Editing Gecko (software) (section)

===Background===
In 2012, Mozilla began the experimental [[Servo (software)|Servo project]], which is an engine designed from scratch with the goals of improving [[Parallel computing|concurrency and parallelism]] while also reducing [[memory safety]] vulnerabilities.  Servo is written in the [[Rust (programming language)|Rust programming language]], also created by Mozilla, which is designed to generate [[compiler|compiled]] code with better memory safety, concurrency, and parallelism than compiled C++ code.<ref name="Servo_paper"/>

As of April 2016, Servo needed at least several years of development to become a full-featured browser engine,<ref>{{cite web|url=https://github.com/servo/servo/wiki/Remaining-work/0e3b111807c2ed4c11f36d6bd47dda6dfa02d502|title=Servo remaining work|website=GitHub |access-date=2017-02-17}}</ref> hence the decision to start the Quantum project to bring stable portions of Servo into Firefox. Mozilla laid off all Servo developers in August 2020.<ref>{{Cite web |title=Mozilla lays off 250 employees while it refocuses on commercial products |url=https://www.zdnet.com/article/mozilla-lays-off-250-employees-while-it-refocuses-on-commercial-products/ |access-date=2022-06-14 |website=ZDNet |language=en}}</ref>
