Description Grant Gayed CLA 2005-06-03 11:19:21 EDT 
Currently a page that has a javascript error (such as the page attached next) 
fails silently.  A callback for handling this should be added so that a Browser 
client can handle the error in a context-appropriate way.

Bug 77611 describes the spot where this can likely be hooked in IE.

I cannot find Gecko api for this.  I also notice that Mozilla and Firefox don't 
show errors in their status bars like IE does, so I suspect that this is not 
currently supported.

I have not investigated WebKit support.

Comment 0 lists only JavaScript errors, but there are additional sources of errors (and perhaps warnings) which a client of Browser might want to react to, for example:

- HTTP Protocol errors (for examples see bug 272680 and bug 286480)
- Security warnings or errors (invalid certificate, mixed https/http content)
- Other runtime error dialogs, I'll attach a screenshot of one.

Just for fun, I tried to find out how many recursive calls you can make back and forth between Java and JavaScript. Haven't tried it on the Mac or on Linux.
