When I visit Amazon, the search bar is always auto-filled with a particular phrase (“Applied Network Security Monitoring”), a search I requested 10 years ago. It is specific to Firefox, and specific to my preferred account.
Recent changes at Amazon now cause the whole screen to gray when that term is added to the search bar.
I have searched through the prefs files, and any other files that looked likely, for that phrase; no success.
Where would I look for the rule that adds the search phrase to Amazon’s site? And expunge it?
