Check which files are opened by Firefox then sort by largest size.

lsof -p $(pidof firefox) | awk '/.mozilla/ { s = int($7/(2^20)); if(s>0) print (s)" MB -- "$9 | "sort -rn" }'

Just refining last proposal for this check, showing awk power to make more complex math (instead /1024/1024, 2^20). We don't need declare variable before run lsof, because $(command) returns his output. Also, awk can perform filtering by regexp instead to call grep. I changed the 0.0000xxxx messy output, with a more readable form purging all fractional numbers and files less than 1 MB.

Sample Output

41 MB -- /home/tzk/.mozilla/firefox/default/urlclassifier3.sqlite
6 MB -- /home/tzk/.mozilla/firefox/default/places.sqlite
3 MB -- /home/tzk/.mozilla/firefox/default/XPC.mfasl
2 MB -- /home/tzk/.mozilla/firefox/default/extensions/writearea@writearea.com/chrome/writearea.jar
2 MB -- /home/tzk/.mozilla/firefox/default/extensions/writearea@writearea.com/chrome/writearea.jar
2 MB -- /home/tzk/.mozilla/firefox/default/extensions/{4BBDD651-70CF-4821-84F8-2B918CF89CA3}-trash/chrome/febe.jar

Check which files are opened by Firefox then sort by largest size.

Check which files are opened by Firefox then sort by largest size (in MB). You can see all files opened by just replacing grep to "/". Useful if you'd like to debug and check which extensions or files are taking too much memory resources in Firefox. Show Sample Output

FFPID=$(pidof firefox-bin) && lsof -p $FFPID | awk '{ if($7>0) print ($7/1024/1024)" MB -- "$9; }' | grep ".mozilla" | sort -rn

What Others Think

Nicely done, I would use "lsof -c firefox" in place of "lsof -p $(pidof firefox)" to tune it a little more.
