5 Security Features in Firefox

Security Features in Firefox

In some Linux versions of Firefox, Tools --> Options may be replaced by Edit --> Preferences

Never Remember Passwords

Tools --> Options --> Security --> Uncheck “Remember Password for sites”

Keeping this option enabled may have the risk of your online accounts being logged in without your permission since their passwords are saved. It is more catastrophic if the system you used is shared by others.

Block Pop-ups

Tools --> Options --> Content --> Check “Block pop-up windows”

As the name indicates, Pop-up windows are windows that pop-up when you are browsing through webpages. Many of the malware that come from internet spread into the system via the links/contents of the pop-up windows. One of the symptoms of a Malware attack is the appearance of pop-up windows unexpectedly and frequently.


Tools --> Options --> Privacy --> Check “Tell sites that I do not want to be tracked”

Some websites track your location and webpages you use to predict your interests.  These data are used to display specific ads based on your interest (known as behavioral ads) on the webpages you visit.

Private Browsing

Private Browsing generally saves you some disk place used for storing your internet history and offline cache, apart from saving your privacy. Keyboard shortcut for opening a new Private Browsing Window is Ctrl+Shift+P. It can also be accessed by clicking File --> New Private Window


Tools --> Options --> Security

--> Warn me when sites try to install add-ons

--> Block reported attack sites

--> Block reported web forgeries

These features offer additional browser security and help you from falling prey to phishing, malware etc. Firefox has a list of reported malware sites. Every time you visit a site, it compares the site with those in the list. If the comparison result is positive, Firefox blocks the site.

The first feature of Firefox, lets you know when any of the websites you visit try to install add-ons (with or without your conscience) on your browser.

Note: Add-ons are additional programs that complement your browser. A common example is Adobe Flash Player.
