FF155 supports the dual-source blending feature in https://bugzilla.mozilla.org/show_bug.cgi?id=1924328
This adds the feature for Firefox desktop (FF android doesn't support the parent feature).
Note that I have explained what it allows you to specifically use, rather than what it allows you to do - because that's what the existing docs do, and because I don't know enough about Web GPU to be sure of what AIs tell me.
According to Gemini this allows you to blend two sources into a destination texture: your source and a per-channel mask. This allows control over the mixing of your source into particular colour channels rather than equally to all channels. Apprarently can be useful for some fonts etc.
Related docs work can be tracked in #45176
