Browser.urlbar.filter.javascript

Bookmarklets create history entries which can then appear in the Location Bar’s autocomplete dropdown. To prevent this, the Location Bar will filter out any URL starting with “javascript:”. This option is toggleable via this preference.

Possible values and their effects

True

Filter out “javascript:” URLs from appearing in the Location Bar autocomplete dropdown. (Default)

False

Allow “javascript:” URLs to appear in the dropdown.
