பயர்பாக்ஸ் ஆதரவு மன்றம்

I want to permanently and repeatedly disable part of a website that messes up the layout. I get a VEEERY long slider at the bottom when the element is present with a never ending page.

I found out using the inspector which element of the page was doing it and if I "delete the node" the website appears completely normal.

The line in blue is what I want to delete permanently. And it is gone on the second upload.
