About Browser Compatibility

jQuery actively supports these browsers:

• Firefox 3.6, 5.0.x, 6.0.x
• Internet Explorer 6+
• Safari 5.0.x
• Opera Current - 1 version
• Chrome Current - 1 version

Any problem with them should be considered and reported as a bug in jQuery.

There are known problems with:

• Mozilla Firefox 1.0.x
• Internet Explorer 1.0-5.x
• Safari 1.0-2.0.1
• Opera 1.0-9.x
• Konqueror

jQuery generally works with Konqueror and Firefox 1.0.x, but there may be some unexpected bugs since we do not test them as regularly.
