Firefox 54 Improves Multi-Process Architecture

Firefox has improved its multi-process architecture in order to isolate more content while keeping memory use low:

Firefox 54 launched with a more advanced multi-process architecture than the one we saw implemented in Firefox 48 last year. The improved architecture raises the number of processes enabled by default from two to five, which Mozilla argues is a "just right" compromise between low memory usage on one side and performance and security on the other.

[...] Switching to a simpler extension model allows Firefox to enable multiple processes and also isolate them in sandboxes. Mozilla previously enabled only two processes, one for the UI and one for content, last year, in Firefox 48. This ensured that the browser wouldn't hang as much due to web pages affecting the performance of the browser interface. It also brought partial sandboxing by keeping the content isolated from the browser (as much as possible).

Mozilla is now taking it to the next level by implementing one process for the browser interface and four for content. Why four? The organization believes that this is the "just right" amount of processes to have for the majority of users, and also in terms of optimizing memory usage.

[...] Mozilla ran its own memory usage benchmarks, which showed significant memory usage reduction compared to Chrome:

  • Windows 10 — Chrome used 1.77X memory as Firefox (64-bit), and 2.44X as Firefox (32-bit)
  • macOS — Chrome used 1.36X memory as Firefox (64-bit)
  • Linux — Chrome used 1.42X memory as Firefox (64-bit)

    Try it again. My experience with online chat help (not with dell) is they will give conflicting info.

    Nowadays I use youtube to figure out stuff like that: https://www.youtube.com/watch?v=2kbHZjWZlj4 [youtube.com]

    I won't rely on standard "support" since too many of them don't know what they are talking about. Some may lie or post unrelated/useless answers to have their stats look nice.

    I might trust enterprise level support more, might have no choice if it's for stuff I can't find youtube videos for.

    The other advantage of the youtube video is you can see how difficult it is and decide to buy a new device instead... :)

      I wouldn't totally trust Youtube either. Not the fault of the guys who post the videos on there, but Dell is (or at least was) pretty notorious for changing the internals of systems without any notice or change in model number. So while you might find some guy posting pictures of the internals, you could open up your computer with the same model number and specs and find a totally different board, with different chipsets, numbers of slots, etc.

        That's why the Youtube method is better than relying on the claims of some outsourced support person- if you pay attention you'd notice the stuff is different. So if you're paranoid may wish to open up the stuff to compare before buying the upgrade. Whereas you're unlikely to get that level of help or info from typical support.
