Before I bought my Android, I heard that Firefox was its default browser. Upon noticing that this is not the case, I had assumed that the Internet browser on the Android was Google Chrome, but I just installed that today. Was Firefox ever the Android's default browser, and what is it now?
Firefox was never the default Android browser. The actual default browser is based on the open-source WebKit engine, which also powers the Safari browser on desktops, laptops and Apple's iOS-based mobile devices.
In the other hand, Chrome is based in Chromium and offers more options and performance than the stock browser.
