Browser Support

(Up to 'Technical Support')

We aim to provide basic compatibility with all common web browsers. Because we are using advanced XML technologies, however, not all browsers are able to take full advantage of the features of our content.

This page describes the current support for several popular browsers. Please click on the links below to read a full description of how each browser is supported as well as known issues. Please note that browser support may change in the future as new technologies are used and additional browser features are implemented. If you are using a browser not listed below, feel free to tell us about your experiences. While we cannot provide full support to all browsers, we do try to make sure that the site works for as many people as possible.

In order to properly view MathML content, including some of our most popular math and science material, you may need to install third-party fonts or plug-ins to work with your browser. See the full browser details below for additional information.

Fully Supported Browsers

Browsers with Limited Support

Unsupported Browsers


Fully Supported Browsers

These browsers are fully supported. New site features and bug reports are tested in these browsers to ensure compatibility. Any problems viewing content using these browsers should be reported to technical support. Please note that browser version numbers other than those listed here may not be fully supported.


Firefox 3

Firefox 3 is supported; however, we are currently investigating some of the changes to the way MathML have affected the display of some content. While we are committed to resolving these issues and moving towards full support, please note that we are not able to guarantee that all MathML content will be accurately displayed at this time.

Firefox 3 users should download the STIX Beta fonts and install them according the instructions provided. Important! These fonts are required in order to properly display MathML content; while content may appear to display correctly without these fonts, failure to install them could result in subtle but important changes to some expressions.

Note: If you are upgrading from Firefox 2 to Firefox 3 and had previously installed the fonts for Firefox 2, you will need to uninstall those fonts before attempting to use the Edit-in-Place authoring interface. One of the fonts (cmsy10.ttf) is not compatible with Firefox 3 and causes strange characters to be displayed when using Edit-in-Place wherever MathML is used. These characters only appear in the authoring interface and do not get displayed when the module is viewed online or in print. To resolve this issue, simply remove cmsy10.ttf from your system fonts. If you used our installation program to install these fonts on a Windows-based computer, you can remove them using the uninstaller program through the Add/Remove Programs control panel.

You can download a free copy of Firefox 3 at http://www.mozilla.com/en-US/firefox/.

Browsers with Limited Support

These browsers are known to work with the website, but are not necessarily tested during the development of new features. Though we do not anticipate any problems, please note that you may encounter unexpected results when using the browsers listed below. This section also includes browsers that have previously been supported, but are now considered outdated.


Opera 10

Opera 10 introduces native support for MathML, an exciting new development that propels this browser into the ranks of partially supported browsers. Our testing so far has shown success not only with displaying MathML content accurately, but also working in the Edit-in-Place authoring environment, making it a viable candidate for authors and end-users alike.

Please note that we do not currently test new features and site updates using this browser, and are not prepared to offer full support at this time. You may receive a warning about MathML being displayed incorrectly when viewing a MathML-enabled module; while our tests have shown success with rendering MathML in the Opera browser so far, we require additional testing before we can assume that the math output is accurate in all cases.

If you experience any problems using Opera to either view or create content, please let us know.

You can download a free copy of Opera 10 from the Opera website.

Firefox 2

Firefox 2 is fully supported. In order to properly display MathML content, however, you will need to download a set of fonts that will allow your browser to properly display MathML content. Windows users can use our MathML font installer for Firefox 2.

You can download a free copy of Firefox 2 from the Mozilla Foundation website. Please be aware that installing older versions of the Firefox browser may expose you and your computer to known security risks as described in the link provided above.

Mozilla 1.8

See description for Firefox 2 above.


Netscape 7

See description for Firefox 2 above.


Internet Explorer 6

We have included Internet Explorer 6 for several years as a fully supported browser; however, this version of the software is now out of date. Future development will focus on compatibility with Internet Explorer 7 and later, and while we do not anticipate any specific problems with using IE6 in the future, we are no longer able to guarantee that all of the site's features will continue to function in this browser. We strongly encourage users interested in using Internet Explorer to update their browser software to the latest version before using our website.

In order to properly display MathML content, however, you will need to install the MathPlayer plugin by Design Science.

Unsupported Browsers

These browsers are not compatible and are not supported. If you currently use one of these browsers, please consider switching to one of the supported browsers listed above.


Chrome

Google's Chrome browser has not yet been evaluated. At this time it appears that Chrome does not support MathML. There are currently no plans to provide support for this browser, though we will continue to monitor developments and may consider support in the future if our evaluation yields positive results.

If you have experienced any problems or success using Chrome to either view or create content, please let us know.


Safari

Safari currently does not support MathML content, and does not work with the Edit-in-Place authoring interface. Due to these limitations we are unable to provide support for Safari at this time; however, there are no reports of problems using Safari to view non-MathML content or edit modules using the full source editing mode. We will continue to monitor future Safari developments, particularly with regards to MathML support, and may consider support in the future.

If you have experienced any problems or success using Safari to either view or create content, please let us know.
