. This prompted Opera to run and publish their own tests which found Opera to come out on top.

Opera says that the Opera Developer (39.0.2248.0) with native ad blocker and power saver enabled is able to run 22% longer than Microsoft Edge (25.10586.0.0) on a laptop running Windows 10, 64-bit, and 35% longer than the latest version of Google Chrome (51.0.2704.103).

Opera also detailed its methodology in the post challenging Microsoft to better. “If Microsoft really wants to prove that its browser performs better than others (in any regard), the company should be transparent about its methodology so that others can replicate it.” says Błażej Kaźmierczak, Director of Software development at Opera.

Well, what the fuck is chrome waiting for? Am really enjoying this their beef for my sake. Jah Bless ya'all Hustle
