[xubuntu-users] Firefox using memory while session is disconnected/locked

[Václav Haisman]

Hi.

Recently, like last month, I have been observing odd behaviour of
Firefox when I disconnect from / lock the session.

When I return home after work, I log back in and the root Firefox
process uses, say 9 GiB of RAM. The Firefox windows are unresponsive.
When I look at process list in top, I can that the main Firefox process
is slowly returning memory. Once it is finished, around 1 GiB RSS, all
of the Firefox windows start responding again.

There is no swapping involved. I have 64 GiB of RAM.

It appears to be leaking memory when the session is locked/disconnected
and it GCs it when I return and log back in.

This is with 20.04.1. I am just wondering if anyone else is seeing the
same symptoms.
