No. Nothing after enabling the video. And it's not the default security
level, because it's what you should change first to test NoScript.

installed a different NoScript version (not the one shipping with the
browser). But you're standard, it seems.
Those options are incompatible with anonymity, so they should be
explicitly specified.

> My answer is irrelevant, because even if I develop NoScript, I do not
ship in the Tor Browser neither decide its configuration presets. On the
other hand, you actually answering my question would have been helpful, as
the security level determines what you can expect to be the "normal"
behavior.
Updates land automatically on the stable TBB, bringing a lot of pain
sometimes...
> However I've just tried to reproduce any anomaly on a fresh Tor Browser
8.5.4 installation w/ default NoScript 11.0.2, both on Linux (Ubuntu
18.0.4.3 LTS), macOS Mojave **and Windows 10**. I obtained the following
expected behaviors for each of the three security levels, upon opening
https://www.sample-
videos.com/video123/mp4/720/big_buck_bunny_720p_10mb.mp4:
>
> 1. STANDARD: the video plays as soon as the page loads
> 2. SAFER: I get a window-sized placeholder, which if clicked opens a
prompt to let me decide whether letting the video play. If I authorize it,
the video plays as expected
> 3. SAFEST: like n.2 (SAFER)
>
> I cannot test on other platforms, but a Windows 7-specific bug of this
kind would be extremely weird.
Yes, Windows 7 is specified in the summary of this ticket.
> Can you actually observe anything different?
> If you can, what is that?
