1. Text box inside DIV
For some weird reason in Firefox 2, the cursor caret in the text box disappears when the text box is inside a DIV. Web developer has to work with the CSS hack to get the caret back
overflow: hidden; position:fixed;It is OK if web developer have the total control of the HTML. However, we have web components in .Net and Java Server Face. If such components do not aware of this, user may had a bad experience.
2. Length Required with POST
Content-length is an HTTP header letting the server know how much data it should be expecting in the request. However, Firefox does not send such header to the server with posting with XMLHTTPRequest. Developer need to write it out explicitly
xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded')XMLHTTPRequest is the key doing AJAX! The HTTP request is usually uncachable when using POST. Why on earth developers need to code it themselves?
I think implementing the standard is important. It relieves the web developers headache. On the other hand, please do not introduce new problem to the developers.
