Actual results:

memory usage increases from 200 MB to > 1GB

even after a restart of firefox the problem persists
if have test this with firefox 7 beta where are all addons disabled
I can confirm on FF6 (will test 7-8 later). The page is quite short, there must be some problem with it why it takes so much memory (according to windows task manager).

Even about:memory shows broken values (see the ~400% and ~-400% entries) and a lot of memory in gfx-surface-win32:

For me FF has virtual memory size of 900MB, working set also 900MB.
IE8 allocates virtual memory size of 600MB, but working set is only 140MB. And Firefox has really allocated the memory and it is used (committed), my 2GB computer swaps heavily.
On Linux FF7 it gets interesting. about:memory also shows wild numbers. However the system (top program) does not. top shows the same number as vsize.

aceman, on Linux we store images in the X server's memory.  Were you looking at that in top, or just at the Firefox numbers?
So what this page does is load 240 images into the slideshow.

Each image is 838x559 pixels.

We decode the images into RGBA surfaces.  So each image takes 838*559*4 = 1,873,768 bytes.

The total memory used by all the images should then be 449,704,320 bytes.

I'm not sure why the actual memory increase is about 1.5x that.

I'm pretty sure that IE does some sort of lazy image decode thing...

Also, why is this marked "mlk"?  Do we not release the memory once the image cache is emptied?
Sorry about that. Yes, fortunately, the memory is nicely released after closing the tab.
I looked on the X process but can't draw any conclusions. It changes memory size frequently but I can't see any big increase (or decrease after tab close). The difference is about 100MB. But it surely doesn't have those ~800MB allocated.

The page loads lots of non-thumbnail images hidden behind CSS.
Yes, there are many images, but they are initially hidden. May be a candidate for decoding the images only when needed, even if it is the active tab.

The bogus about:memory numbers may be fixed by bug 664659, which was fixed in Firefox 8.

It'd be nice to have numbers from other browsers.  In general "webpage uses 1GB of memory" is not clearly a problem;  that amount of memory usage may be entirely reasonable, depending on what the page is doing.  "Webpage uses 1GB of memory in Firefox, but only 100MB of memory in all other browsers" is clearly a problem.
Summary: memory usage increases to> 1GB on single page → memory usage increases to > 1GB on www.welt.de slideshow

It seems FF decodes all images beforehand into gfx-surface-xlib, it roughly matches the calculation in comment 6.
Switching away from the tab in FF and switching back to the tab after a while takes a bit, maybe it is redecoding all the images (discard period in FF9 is 10s).

This does not happen in e.g. chrome. It seems to decode images only when they are exposed (there are button for the slideshow on the page) and only then memory usage is growing. Also switching tabs is instant.

That is probably what bug 542158 is saying.

Can confirm fix of about:memory in FF9 (linux).

Is that after going through the whole slideshow, or after just loading the page?  Firefox aggressively loads images (bug 542158), so we know its usage at the beginning will be more than Chrome.  The question is: After you view all the photos in the slideshow, what's Chrome's memory usage?
My numbers are with just loading the page, not going through the slideshow.
It may be true that when using the slideshow the memory is really needed (comment 13) and it can't be helped. The problem here is that when a visitor comes to this page he sees a short page (about 2 screens high) with 1 big image and some small ones. Then firefox takes ~1GB RAM and if he has some othe tabs already open, FF may easily get killed by the OS at 2GB limit. If not, he may see a slow system. The problem is, he may not even notice the slideshow is there (it took me also some time), so he will not understand why FF takes so much memory. In other browsers the first load is fine, with low memory usage. Only if the users finds the slideshow and starts to use it the memory gets allocated. It this point there is a higher chance the user will understand the problem why the browser is taking so much memory. He saw there are many images being decoded. So this can be taken as an issue of predictable and understandable behaviour of the browser.

This depends on decode on draw, bug 542158.  I'm donating this bug's [MemShrink] tag to that one.

Er, decode on draw is bug 573583.

No longer depends on: 542158
I just load fist page (no slide show) with FF 8 and Chrome, in WinXP 32, sp3
FF 8 (safe mode): 951,988 K
Chrome: 104,032 + 53,468 + 29,324 + 18,488 + 18,940 + 9,168 = 233,420K

here after view all photos:
FF 8: 1,004,624K
Chrome: 112,332 + 54,628 + 34,592 + 19,068 + 18,944 + 9,200 =
Turns out this isn't a decode-on-draw issue, but a more general we-suck-at-images issue.
Depends on: image-suck
No longer depends on: 573583

With FF14, CSet:babbc38b7f52, Fresh Profile, No addons, I am not getting anything huge memory usage, here is the about:memory output:

Confirming!
When visiting the page, the images are NOT decoded beforehand. I must click on the slideshow to see some of them and only then those needed are decoded. If I then stop and leave the tab unused, the memory is released after a while (looking at the gfx-surface-xlib number).
With bug 689623 fixed, I thought this might have improved.  First I tried a pre-689623 build, but I couldn't reproduce the problem on my Mac, even after I clicked through all 94 pictures in the slideshow.  Resident memory consumption didn't exceed 250 MiB, and the "explicit/images/content/used/uncompressed-heap" numbers didn't go above a few 10s of MiBs.

Does this site still cause problems for other people?
We made some improvements since the last previous activity in this bug and bug 689623, like not locking images that aren't in the DOM and images that don't have layout frames created for them. One of those could have solved this.
The page seems to work fine now for me.

Yes, now it works fine. (FF 19)
