Your English is just fine. Ignore the losers who harp on typos and misphrasings -- EVERYONE does that.
I don't know the answer to your question, but (What on Earth are you downloading? :-) ) may I suggest that you save the HTML page and chop it up into 9,000 chunk items in your favorite HTML editor, then load each page seperately and specify things that-a-way.
Conversely you might try sorting, selecting chunks with SHIFT, and/or using the Regular Expression filters.
NOT the answer that you wanted, but that might get you limping along. Alternatively, look at FireFox 56 (and below) and Down-Them-All for this. Or look at WGET and feed it a list of URLs. It'll eat ANYthing at all.
