It really shouldn't the only reason it should crackle is if you turn the volume past 0db because some audio sources might peak.
Your issue of audio crackling is usually a non-grounded auxiliary or, a high memory latency / memory bug.
When I was on z97 and had my memory set to 2133mhz [a very high xmp value for ddr3] the audio constantly crackled when running certain applications. This can also be experienced when running with a lack of buffer while using an ASIO driver.
Completely unrelated to the plugin itself but maybe exacerbated by it.

If you open the popup to control the volume then on most sites that have html video it should be able to increase the volume unless the site employs a strict CSP.

The channels are not individually controlled so it shouldn't if you have issues with stereo you can employ mono.

Unless it's in the exclusion list, it shouldn't display this message. Please paste your log in the github issues..... you can also temporarily downgrade to an older edition from the github releases page or the versions page on mozilla https://addons.mozilla.org/en-US/firefox/addon/volume-control-boost-volume/versions/
Hope I can help you resolve your problem and you can revise your review to 5 stars. I jut do this as a hobby.

Its because steam blocks it in their CSP, sadly lots of CDNs do.
I could individually add each one to the FQDNS list, but like you said that's a lot of hassle and it has to be reaproved by mozzila everytime etc.
The way audio source is pulled is on page load. If it's doing it too late lots of sites won't interact with the plugin. Where as its an issue on sites with strict CSP as then it just blocks audio.
So sadly there's nothing I can do about it, without further reducing compatible sites.
Could maybe make a whitelist mode instead of a blacklist mode in the future.

I hope you revise your review as it "works good"

That shouldn't be possible its initialized per tab.

It works but some sites have CSP rules that block it from initializing/breaks audio. Add those sites to the blocklist in the settings.
