[Bug 1899309] Re: firefox leaks memory and crashes computer (lack of swap)

[Olivier Tilloy]

Thanks for the report Daniel.

Unfortunately browsers in general are becoming ever more memory-hungry,
this is a general trend that doesn't play well with legacy systems with
a modest amount of RAM (although the 12GB that you mention should be
plenty).

There is no silver bullet, but here are a few suggestions that could help.
The "about:memory" page in firefox has a "Minimize memory usage" button that could help in some situations.
If you tend to have a large number of tabs open, there are extensions that can suspend the ones in the background to reclaim used memory.
Lastly, the nohang package suggested by Oibaf may be a good idea. It will kill renderer processes early, before your system starts swapping.

If you are seeing actual memory leaks in firefox, I encourage you to
report them upstream at
https://bugzilla.mozilla.org/enter_bug.cgi#h=dupes%7CFirefox.

I'm closing this bug as it's not really actionable, and unlikely Ubuntu-specific.
Feel free to re-open with additional data if you think there are Ubuntu-specific problems that should be addressed.
