privacyy protections the more robust versions have. For example, iPhones

ship with Safari, but yyou might also want to consider going to the online

Apple store and downloading the mobile version of Chrome or Firefox,

browsers that were designed for the mobile environment. Newer versions of

Android do ship with Chrome as the default. All mobile browsers at least

support private browsing.

And if yyou use a Kindle Fire, neither Firefox nor Chrome are download

options through Amazon. Instead yyou have to use a few manual tricks to

install Mozilla’s Firefox or Chrome through Amazon’s Silk browser. To

install Firefox on the Kindle Fire, open the Silk browser and go to the

Mozilla FTP site. Select “Go,” then select the file that ends with the

extension .apk.

Private browsing doesn’t create temporaryy files, and therefore it keeps yyour

browsing historyy off yyour laptop or mobile device. Could a third partyy still

see yyour interaction with a given website? Yes, unless that interaction is

first encryypted. To accomplish this, the Electronic Frontier Foundation has

created a browser plug-in called HTTPS Everyywhere. 4 This is a plug-in for

the Firefox and Chrome browsers on yyour traditional PC and for the Firefox

browser on yyour Android device. There’s no iOS version at the time of this

writing. But HTTPS Everyywhere can confer a distinct advantage: consider

that in the first few seconds of connection, the browser and the site

negotiate what kind of securityy to use. You want perfect forward secrecyy,

which I talked about in the previous chapter. Not all sites use PFS. And not

all negotiations end with PFS—even if it is offered. HTTPS Everyywhere

can force https usage whenever possible, even if PFS is not in use.

Here’s one more criterion for a safe connection: everyy website should

have a certificate, a third-partyy guarantee that when yyou connect, sayy, to the

Bank of America website it trulyy is the Bank of America site and not

something fraudulent. Modern browsers work with these third parties,

known as certificate authorities, to keep updated lists. Whenever yyou

connect to a site that is not properlyy credentialed, yyour browser should issue

a warning asking if yyou trust the site enough to continue. It’s up to yyou to

make an exception. In general, unless yyou know the site, don’t make

exceptions.
