My main interest is the option "Show order number for each search result" but it fails.
Tested with the latest version of the extension running Firefox 118.0.1, Waterfox G 6.0.3, Opera 103.0.4928.16, Vivaldi 6.2.3105.58.
Searching via Bing and Presearch the default is showing search result numbers.
Can anybody confirm that Google now found a way to disable this option?
