[RESOLVED] Gecko 42 - mediasource: not listed in NS menu

Post by barbaz »

SeaMonkey 2.39, Linux x86_64

Is this due to a change in Gecko, or is it a NoScript bug?
Also can someone please check if it's the same in Firefox 42.0?

STR:
1) make sure MSE is eabled and check that with https://www.youtube.com/html5. In my case all listed features are shown as supported
2) go to some youtube video, say https://www.youtube.com/watch?v=CbEpfji2P18
3) after getting the video to play, open the NoScript menu

I see no 'mediasource:' listed there, even though the youtube's own "Stats for nerds" says DASH is enabled, resolutions only available via MSE are listed as available, and ABP blockable items shows the video fetched in chunks by XHR (consistent with youtube using MSE).

Code: Select all

No "mediasource:" and no DASH.

Exact the same with SeaMonkey 2.39

Guess I wasn't clear with my STR #1.
I do not use default settings for mediasource related stuff.

I'm sorry, the "default settings" was more likely a misunderstanding of mine... :oops:

Me neither.

In FF 42.0, with all the features listed in https://www.youtube.com/html5 supported, there's no "mediasource:" entry in NoScript's menu.

Thanks for checking that.
Any idea why this changed with Gecko 42?

Investigating.
However that's definitely not a NoScript bug, since Gecko appears not to call nsIContentPolicy.shouldLoad() anymore for mediasource: URIs: either they're not invoked at all in Firefox, or some new code is working around content policies on purpose (unlikely) or because of a Firefox bug.

Fixed in 2.9.5 in a different way (the codec mediatype actually in use are detected).

Reason: fix script-caused error :)
