Firefox browser to support the standard MAX_FILE_SIZE

Do you want the MAX_FILE_SIZE upload feature to work.
It's even in the standard, every browser I've tried it on doesn't react, not even Firefox which is said to _fully_ support HTML and all it's flavours.
It saves you and everyone who uses your homepage a great deal of trouble if the browser would report if the file is too large and don't upload it!
I quote from the PHP Manual: (php.net/manual/en/features.file-upload.php)
"The MAX_FILE_SIZE hidden field (measured in bytes) must precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. Fooling this setting on the browser side is quite easy, so never rely on files with a greater size being blocked by this feature. The PHP settings for maximum-size, however, cannot be fooled. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed."
It says it all, go ahead and sign :)
