are you sure you are writing about our extension? Nothing you describe makes sense. Perplexity isn't even a default search-item at all. So either you have created and added it yourself and can remove it the same way or you are talking about the search-engines showing in your address bar which are added by Firefox and not our addon.
Trufflepiggy - Context Search appears only in your context menu when you right click on some text or images. It doesn't overwrite your URLbar search engines. So please rereview your review and feel free to contact me via our support page.
