About two years ago, Mozilla presented the Firefox Quantum, a new "incarnation" of your browser designed to bring it back to its former speed and make it compete again with Google Chrome. The endeavor was a relative success and subsequent versions of the browser were able to hold the bar, with quite satisfactory performance.
Only the change brought a problem: energy consumption. Since the release of the Quantum version, Firefox has started to require much more of the battery of computers, especially in macOS. So good, then, that the browser development team is aware of this and seems to have cracked the puzzle to make it more energetically speaking without giving up on performance.
The good news is in the Firefox Nightly, the browser (alpha) trial version that is updated every night and can be downloaded by any user. The latest software update brings significant improvements in the power used to load pages and, therefore, in the browser requirement of the portable device battery. The quantifiable improvement: According to developer Henrik Skupin, because of it future versions of Firefox may consume up to 3x less energy.
The person responsible for all this change from water to wine has a name: Core Animation. O framework Apple is now responsible for rendering web pages in the new Firefox test version, significantly optimizing power consumption in the process. Data shared by Mozilla shows that previously accessing a page in Firefox used between 21W and 30W of power, requiring an additional 10W or 15W for the GPU. With Core Animation, loading each page requires between 7W and 8W, with an extra 0.2W for the GPU.
It is not known exactly when the improvements will arrive in the final release of Firefox for macOS, but we may have some good news with the arrival of browser version 70, which should be released in the coming weeks. Meanwhile
Mozilla today launched the verse 69 from Firefox for macOS still without the deep energy improvements, but with some interesting news. To begin with, here is where the new browser policy of blocking really applies trackers of advertisers by default.
As we explained in this article, blocking was once restricted to private browsing, but is now expanding to the entire browser experience even for veteran users. When the Enhanced Tracking Protection (ETP, name given to resource) is active, the user will see a purple shield in the address bar; By default, the "basic" mode is active, but it is possible to activate a "strict" mode of protection that also blocks fingerprinting. You can also, if you wish, disable the feature as a whole.
Firefox 69 also brings another step toward the death of Adobe flash, which almost no one knew is still alive. Now, the user should enable the use of the plugin manually each time he visits a site that uses it, but there is no longer a list of allowed sites that load the old technology automatically.
In other news, the blocker of autoplay It also works now with videos without sound. And Mozilla claims that on Macs with multiple graphics cards (such as 15 ″ MacBooks Pro), the browser will use the lowest power GPU by default, saving battery power. Finally, Finder can now display the progress of downloads being made in the browser.
Firefox 69 can now be obtained from the Mozilla website or by simply restarting your browser.
