In fact, "about:memory" does show separate memory allocations per tab. Look under "explicit", "window", and you'll find a thing named "tiny", this contains most of the windows (it's a tree, click to expand). There are also a number of tabs not in the tiny branch, which are considered a little too big.
- annnnd 12y agoThanks, but if I understand correctly, not all tabs are there and this is not their total memory usage. If this is so, then this is not what I meant. I meant a single indicator of tab memory usage in a similar way PSS is calculated [1]. That is: all the memory resources this tab uses (including JS) plus appropriate share of the shared resources. From user's point of view I don't care HOW the page/tab uses my memory - I just want to know how much of it it used. [1] http://lwn.net/Articles/230975/ http://lwn.net/Articles/230975/
- nnethercote 12y agoAll the tabs are there. Look at the "top(...)" entries just below "window-objects". Most of the per-tab memory is correctly reported there. Images are the main thing that isn't reported on a per-tab basis.
