Choosing Browsers to Test Against
We strongly recommend that you test your websites with at least Internet Explorer 6 and 7 and Firefox 2. At the time of writing, these three browsers account for over 90% of the market.
Firefox is stricter in its support of web standards than Explorer, and some code that is not standards-compliant will work in Internet Explorer but not in Firefox. Identifying and fixing such code will help to ensure that your site conforms to standards, making it more likely to be compatible with any given browser.
If possible, we recommend that you test your site against other browsers: Opera, Safari, Internet Explorer 5, Firefox 1.5 and Konqueror which all have a small share of the browser usage market, and additionally older browsers such as Netscape 4 and Lynx. Testing with Netscape 4 and Lynx ensures that your site is accessible to browsers with very basic functionality, which increases the likelihood that it will work with any given browser, for example proprietary browsers used by mobile devices.
You can download all of these browsers free for Windows, Unix and MacOS X:
|Browser||Windows||Unix-like (e.g. Ubuntu Linux)||MacOS X|
|Safari/Konqueror||Safari 3 Beta||konqueror.org||Safari 3 Beta|
|Netscape||Navigator 4.08||Communicator 4.8||Navigator 4.08|
|Lynx||Lynx on Windows||lynx.browser.org||Apple.com|
|Internet Explorer||Multiple versions of IE (3,
4.01, 5, 5.5 and 6) on one machine
