I am using Firefox installed through snap (Ubuntu 23.04, snapd/lunar-updates,lunar-security,now 2.59.1+23.04ubuntu1.1 amd64). I have removed all but latest versions due to lack of disk space.
Installed should be only the latest version as reported by snap:
sudo snap list --all | grep firefox
firefox 117.0.1-2 3131 latest/stable/… mozilla**
But then I have noticed that there are still old versions of firefox on disk:
ls -lh /var/lib/snapd/snaps | grep firefox
-rw------- 1 root root 243M maj 12 12:07 firefox_2645.snap
-rw------- 1 root root 245M jun 8 17:28 firefox_2748.snap
-rw------- 1 root root 245M jun 19 16:34 firefox_2760.snap
-rw------- 1 root root 245M jul 10 15:43 firefox_2880.snap
-rw------- 1 root root 238M avg 3 21:53 firefox_2952.snap
-rw------- 1 root root 238M avg 15 18:47 firefox_2987.snap
-rw------- 1 root root 237M sep 13 12:34 firefox_3131.snap
and
ls -lh /var/lib/snapd/seed/snaps/ | grep firefox
-rw------- 1 root root 239M okt 20 2022 firefox_1969.snap
Could I simply remove old version files manually or are they are needed for some reason?
Generally I have noticed difference if I run snap list –all or list files in /var/lib/snapd/snaps, there are some versions more left on disk.

You can safely remove all but the latest two versions of the firefox snap package from
/var/lib/snapd/snaps/in order to free up disk space.The latest two versions of the firefox snap package to keep are listed in your question as follows:
Or show the files to keep more simply with
cd /var/lib/snapd/snaps/ && ls | grep firefox
