window.status
Web developers:
If you are fond of setting the window.status of your pages (that text that appears in the lower left-hand corner of your browser window), take heed. It now appears that Mozilla is suppressing this by default. Therefore your target users would have to check “change status bar text” in the advanced Javascript settings in order to see any of your manipulations. This makes window.status seem on the road to deprecation. Safari still seems to support window.status by default, and I guess I’ll check it out in IE 7 when they finally release it.
