Some things I've been looking forward to: > Easier performance management: The new Task Manager page found at about:performance lets you see how much energy each open tab consumes and provides access to close tabs to conserve power > Improved performance for Mac and Linux users, by enabling link time optimization (Clang LTO). (Clang LTO was enabled for Windows users in Firefox 63.) Release Notes: https://www.mozilla.org/en-US/firefox/64.0/releasenotes/ https://www.mozilla.org/en-US/firefox/64.0/releasenotes/

> Easier performance management: The new Task Manager page found at about:performance lets you see how much energy each open tab consumes and provides access to close tabs to conserve power This is pretty neat, now I'm wondering why the webex extension is having "Medium" impact when it should be doing nothing.

  Because it's webex ... sigh ... At least it's not Google Hangouts. That crap platform will kill any laptop battery in ~30-45 min flat and make it seem like you're rendering some 8K video.

  I'm sure those who build it themselves could have enabled this in earlier versions already, and I assume this means the pre-built binaries now enable this.

  The binary should ship that way unless your distro decided otherwise. You can easily check by going to about:buildconfig and seeing which compiler was used.

about:performance is pretty nice. Strangely it doesn't show tabs that aren't top level in Tree View Tabs.

Are there any notes on what the number means? Release notes does not mention the units or meaning of the number next to the amount of performance hit.
