The crash doesn't happen in 2.0. Reproducible: Always Steps to Reproduce: 1.Go to the specified URL. Actual Results: Firefox crashes. Expected Results: It should either throw a JS exception (like 2.0 does) or not treat onload() as a special function (like other browsers).

I just inadvertantly hit this myself, an "onload" handler named "onload" causes an immediate crash in 1.5.0.9 <html> <head> <title>OnLoad Test</title> <script> function onload() { alert("onload()"); } </script> </head> <body onload="onload()"> This is the body </body> </html>

WFM Ubuntu Edgy FF2.0.0.1. Firefox doesn't crash, but firebug alerts me "too much recursion". Robin
3.5 still has the infinite recursion issue (no crash though). Firebug shows the code from the "onload" attribute is actually being put into a function named "onload". Not a huge problem, but seems like something that ought to be fixed. In my case I had my PHP backend automatically adding the onload attribute if it found a script for the current page with a function by that name, and scratched my head a little while wondering why it didn't fire.

Same for me on Vista with Firefox trunk; "infinite recursion" error message but no crash.
