Referring to this question , how can i get the current page size in kb, this size i will use to know the connection speed for this page.

Answer 1

To get the file size of pages on the web I built a javascript bookmarklet to do the trick. It alerts the size of the page you're on in kb's. Not sure if it can help with connection speed though.

Change the alert to a prompt if you want to copy the filesize.

Here's the bookmarklet code for the alert.
