Description

[Daniel Holbert [:dholbert]]

STR:
 1. Visit this URL, in Firefox for Android:
https://video.xx.fbcdn.net/v/t42.9040-2/10000000_1267944863348813_4247598226246467584_n.mp4?_nc_cat=105&efg=eyJybHIiOjgxMCwicmxhIjoxNDcxLCJ2ZW5jb2RlX3RhZyI6InN2ZV9zZCJ9&_nc_ht=video-atl3-1.xx&oh=c34cb80d9a42925321e0a6bc6d89a96a&oe=5C14F818

 2. Try to seek forward in the video by tapping somewhere on the time scrubber bar.

ACTUAL RESULTS:
The video gets a gray sadface overlay saying "Video playback aborted due to a network error".

EXPECTED RESULTS:
No such issue.

I don't get this issue in Chrome on Android, nor do I get it in Firefox/Chrome on my laptop.

Tested & confirmed affected:
 - Firefox 63.0.2 for Android (the release version I've currently got, haven't received a 64 update yet)
 - Firefox 66.0a1 Nightly for Android

Hardware: Pixel 3 phone, running Android 9 (P)

Yeah, I can't reproduce anymore. I don't recall where I found the original video, but today I tried a few videos (each one more than a few minutes long so that they'd be usefully seekable) from https://m.facebook.com/caltrain/video_grid/ and didn't have any issues.
