Firefox Focus is switching from Chrome WebView to the Gecko engine
There are a number of components to the web browser with the parts we interact with simply being the user interface for it. There’s a lot of stuff going on under the hood and how a browser performs can depend largely on which engine it’s using. Mozilla introduced Firefox Focus as a separate web browser that focused on privacy by blocking ads and not storing our browsing history. Right now, the stable version of Firefox Focus uses the Google Chrome-based WebView, but all nightly versions of the app are now switching to the Gecko engine.
The switch from Chrome WebView to Gecko doesn’t seem to be performance related. Instead, the reason has to do with the core goal of FireFox Focus in the first place: privacy. Mozilla has found a reason to believe that the Chrome WebView engine can leak someone’s data. So in the spirit of maintaining data privacy, the team behind Firefox Focus has decided to switch to the Gecko engine.
This transition will also allow Firefox Focus to do more than the browser was able to do with Chrome WebView. Specifically, Firefox Focus can now implement a better version of its private browsing feature while also blocking trackers from gathering information about you. This is something that wasn’t possible with Chrome WebView since it’s not something that Google has ever allowed. This new engine is currently only available on the nightly version of Firefox Focus with new builds being published every 24 hours.
To participate in the alpha test you will first need to join the Google Group for this nightly branch and then you can opt in to join the test via the Play Store. Then, you can download the app from the Play Store.
