K-Meleon does have progress loading bar (bottom right corner), but it tells you
almost nothing about how your web pages are loading. A "real" progress bar
let's you know that each page successfully loaded or failed.
There are extensions for Firefox and other browsers that display a progress
loading bar inside the location or address bar.
Here is an example:

Is there a progress loading bar extension for K-Meleon?
