Firefox 16 Now Faster With Incremental Garbage Collection

Mozilla's Firefox browser hit version 16 today, bringing with it a new feature called incremental garbage collection. Mozilla said that it has worked on this major feature for over a year and that it will improve performance in responsiveness as well as smoothness.

Firefox's garbage collection collects memory that JavaScript programs are no longer using. In earlier versions of Firefox, the garbage collection function would run for hundreds of milliseconds, essentially freezing the browser. Incremental garbage collection divides the work into smaller chunks.

"Rather than do a 500 millisecond garbage collection, an incremental collector might divide the work into fifty slices, each taking 10ms to complete. In between the slices, Firefox is free to respond to mouse clicks and draw animations," Mozilla wrote in a blog.

    meanwhile the latest version of Chrome is annoyingly unstable! Hopefully the update that was pushed through last night will help things, because otherwise I am seriously considering moving back to FF.

    A more optimized version of Firefox is Palemoon. I am using that. It has compiler optimizations to target new processor and CPU instructions. Also, the program is Profile-guided-optimised.
    Think of Palemoon as Overclocked Firefox. :)

    But when will they make scrolling work (by trackpad or arrow keys) while watching a youtube video or other flash? The flash captures the controls, breaking the scroll. Can't believe I'm the only one with that problem?

    If I met that girl, I would ask her.
