To disable search on url bar of Firefox, first re-enable the double search bar:
- Go to Settings
- Go to Search settings
- On Search Bar, select the 2 bar option
Now disable the search on the url bar:
- Visit on the main bar about:config
- Accept to continue
- Search “keyword”
- Change the status from true to false (double click on it)
Now if you try to type a keyword, you will be redirected to the keyword.com website, e.g. boh will redirect to boh.com.
Data aren’t sent anymore to other search engines except for autocompletes, but you can disable it following next steps.
Disable search autocomplete on urlbar
- Go to about:config
- Search browser.urlbar.suggest.searches
- Set value from true to false (double click on it)
Now if you type a search on the url bar, the search will be performed on the history alone, but if you use the search bar autocomplete will works normally.
The default configuration of Firefox can cause a search to be performed when an url is wrong using the main bar, or auto-suggestion to be performed silently.
At the end of this howto, Firefox will be back to a status where the user take back more control of searches, reducing disclosed data to external services.
