Web browser compatibility

Most pages on this web site will work with any "version 4" or later browser. In practice, this means any browser released since 2000.

JavaScript is required by the search form and the result reports. Cookies are used for various purposes:

  • To save the contents of the User name and Email fields in the search form
  • To save search form defaults
  • If Mascot security is enabled, to save the session information

If saving cookies is not supported or disabled, it will be necessary to re-enter this information every time it is required.

The Protein Family Summary makes more demanding requirements on the browser than other forms and reports. The following table lists the minimum fully supported version of each supported browser. Older versions may work, but with fewer features or some layout problems.

We recommend upgrading your browser to the latest version or downloading a supported browser from the links in the first column.

Browser Minimum version Recommended version
Google Chrome 4.0 Any later stable version
Internet Explorer 6 8.0 or later
Konqueror 4.1 4.1 or later
Mozilla Firefox 2 3.6 or later
Netscape 9.0 9.0 or upgrade to another browser
Opera 10.50 11.00 or later
Safari 3.1 4.0 or later
SeaMonkey 1.1 2.0 or later


Internet Explorer 6, 7 and 8 do not support SVG graphics by default. We recommend installing Adobe SVG Viewer. Internet Explorer 9 and later have full SVG support.

Some Linux distributions ship with a rebranded version of Firefox or SeaMonkey; popular brand names include Iceweasel, Iceape and BurningDog. Recent versions of these browsers are fully compatible. Other browsers using the Gecko rendering engine (which is used by Firefox) are also fully compatible. This includes browsers such as Epiphany, Galeon and K-Meleon.

If you are using an alternative interface to Internet Explorer, such as Avant Browser, GreenBrowser, Maxthon or Sleipnir, note that the compatibility depends on which version of Internet Explorer is installed on your system.
