    How to Enable or Disable Tab Warming in Firefox in Windows


    Firefox usually does a good job most of the time when it comes to tab switching performance, some sites have noticeable delays between activing the tab and Firefox switching to it.

    Firefox 61.0 comes with a new feature called Tab Warming that can give speedier response times when switching between tabs because Firefox is preemptively loading tabs when youíre hovering over them.

    Tab Warming is enabled by default in Firefox.

    This tutorial will show you how to enable or disable Tab Warming to preemptively load tabs when you hover over them in Firefox for your account in Windows 7, Windows 8, and Windows 10.



    Here's How:

    1. Open Firefox.

    2. Type about:config into the address bar, press Enter, and click/tap on the I accept the risk button. (see screenshot below)

    3. Copy and paste browser.tabs.remote.warmup.enabled into the search box, and press Enter. (see screenshots below step 4)

    4. Double click/tap on the browser.tabs.remote.warmup.enabled setting to change its value to true (enable - default) or false (disable) for what you want. (see screenshots below)

    5. You can now close this about:config tab if you like.


    That's it,
    Shawn

    Are you supposed to notice a difference?
    I updated to FF 61.0 and it was set to enable, but tabs still seem to render after I click tab, not hovering.
    I can't notice any difference enabled or disabled, Though I do use Ublock and most pages load fast.

    The link below is a test site to see if you may notice any difference.

    There are certain sites, however, that we canít render and upload layers for as quickly. These are the sites that I think warming will help with.

    Hereís an example of such a site

    The above link is using SVGs and CSS to do an animation. Unfortunately, on my MBP, if I have this open in a background tab in Firefox right now, and switch to it, thereís an appreciable delay between clicking that tab and it finally being presented to me.

    Thanks, I tried the wavey site and get split second till it renders with it set enabled or disabled (restarted FF between settings).
    I'll just leave it enabled, haven't seen any downside so far.
