@sgunhouse Thanks for the help, everything works like clockwork. You can add, delete, swap "search engines" in "settings" - "basic" - "search service" - "search engine management."

Thank you, as I did not look, I could not find how it is properly called. Due to the incorrect wording of the request, it is simply not realistic to find a result in the RU zone.

How to add or remove "search engines?"
For example, the copied "text" or "product name" through the context menu "search in" search on YouTube.
How to add to the context menu "search wiki", "search in YouTube", "search in - with a link to the search site where to search."
TY!
