Add Arguments to Google Searches de Theodric

You can heavily customize the results of a Google search by appending certain text to your query. This add-on allows you to add any such text/arguments automatically, and also to toggle these arguments on and off as you require.
For example, you could add:
1. -ai to remove all the Google AI suggestion nonsense (but leave knowledge boxes and highlights extracted from results)
2. -site:pinterest.* to remove all pinterest results
3. reddit to automatically favor Reddit hits
4. "potato" to only accept results which mention the humble potato

v1.2 adds a new toggle for the &udm=14 parameter, which eliminates all AI, knowledge boxes, highlights, and everything: just ten blue links, like it's 1999.
This add-on does not know who you are, does not care who you are, and does not collect any of your data.
