Where do you see the exception?

What version of Firefox are you using?  Ideally you'd append "return false;"
inside the href= attribute.  In any case, javascript console shows nothing.

Perhaps it has something to do with the web developer toolbar?  That's the only 
extension I have installed.  I am even able to catch this exception with a try-
catch block.

Confirmed in FF1.0 on WinXP

Exception was:
Error: uncaught exception: [Exception... "Component returned failure code:
0x80004005 (NS_ERROR_FAILURE) [nsIDOMWindowInternal.focus]"  nsresult:
"0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: <unknown filename> ::
onmouseout :: line 0"  data: no]

This does not occur when you have disabled window.focus(), perhaps that is why
others are not seeing it (Tools > Options > Web Features > Javascript > Advanced
> Raise or Lower Windows)

This bug is part of a query for Firefox bugs that have Status set to NEW, but have version field set to 2.0 or older and have not changed in over 800 days.

If you still see this bug, or if it is still valid with Firefox 3.6.10 or a firefox 4 nightly build, please update the version field and steps to reproduce.
