Finally figured it out. Add "-noai" to any google search to remove the AI sprinkles from your search results
Even better, add `&udm=14` to a google search URL to just show links. No summary boxes, no AI sprinkles.
To add this to your Firefox:
* Go to about:preferences > search
* Go down to the list of search engines and hit the Add button
* Set the URL to be: https://www.google.com/search?q=%s&udm=14
* Give it a one-letter shortcut, like @g, so it's easy to toggle it (or you can just make it the default)
* Search the web like it's 2005!
