When I'm developing I like to have the Web Developer's extension check for Javascript errors & warnings. http://chrispederick.com/work/webdeveloper/ (works with FF, Mozilla, Seamonkey & Flock).
In FF these JS options are in Tools / Web Developer / Options / Options / Miscellaneous. If I have them switched on the Xinha throws up quite a few errors. I don't think most of them are anything to do with my site though.
Have submitted this as a new ticket (Ticket #846) but I was hoping someone else might have come across this too and have a solution - could it be something to do with the way I'm using Xinha rather than a real code problem? Here's a sample
Warning: anonymous function does not always return a value
Source File: http://localhost/XINHA/htmlarea.js
Line: 532 Source Code: };

...
Warning: redeclaration of function stripTag

Thanks.

Hmm. Seems I didn't have a very recent version installed after all. I do now though - just down-loaded a couple of minutes ago - and similar problems (lots of Javascript warnings) are still there. Part of the problem is that Firefox is complaining about a css property and throwing an error - not a Xinha problem of course - Mozilla & IE don't complain.
Error: Unknown property 'filter'. Declaration dropped.
Source File: http://localhost/XINHA/htmlarea.css
Line: 50
.htmlarea .toolbar .buttonDisabled img {
filter: gray() alpha(opacity = 25);
-moz-opacity: 0.25;
}

The filter property warning you mentioned is the result of using IE 5.x / 6.x specific way of setting opacity for disabled buttons. As rendering engine simply skips unknown propertfies in CSS files, it does not case any trouble in UI. I personally would not be concerned about errors showing up while strict warnings are shown up by Webdeveloper extension. But - still - this is just my personal opinion.
