mynoise.net doesn't load fully

[Fenchelina]

The site mynosie.net offers several soundscapes. e.g. https://mynoise.net/NoiseMachines/water ... erator.php. It worked without any problems for a long time, but recently the integrated player no longer loads completely.: First, “Loading...” appears and runs through to 100%, then “Greasing sliders...” follows, but only gets to 95% and stops there.

Code: Select all

TypeError: Illegal constructor.

I don't know if this will help, but it seems the problem is in:

Code: Select all

cdnjs.cloudflare.com

With uBlock Origin active, I got these errors:

With uBo disabled, I got (basically) the same error as the OP:

Code: Select all

Error: TypeError: Illegal constructor.

If I'm understanding correctly, this is line 773 up to line 780:

Code: Select all

 dynCompressor=new DynamicsCompressorNode(context, {
    	  // working as a limiter
		  threshold: -12, 
		  knee: 6,          
		  ratio: 10,       
		  attack: 0.05,     
		  release: 2      
		});

It looks like it should work (at least, just with the context, not any options), but I don't see why it doesn't. Fortunately, there's an alternative function, so here's a Modify HTTP Response filter that seems to work (only tested this one, but it should work with others).

Code: Select all

[["mynoise.net",["/\\.php$/",["/new DynamicsCompressorNode\\(context, (\\{[\\s\\S]*?\\})\\)/","context.createDynamicsCompressor();Object.entries($1).forEach(e=>dynCompressor[e[0]].value=e[1])"]]]]

Thanks to Modify HTTP Response, the site is working again. A really helpful add-on!

Actually the “DynamicsCompressor” function recently was introduced as a new feature. There had been no problems before.
I doubt that uBlock has anything to do with it. When I encounter problems with a website, the first thing I do is disable the ad blocker and, if necessary, test it in a Palemoon without any add-ons. In this case, there was no difference.
Cloudflare and "Mousetrap"... this could be related to various measures taken by the site's publisher to ward off further hacker attacks. He mentioned something like this in his blog at https://mynoise.net/blog.php#pigeonthanks. It is possible that Palemoon stumbles across this and logs the corresponding errors.

Apparently the DynamicsCompressorNode (along with other AudioNodes) as constructor was implemented in Firefox 53, one version after our platform's fork point.
