Current desktop machines are equipped with multi-core processors, gigabytes of system RAM and the ability to run many programs simultaneously. With the huge range of system resources available it is not surprising the software bloat phenomenon is witnessed. This is a process where successive versions of an application consume more system resources than necessary, or offer an ever-increasing number of features that the majority of users do not use or need.
The field of web browsers is dominated by Mozilla Firefox, Google Chrome, Internet Explorer, Safari, and Opera. To try to counter software bloat, the developers of these browsers make use of plug-ins, extensions or add-ons. This means that the extra functionality offered by these tools are made available to only those who actually need them. Nevertheless, these web browsers still have one thing in common; they do not have a particularly small footprint. Whilst they run fast on a well specified modern PC, there are many users that are using much more limited hardware. These low spec machines can be extremely popular.
