Since a week or two now, whenever I open a github issue page the tab or the browser freezes, depending whether I have e10s enabled or not. It affects all channels, including stable.
You have to be logged in to github for this issue to present itself.
When I have e10s on I get multiple "this page is slowing down firefox" alerts an may last more than a minute. With e10s off the whole browser freezes, but for a much shorter time.
I isolated this issue to this script. After disabling it the pages load normally.
