* Firefox 83 is in the Nightly channel and over the last week it received about 350 changes. The most intersting change this week was [https://bugzilla.mozilla.org/show_bug.cgi?id=1666417 enabling Warp]. Warp is the name of a significant update to SpiderMonkey, our JavaScript Engine. More precisely, Warp is the project to replace the frontend of our optimizing JIT (IonBuilder) and the engine's Type Inference mechanism with a new MIR builder based on compiling CacheIR to MIR. Warp will let us improve security, performance, memory usage and maintainability of the whole engine. Turning on Warp for Nightly has already shown a large improvement for web performance there. For example, loading Google Docs is about 20% faster with Warp enabled. If you're on Nightly, you can find the [https://bugzilla.mozilla.org/show_bug.cgi?id=1665415 on/off switch] for Warp in the Experimental Features section of Preferences/Options.
