We have shown in past articles like Gmail login or Facebook login how to handle security and login problems on those sites.
This article takes a closer look at some general options that Firefox users have to increase their online security. We have already reviewed two Firefox add-ons in the past, the Last Pass password manager that can generate and remember secure passwords, and the Web of Trust extension that scans links and warns the user if websites are not to be trusted or outright malicious.

I tend to get many requests from people all over the world who like to know if there is a way to find out if a website on the Internet is malicious in nature or dangerous in other ways before accessing it.
There are actually a few possibilities to handle that. Most of these require specific IT knowledge however to look up server and domain information at the domain registrar and query databases that contain relevant information.
A better option for most users is to install a web browser extension that handles all of that for them. And one of those extensions is the Web of Trust extension which is available for Mozilla Firefox, Microsoft Internet Explorer and Google Chrome.

Whenever you want to signup for a new service on the Internet you need to fill out at least a handful information on the signup page. This usually includes at least an email address, username and password for the service but often additional personal information such as your name, birthday or address. All of those information can be filled out manually which quickly becomes a nuisance if it is done on a regular basis or by using a web browser add-on that can fill out forms automatically.
The excellent password manager Last Pass, which we have reviewed in the past, can be used to fill out forms automatically as well. It supports multiple profiles that need to be created once by the user so that they can be used to fill out forms whenever it is needed. This simplifies and automates the process.
Here is how it is done:
You do need the Last Pass add-on which is available for the web browsers Firefox, Google Chrome and Microsoft Internet Explorer. The form filler is automatically included in the add-on. A new profile can be created by right-clicking on a blank spot on a website in the web browser and selecting the Last Pass Fill Forms options which opens a submenu with options to add or edit a profile.

You probably have come upon password security questions before. They are often used when a user forgets the password to an account to identify the user. The major problem with those security questions is the fact that they often only display general questions that the user can chose from during configuration. This includes the mother’s maiden name, the first school, the favorite sports team or the birthplace.
Asking those questions is problematic because of two things. First, they are not that secure if the attacker has access to information about you. Your mother for instance would surely know most of the answers to those questions, as would a close friend and even most work colleagues or class mates might. The second problem with these type of questions is that they can also be easily guessed. The number of possibilities is a lot smaller than the number of possible passwords for an account meaning an attacker could simply try the most popular answers to see if they would be a hit.

Security is important. Computer security basically consists of protecting data from unauthorized access. Data can be anything from files on the computer system over personal information of the user to tax documents, photos or credit card transactions. Many Internet users do not see it that way and reduce it to protecting the computer against computer virus attacks.

If you ever worked in tech support you know that there are users who have to use computers without having a clue what is going on. Those users open a website by entering its url in the search form, click on links in emails, open attachments and do many other things that experienced computer users call foolish or at least a security risk.
I have met many PC users who could not tell me on which website they were currently on and it took a lot of navigating around before they could tell me.
This guide is for those users. It will explain how to find out on which website you are and if it is the right website. This may sound trivial to experienced users but believe me when I say that it can benefit inexperienced users.
This guide will use Microsoft’s Internet Explorer 8 web browser. Other web browsers, like Firefox, usually have a similar layout.
