I am no legal expert, and this is a tech publication. Hence, I am not going into the legalities of this case, but you can scan the internet for details regarding the case, Google’s response, its current status etc.

Browser Engines: The Landscape

Mozilla notes the decline in browser engines. What used to be five engines in 2013 is now down to three: Apple’s WebKit, Google’s Blink, and Mozilla’s Gecko. This is primarily due to the immense expense and expertise required to maintain these engines.

Microsoft, a technology behemoth, also abolished its Trident browser engine in favor of Google’s Blink for its Edge browser.

Firefox: Impact

Mozilla notes the small footprint its browser, along with other independent browsers, occupies in US search queries. However, its impact significantly outweighs its proportion by providing an alternative choice to consumers, along with a strong focus on protecting privacy.

Mozilla also emphasized that the choice of a search engine ultimately depends on customer preference. Firefox chose Yahoo as its default search engine in the US from 2014 to 2017. However, this decision proved unsuccessful. Hence, it moved back to Google as its default engine in 2017, while ensuring non-exclusivity to maintain independence in promoting a range of engines.

Today, Firefox users in the U.S. can choose between Google, Bing, DuckDuckGo, Amazon, eBay and Wikipedia directly in the address bar. They can easily add other search engines and they can also benefit from Mozilla innovations, like Firefox Suggest.

Revenue

Google is a major source of revenue for many browser vendors who offer it as their default search engine. This revenue allows Mozilla and other vendors not just to survive, but also gives them the ability to innovate.

Mozilla birthed major technological ecosystems, such as Rust and Let’s Encrypt, which play a critical role in our technological landscape today. These technologies continue to develop outside of Mozilla today.

The ramifications of Google being forced to terminate such agreements could be significantly detrimental to the survival of smaller players like Mozilla and its Gecko engine.

Google is expected to present its arguments next month. Time will tell whether these payments can continue in the future.
