The following review written by one of the Software Informer contributors applies to version 25.0
Firefox ranks among the most widely used web browsers. This preference is not casual if we take into consideration the multiple advantages this application has. Probably the most widely valued of its characteristics is speed, due to its highly efficient rendering engine.
However, this is not the only reason why so many users have chosen Firefox as their default browser. Other appreciated characteristics are its low usage of resources and its compatibility with various web standards.
Firefox has an easy-to-use, nicely designed interface. Moreover, if you do not like the default look, you will probably find another one you like, because there is an extensive set of skins available online. However, in my opinion, it does not look as streamlined as Google Chrome. As most modern browsers, it allows using tabs to browse various web pages at the same time. Some recent modifications to the way tabs are used include closing a group of tabs with a click, but it does not let re-open recently closed tabs right from the toolbar.
Although versions of this program are available for a long list of languages, it is a pity that you cannot readily switch between languages, something you can easily do in Chrome. Fortunately, it does allow spell checking in multiple languages.
In terms of security, Firefox is among the safest browsers. It uses strong encryption algorithms to protect your data when you are using the HTTPS protocol. Likewise, it uses smart cards for proper authentication and provides antiphishing protection. Unluckily, many users claim that the antiphising mechanism (consisting on sending data to online servers) opens a breach that lessens their privacy.
As said above, Firefox is compatible with various web standards. What is more, if you install an extension called IE Tab, this will allow you to use IE's rendering engine within a Firefox tab. This can solve the problems that appear when you try to open a web page using Microsoft web
- It is very easy to use.
- It allows browsing various web pages at the same time.
- It is fast and secure.
- It allows adding add-ons.
- It uses few resources.
- It is compatible with various web standards.
- It does not look as streamlined as Chrome.
- Once installed, you cannot switch the interface language.
