User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:49.0) Gecko/20100101 Firefox/49.0
Build ID: 20160511030221

Steps to reproduce:

Play a video on YouTube, switch to a different tab, switch back to YouTube video after a short time on other tabs.


Actual results:

After a couple seconds the audio restarts from the beginning while the video continues playing normally (sometimes with the proper audio still playing as well). Skipping forward/back in the video fixes this temporarily until the next time switching away from then back to the video's tab. (Worth noting, this issue first appeared in the nightly build from May 12th, and is not present in the build from May 11th.)


Expected results:

Audio should remain synced to the video when switching back to the video's tab, it should not restart from the beginning while the video continues playing as normal.
I can reproduce this issue too.

Can confirm that I have the same issue!
