    <thetext>https://dvcs.w3.org/hg/FXTF/raw-file/default/filters/index.html#feTurbulenceNumOctavesAttribute

Should read:
[[
    The numOctaves parameter for the noise function.

    The lacuna value for ‘numOctaves’ is 1.

    Negative values are unsupported.  This value should not be greater than 10, as higher values are not likely to have a noticeable effect.

    Animatable: yes. 
]]

This is because the Firefox team recently implemented a limit to this value in order to prevent Firefox from hanging if numOctaves is much too big. As noted in the issue [1], &quot;octaves changes have a smaller and smaller effect as they grow larger&quot;.
