Disk expansion

Assuming you follow the tutorial in the video to expand /dev/sda3 and get an error saying read-only:

mount | grep sda3

Shows I have two mount points here:

/dev/sda3 on / type ext4 (rw,relatime,errors=remount-ro)
/dev/sda3 on /var/snap/firefox/common/host-hunspell type ext4 (ro,noexec,noatime,errors=remount-ro)

Need to remount these two mount points (I'm not entirely sure this is correct, forgot a bit):

sudo mount -o remount,rw /dev/sda3/
sudo mount -o remount,rw /dev/sda3/var/snap/firefox/common/host-hunspell

Then reopen gparted and follow the video steps again
