It was not always correct, as the size can't be always determined, but it showed some minimum value. There is nothing similar in Mozilla AFAIK. Even the render time of a page is gone. This was probably of no value because it was usually nonsense. And mozilla is so slow (on Linux), that it takes the same time to download and render a 1K page and a 50K one - about 2secs on my machine. Therefore currently only one usefull figure came to my mind - total size of all files used to render the current page and show this in the status bar. This even doesn't need tu be realtime or while downloading. It is sufficient to show it after everything is done. This would require to iterate over all links going from the current page and counting the sizes of the referenced files (maybe recursively for frames and such). Why is this useful? As I said in the 1st paragraph, a page rendered in 2seconds says nothing about its size. If this counted value would be available, every user (from web designers to novice users) would see which sites are bloated and which are not. I think this is easy to implement and it could be done incrementally. For start, count all images, next time, add style sheets, etc. Of course it can also be done on the network layer or cache. That's why I put it here, but never mind to change the category as I didn't find a good one. Reproducible: Always Steps to Reproduce:

Networking. Doesn't sound like cache to me... The duped bug is in File Handling, don't understand that either...

That's questionable. If you are offline, the page is fetched from the cache. And the byte count is known. There may be no networking - of course, if it isn't in the middle: load -> networking (just forwarding if offline) -> cache.
