It seems like the memory leaks in 2.53 are worse than in 2.49. I am now using SM x64 instead of x86 - don't know if that makes a difference. I can get up to 1.5GB fast, and SM starts slowing down noticeably. Closing all tabs (but one) doesn't release much of the memory.

I've tried to narrow it down to a site or add-on, but can't determine a single cause. I'm using only uBlock and web tools add-ons (which I've had for years). The only time I actually saw memory clearly increase is when playing a video, like on Yahoo's page.

Anyone else seeing this or have a good way to debug. It is really bad - I have to shutdown SM multiple times per day.

Have you tried starting in Mozilla Safe Mode?
If no improvement using Safe Mode, do you have the same problem if you create a new profile and test it with no extensions or non-default themes installed?

Well I can get to 3 or 4GB fast on some websites. They just need to use a lot of javascript or html5. Going to 1.5 GB is no memory leak. The question is if it is actually released later.

Check about:memory to see if something sticks out. Also use uBlock Origin and Noscript to block junk. This helps tremendously.

Depending on what I do, where I go, I can quickly get SeaMonkey (browsers in general) to a point where they simply eat memory, &/or to the point where usability declines - significantly, & the only viable option is to restart.
(In my case, most often this occurs when visiting video sites.)

SeaMonkey, is my stable, do everything, work the way I want to work, work browser.
But I also understand its limitations on today's "crap" websites.
Some sites simply do not work as well on SeaMonkey as they do on other browsers.

So for "crap" sites, I tend to use (cough) FF - which is often better behaved on crap sites, or can more efficiently use more memory before becoming over-tasked.
(Actually, I don't use FF, I simply throw crap at it.)

If I still decide to use SeaMonkey in such a way, if I am running into sites where memory is rapidly ramped up, where performance rapidly declines, I restart SeaMonkey & let it have another go at things.

I second therube's experience. Media is certainly one culprit. It does seem to be a bit unpredictable and hard to pin down.

Safe mode doesn't make much of a difference. I opened only Yahoo! and let it set for 8+ hours. It started out lower (~220MB) than with my profile (~320MB), but it still ate it up to 800MB. I opened a new tab it and dropped to ~320MB.

Usually the memory does not release, and that is why I have to shut down. I wouldn't care so much if performance didn't drop off at a mere 1GB. 3-4GB is just ridiculous for a web browser, IMHO. (You got 500 tabs open or something?)
