Firefox Hello provides more value to Firefox users by making it easier to communicate with your friends and family who might not have the same video chat service, software or hardware as you. It’s free to make voice and video calls
Slimmer and faster JavaScript strings in Firefox
Since Brendan Eich wrote the first SpiderMonkey version in 1995, there have been many, many changes to its internal string representation. New string types like inline strings (more on this below) and ropes were added to save memory and improve performance, but the character representation never changed: string characters were always stored as a sequence of UTF-16 code units. The past two months I
The Baseline Compiler Has Landed
This wednesday we landed the baseline compiler on Firefox nightly. After six months of work from start to finish, we are finally able to merge the fruits of our toils into the main release stream. What Is The Baseline Compiler? Baseline (no, there is no *Monkey codename for this one) is IonMonkey’s new warm-up compiler.

asm.js in Firefox Nightly | Luke Wagner's Blog
I’m happy to announce that OdinMonkey, an asm.js optimization module for Firefox’s JavaScript engine, is now in Nightly builds and will ship with Firefox 22 in June. What is asm.js? Why are we doing it, and how are we getting to within 2x of native performance? This post won’t be able to go into too much detail since we’re hard at work preparing for Mozilla’s upcoming GDC session, which you should
DMD – Nicholas Nethercote
I recently landed a new version of DMD on mozilla-central. DMD is a tool helps us understand and thus reduce Firefox’s memory consumption. But in order to understand DMD, you first have to understand about:memory. about:memory The MemShrink project started about 18 months ago, and it has been very successful in reducing Firefox’s memory consumption. about:memory is MemShrink’s not-so-secret wea
IonMonkey in Firefox 18
Today we enabled IonMonkey, our newest JavaScript JIT, in Firefox 18. IonMonkey is a huge step forward for our JavaScript performance and our compiler architecture. But also, it’s been a highly focused, year-long project on behalf of the IonMonkey team, and we’re super excited to see it land. SpiderMonkey has a storied history of just-in-time compilers. Throughout all of them, however, we’ve been

How to Compare the Memory Efficiency of Web Browsers – Nicholas Nethercote
TL;DR: Cross-browser comparisons of memory consumption should be avoided. If you want to evaluate how efficiently browsers use memory, you should do cross-browser comparisons of performance across several machines featuring a range of memory configurations. Cross-browser Memory Comparisons are Bad Various tech sites periodically compare the performance of browsers. These often involve some cross
