User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0 Build ID: 20160614030210 Steps to reproduce: View GIFs on tumblr.com. Examples that render incorrectly: 1: https://66.media.tumblr.com/de406572480fd64f07d2d3754f3907fb/tumblr_o8q4hc37Cc1rjyrfgo1_540.gif 2: https://67.media.tumblr.com/211eb4c33b56cf73b002de3d6816cd21/tumblr_o8pbyqwYqu1rjyrfgo5_400.gif 3: https://67.media.tumblr.com/e37fa293a740003c99ae8e597e6cc9ed/tumblr_o82c95Y32n1uc3fxyo2_500.gif Actual results: The GIFs loop prematurely, before reaching the final frame. I have tried restarting with addons disabled, emptying cache, and downloading the images then loading them locally but they still do not display properly in Firefox. In Chrome (Windows) and on iOS Tumblr app, the GIFs render correctly. In Firefox: Example 1 loops around frame 36, it should get to frame 52. Example 2 loops around frame 42, it should get to frame 88. Example 3 loops at frame 2, it should get to frame 33. Expected results: Firefox should wait until reaching the final frame of the animation before looping.
