Is there any way to make the search bar become cleared again whenever you search for something?
(Note: This is about the search bar -- I do NOT want to clear my entire history just to get rid of this!)
Try clearing your saved form data. Most browsers have an option for this when clearing browser history and will let you choose what you want to clear (i.e form history) while still preserving other things (i.e browsing history, cookies, etc)
If it's something that you deal with often, try using another browser profile where you can set the preferences to delete your history when you close the browser.
Or in Firefox, try using private browsing for activities that necessitate eliminating the search history :)
IF you want to go the addon way, try this addon
Is already answered, but try this (Looks like more easier to me):
