User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID: 20160205004003 Steps to reproduce: Open an animated .gif Image and scroll the entire image out of the viewport margins After some time (Depending on .gif Size, frame number and duration) scroll it back into the viewport Actual results: Process hangs for several seconds up to several minutes depending on the time the .gif has been outside of the viewport Expected results: .gif re-entering the viewport should start playing either from the last frame in viewport or from the first frame of the animation
Could you attach a simple testcase with a html page including a GIF, please.

A very barebone test case, scroll down to load the gif and then scroll back up top, wait some time (I would suggest more than an hour) and then scroll it back into view. Epilepsy Warning

Hi PParrot, I have tested your issue on latest Nightly (47.0a1) build, latest Aurora (46.0a2) build and could not reproduce it. I have ran your provided test case and followed your steps but after an hour when I scrolled back into the viewport, the ".gif" started playing again. Firefox: 47.0a1, Build ID: 20160208030244 User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0 Firefox: 46.0a2, Build ID: 20160209004008 User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0 Can you please test this on the latest Nightly (47.0a1, https://nightly.mozilla.org/) and tell me if this still reproduces for you ? When doing this please use a new fresh Firefox profile, maybe also in safe mode (https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems). Thanks, Cosmin.
