Firefox 48 adds multi-process support, but only for some

  1. Version 48 of Mozilla’s popular Firefox web browser has found its way to the stable channel for both desktop and Android.

    We’ve all been there. You’re surfing along with a dozen or so tabs open and suddenly, something goes awry in one tab and wipes out everything. Starting with Firefox 48, Mozilla hopes to mitigate the damage through a technique called multi-process (also known as Electrolysis or e10s). Confused?

    In layman’s terms, the new feature – which is only being rolled out to some desktop users for now – separates web content from Firefox’s UI processes. When a site is consuming a large amount of your computer’s processing power, your tabs, buttons and menus shouldn’t freeze.

    Nick Nguyen, Vice President of Firefox Product at Mozilla, said they’re starting the rollout with just one percent and will ramp up to nearly half of the release if things go smoothly.

    To see if your browser is among the lucky ones, simply type “about:support” into the URL bar. If the feature is active, you’ll see “1/1 (Enabled by default)” under the Multiprocess Windows line item.

    Elsewhere, Mozilla has made changes to its Awesome bar. Specifically, queries will surface a wider range of suggestions (and the suggestions will physically span further across the screen for improved readability). You may also notice changes to the Discovery Pane in the form of a new design which Nguyen says will simplify the installation of featured add-ons down to just a single click.

    Firefox 48 is available as of writing for Windows, Mac and Linux. If your browser doesn’t auto-update or you don’t already have Firefox, you can grab your copy right here.

    I really want them to improve the performance of "awesome bar". Compared to the URL bar from chrome it's just slow. I always end up searching for letters in google instead of going to the website that should have it's url autocompleted.

    Where can I enable or see this awesome bar? I don't seem to have it either.
    Also is there a way to manually enable the multiprocess thing as I seem not to be one of the "lucky" ones.

    What I really want to see them improve is performance. Chrome in general is still faster. Even my with 30 tabs opened, along with extension plugins installed, chromes noticeably more faster than a fresh stock firefox.

    What I don't like about firefox is that it starts to lag horribly after a while... and I have to restart it.

    Setting browser.tabs.remote.autostart to true in about:config did the trick for me.

    Did that on mine, says disabled by add-ons. Disabled add-ons, still no go.
    Oh well, maybe in a future release...

    Forget to mention that I restarted FF after changing the setting. Also, I'm on Linux, might be different on other platforms.

    Isn't Chrome's default to run each tab in a separate process? That is what I've seen, and I've never had on crap site crash Chrome, only the tab. Firefox only does one process for everything, so yeah if one goes it brings down the whole ship. This should have been fixed a long, long time ago and I'm sure it is a contributing reason for it falling down the browser popularity ladder. I try Firefox every once in awhile, and every time I have the same problems. I just have terrible luck with it, it crashes somewhat often and is often slow. Maybe this change will finally bring them back up the ladder? I'll have to try it again...
