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 you’re 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.
