I got an out of memory error with 32 bit linux. I know this happens with
32 bit windows, but I didn't expect it with linux pae. But I have 2G RAM
plus 3G swap so that's 5G, maybe not enough for Seamonkey? I have now
increased swap using a swapfile so I have 10G....

Happens fast with media playback or sites using complex scripting / css uBlock
and NoScript help but even then 2GB is not enough. Swap might not help here
too. OOM is oom.

Aggressive NoScript can keep things under control, so that you can have
a couple of windows with a few tabs in each as well as mail/news with
IMAP+local folders/newsgroups/RSS feeds, Since the mail/news is in the
same process*, too much of that limits the browser, and vice versa.

As an example, this is being posted from a tiny HP "WindowsBook" with
~10 open windows including a SM browser window with 16 tabs, a mail/news
window and a message window (and plainly a message compose window ATM!):

Processor : Intel(R) Celeron(R) CPU N2840 @ 2.16GHz
Memory : 1952MB (1098MB used)
Machine Type : Notebook
Operating System : Debian GNU/Linux 12 (bookworm)

There is a 3GB swap^H^H^H^Hpagefile, mostly for hibernation, on its 32GB
eMMC. SM is using 2.9GB of VM and ~20% CPU (about twice XFCE TaskManager).

Media playback is possible, but youtube-dl/yt-dlp + mpv is much better
for supported sites.

If SM is crashing on OP's system with one or two tabs, that would be
surprising.

Improved support for new JS syntax and components will increase website
compatibility probably at the cost of higher resource demands.

*When Opera (pre-WebKit) had a built-in mail/news function, it was
possible to set up two configurations, so that Opera browser ran in one
process and Opera mail/news in another. Maybe Mozilla/SM is too tightly
integrated for that unless you go the full FF/TB route.

Is this an ancient machine?
My first 64-bit machine was in 2007 and has long since bitten the dust
(an Intel Core Duo laptop), so I'm wondering why you don't have
something more current. This is being written on a Ryzen 5 4600G with
16G memory.

I don't watch videos with SM, and I have Javascript disabled. As far as
I remember I was just looking at email. I have had both Firefox and
Chromium running at the same time on this computer without trouble. I am
continuing to experiment....

I have written a program which allocates memory.

total used free shared buff/cache available
Mem: 2.0Gi 1.9Gi 125Mi 696Ki 169Mi 87Mi
Swap: 10Gi 2.8Gi 8.2Gi

It has used up 2.8 gigabytes of swap space before failing to
allocate. But it didn't crash.

I guess Seamonkey is trying to allocate memory faster than the system
can supply it. Why doesn't it wait for a bit then try again?

I find Thunderbird works OK, and so does Firefox, and Chromium, but
Seamonkey crashes even with 10G of virtual memory. I think that must be
a bug. Tried to run it with gdb but of course it didn't crash then. :/
