Firefox will no longer send search keywords to your ISP without your consent

Google Chrome and Mozilla Firefox are both widely used and together account for the vast majority of the browser market. Surprisingly, they all had a major privacy issue, where the user’s search term was sent to a DNS server in the ISP without the user’s consent. But now, Firefox seems to have solved the problem, and Mozilla gives users the option of banning search terms from sending to ISPs.

Firefox will no longer send search keywords to your ISP without your consent

As things stand, if you’re running any older browser than Firefox 79 or any version of Chrome, when you enter a search term in the address bar and select a search, the browser automatically sends the search term to one of your ISP’s (DNS) servers.

Interestingly, the browser sends your search term to your ISP only if the search term has only one word, and if you’re searching for a phrase, it won’t have this problem.

The good news is that if you’re using Firefox 79 (or Firefox 78 beta), there are a few simple steps to solve the problem:

Enter the out:config in the address bar

Enter “single” in the search box of the settings interface

Change the pref value of browser.urlbar.dnsResolveSingleWordsAfterSearch to 0.

Restart your browser

Just follow the steps above to prevent Firefox from sending search terms to your ISP.
