>>> My Info: Win7_64, Nightly 49, 32bit, ID 20160526082509 STR_1: 0. Open page http://example.org/ 1. Open devtools -> options, enable "disable HTTP cache". Don't close devtools 2. Open http://i.imgur.com/rAX0Suq.gif in that tab 3. Watch until the gif starts looping AR: For the first time, the last part of the gif (~0.8s) is repeated twice. See "screencast 1" ER: Browser shouldn't randomly repeat any parts of gif. It should loop in a normal way Notes: 1) Reload the page to get the same effect again. Step 2 only required not to store gif in cache 2) I think the right component is image lib

Is that in a current nightly? I pretty sure I've specifically fixed a bug in the animated gif code that would cause exactly that effect.

I was not using 7 month old nightly at the moment I wrote this report (~2016-08-10). I won't update until I document all noticeable bugs on Nightly 2016-05-26 that are also present on latest versions. Yes, some of the bugs I reported today may already be fixed, but most of them aren't > Is that in a current nightly?

The video is recorded with reported version(!). Doing otherwise is just bad. I don't need to explain that your testing doesn't exclude false-positive results, but if you're so sure, mark this as "worksforme", but not "verified". (I'm pressed on time a bit, so I won't test it).

I tried the 2016-05-26 nightly and I was able to reproduce. Since the bug appears to be fixed for me I bisected to determine what fixed this and I got https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=2f8e2b313b7aee4466c2e71e034ac203807f330e&tochange=70369395b75433f29f313b7426681c2bd7ec4bc1 Which makes a lot of sense. If you get some more time I'd appreciate if you could re-test.
