Today I tried to use profiler.firefox.com which is some webapp that Mozilla makes to help you profile webpages in Firefox.
I have a simple webpage I wanted to profile which just has a small script and almost no html. I captured a profile and then in the profiler UI if I click the Firefox 78 tab a the top it shows I have a bunch of extensions installed.
I never installed most of these extensions. I never installed a Wikipedia extension, nor Bing, nor Amazon, nor eBay, nor DuckDuckGo.
Checking the adds-on UI they don't show up there
How do I get rid of these extensions?

They are not extensions they are Search Engines. They are not being classified correctly by the profiler.
To remove them:
Open the Search panel in Firefox Options using one of these methods:
Click the menu button and select Options. In the Options tab that opens, click on Search in the left pane.
If you added the optional Search bar, click the magnifying glass on the Search bar and then click Change Search Settings.
Under One-click search engines, click on the search engine you want to remove.
Click the Remove button to take it off your list.
