Internet Explorer 7 and Firefox 2.0 enhancements Both Internet Explorer 7 and Firefox 2.0 filter and analyze the Web address, the page content and the structure of a page. And, though both make use of blacklists, only Internet Explorer 7 offers this as a default setting. Firefox 2.0 makes up for this by offering the choice of two blacklists, one of which happens to be a live database maintained by Google. Also impressive is the speed...
with which all lists are updated.
Both browsers' development groups have upped the ante regarding user warnings, especially warnings applicable to providing personal information. Internet Explorer 7 now uses color-coded warnings in the URL bar based on whether a site is trusted and Firefox's dialog box to warn of cross-domain scripting. Internet Explorer 7 has also enhanced their default settings: the Medium setting has been raised to Medium-high, and the Low setting has been removed altogether. Unfortunately, the much-anticipated Internet Explorer 7 Protected Mode, which stops Web sites from changing a computer's critical files or settings, will work only in Windows Vista! Nonetheless, these improvements take steps to enhance the user experience as each browser now offers enough information to enable users to make intelligent decisions about the safety of a Web site.
Alternatively, Firefox allows Web pages to trigger a download dialog box that users must deal with. Firefox also has its own add-on model, and there are concerns about the ease with which they can be installed.
Firefox 2.0 vs. Internet Explorer 7: End-user appeal
However, Firefox 2.0 will likely appeal more to the technically knowledgeable user and its options and dialog boxes reflect that. It offers more customization, such as allowing users to choose which warning messages they receive, and which cookies they can view and remove. On the other hand, if Internet Explorer 7 considers its browser settings to be unsafe, the "Fix Settings for Me" option can help the less technically savvy surfer.
Presently, Firefox has a better reputation for security than Internet Explorer, but Internet Explorer 7 definitely reflects Microsoft's increased focus on security. Regardless, in order to consume Firefox's loyal user base, Microsoft has to show that it can match Firefox's fast response when new security issues arise.
