Suggestion: Autocomplete, don't save query parameters

Description

Started typing "paypal.com" into the address bar, was presented with numerous autocomplete suggestions that included query parameters. This could be viewed as a security risk.

Steps to Reproduce

Checkout with Paypal on a site. Then start typing paypal.com into the address bar, the site redirect URL and other information about the transaction is exposed because of the query parameters.

Actual result:

Expected result:

Autocomplete should only complete primary domain names and paths, but not include query parameters.

I'd also like to note that in addition to option to disable Autocomplete suggestions, it may also be worth including the option to disable all suggestions in the address bar. Even if you turn of URL and Search suggestions in Settings, you'll still be suggested sites based on history and Bookmarks. Users should be have an option to disable these as well.
