That SharePoint team blog has posted an interesting article about which browser are supported in what level for WSS and the central administration web pages. In summary:
WSS3 knows two levels of browsers, Level 1 browsers and Level 2 browsers. Level 1 browsers can handle all functionality and experience options in WSS like ActiveX controls. basically the Level 1 browsers are IE6 and IE 7 for Windows.
Level 2 browsers are browsers that still work with WSS 3 but have limited user experience. The central administration pages can only be used with Level 1 browsers.
From the article:
“The good news here is that we have significantly improved SharePoint's cross-browser support in the new release compared to the current 2003 release. We've also been documenting where our features behave differently in Level 2 browsers, so customers can better understand what to expect when we release the new version. While subject to change before we ship, the current Level 2 web browsers are:
Windows
-
Firefox 1.5+
-
Netscape 8.1+
-
Mozilla 1.7+
Macintosh
Unix/Linux
-
Firefox 1.5+
-
Netscape 7.2+
Please note that the following web browsers, which were supported in previous versions of SharePoint Products and Technologies, will not be supported in the new version:
Here are some of the improvements that we have made in our Level 2 browser support compared to the previous version:
-
Most context menus are now supported in non-IE browsers. You'll notice that we've heavily integrated context menus into SharePoint with this version. These are the menus that appear when you hover over list items and click on the menu triangle, as well as list toolbars, view selectors, etc. By adding non-IE support to most of our context menus, not only will end users have a better experience interacting with SharePoint sites, but developers will benefit too. Now they can take advantage of the extensibility we offer in those menus and not have to worry about providing a separate code path for non-IE users.
-
Creating file attachments to list items is now supported in non-IE browsers. This was a popular request from previous versions, so we've extended that support beyond just Internet Explorer.”
