Introduction to How Firefox Works



A Web browser is sort of like the tires on your car.
You don't really give them much daily thought, but
without them, you're not going anywhere. The
second something goes wrong, you definitely
notice.
Firefox History
The origins of Firefox can be traced directly to
Netscape, a compan?y whose Web browser,
Netscape Navigator, was the dominant browser
before Microsoft developed Internet Explorer. The
internal company name for the browser was
Mozilla. Eventually, Netscape released the source
code for Navigator under an open source license,
meaning anyone could see and use the code. A
non-profit group was set up to direct the
development of browsers using this code. This
group became the Mozilla Foundation in 2003.
Firefox Basics
The easiest way to learn about Firefox is to go
ahead and download it (it's free). You can find it at
the official site: http://www.getfirefox.com. There
you'll find the latest version of Firefox: Firefox 3.5.
If you're hesitant to install and learn to use a new
program, rest assured that Firefox looks and acts
very similar to Internet Explorer and most other
Web browsers. There's even a feature for IE
users that lists the expressions with which you're
familiar and tells you the corresponding Firefox
names for those functions.
Firefox Features
Firefox comes with a few useful features that set it
apart from earlier versions of Internet Explorer --
so useful, in fact, that virtually every other
browser, including Internet Explorer, Opera, Safari
and Google Chrome, has also adopted them. One
of the most noticeable is tabbed browsing. If
you're browsing in Internet Explorer 6, and you
want to visit a new Web site while keeping your
current one open, you have to open a completely
new browser window. Intensive Web surfing can
result in browser windows cluttering up your
taskbar and dragging on system resources.
Firefox solves that by allowing sites to open in
separate tabs within the same browser window.
Firefox Security
Firefox simply handles security differently from
Internet Explorer. Where Internet Explorer uses
security zones, which can sometimes be confused
by malicious software, Firefox does not rely on
zones. Also, Firefox doesn't use digital signatures,
which are verifications programmers can
purchase. If you try to install software on your
computer, Internet Explorer checks to see if the
digital signature matches the actual vendor of the
program. Peter Torr, a program manager at
Microsoft, pointed this out as a serious flaw in
Firefox's security.
