683284 - (image-suck) [meta] Images suck the snap out of Firefox (memory, flicker, decode/discard heuristics)

Status: NEW

(Core :: Graphics: ImageLib, defect)

Description

[Jeff Muizelaar [:jrmuizel]]

This is tracking bug for all of the imagey things we do worse at than other browsers.

Comment 1

[Jeff Muizelaar [:jrmuizel]]

I'd like this bug to only address bugs where our behaviour is a clearly wrong compared to other browsers. It's not clear from 124608 what the problem actually is.

My Firefox crashes almost 20-30 times during a working day because of imagery memory consumption. I miss the good behaving Firefox before. I can hardly recall when is this happening, but it seems that 7.0 or 8.0 may be a start.

How do you know it's the memory for images that is the cause?  The only changes to image memory handling that I'm aware of lately should have reduced the memory usage.

Thanks for your correction, and I do not know indeed if it's a consumption problem or not.

But there is indeed problem in Firefox because other related bugs has direct me here.

Not much change since 4.0 on image heavy site, the good old days your mention was 3.6.

And 32bit Windows system is somehow worse, because an application can have only 2GB address space and Firefox will crash when it consumes about 1.5G RAM..

This is a metabug, for tracking multiple separate problems; it is not for discussing any one issue.  If you have steps which reliably cause you to crash, please file a separate bug and CC me on it; I'll follow up.

Bug 659220 which was marked duplicate of bug 660577 which was marked duplicate of this raised a question that I don't see in the remaining live bugs on image consumption. Specifically that DOM/JS image objects are small, even though the images they are holding on to may be large. Since they are small they may not trigger a JS GC, leaving the image layer thinking those images are still in use.

This bug is related huge size about "images/content/used/uncompressed"?
It can reproduce easily in flickr.com slideshow.

Step 1. open this url in 3 more tabs.

Step 2. click "play button"

Step 3. 1 hour later, check about:memory

It's a BIG problem in mobile or embedded linux environments.
Thanks,

That's roughly Bug 679775, and the fix is Bug 683290.

Wouldn't these qualify for blocking this bug too?
