Mozilla and Google are developing iOS browsers that use their respective engines in place of WebKit in anticipation of a change to Apple’s browser policies.
Code for the iOS version of Firefox, starting with Mozilla, makes use of the Gecko layout engine. Software developers for Mozilla have posted about a “proper Gecko Firefox on iOS.” Microsoft’s decision to replace its EdgeHTML browser engine with Chromium was once criticized by Mozilla. Mozilla claimed that action reduced market competition and gave Google an excessive amount of power.
The business is also preparing a non-WebKit browser over in the Googleverse. The project is still considered experimental, and Google “continues to abide by Apple’s policies,” according to code commits.
