Hello, is it possible the context menu can be simply clicked and use the last used search engine and then please allow us to remove the original Firefox context menu item 'Search for'
Unfortunately those are both things that Firefox does not allow. In the current way Firefox add-ons are made (WebExtensions), they cannot remove from the context entries that do not belong to themselves.
Clicking the SSS context menu parent "Search for" also seems to always do the default behaviour, which is to simply open the sub options, so SSS isn't even notified of a click there. Sorry I can't be of more help!
