I don't like the new feature that was introduced in [https://www.mozilla.org/en-US/firefox/83.0/releasenotes/](firefox 83). >Selecting a search engine at the bottom of the search panel now enters search mode for that engine, allowing you to see suggestions (if available) for your search terms. The old behavior (immediately performing a search) is available with a shift-click. I would like to revert the old search selection behavior. What spell do I need to add to about: config to revert the old default behavior?
