https://fixmynix.com/speed-up-firefox-with-ram-cache-and-tmpfs-linux/

--------------------------------------------------------------------------------

-- go to firefox -> about:config


    Search for browser.cache.use_new_backend , if the value is 0 , modify it to 1 , this makes the caching efficient.
    Search for network.http.pipelining.ssl toggle it value to true .
    Search for network.http.pipelining , toggle the value to true .
    Search for network.http.proxy.pipelining , toggle its value to true .
    Search for network.http.pipelining.maxrequests , modify the value , set any thing above 100 , like 120 .
    
--------------------------------------------------------------------------------

-- move the cache to RAM

    go to firefox -> about:config
    
    Search for browser.cache.disk.enable  in the filter bar, toggle the value to false , this will disable cache to disk.
    Now it is the time to enable cache to RAM, search for browser.cache.memory.enable , if the value is true leave it else toggle it to true.Now assign how much memory could be used as RAM cache, search for browser.cache.memory.capacity , if not found create it. (I set it to 358400)
    
--------------------------------------------------------------------------------
    
-- clear all cache and cookies 

--------------------------------------------------------------------------------

-- backup default profile data

cd .mozilla/firefox/
cp -a nba79gxr.default/ nba79gxr.bac
-- nba79gxr must be cnahged with the profile name

--------------------------------------------------------------------------------

-- mount the tmpfs on profile folder

sudo nano /etc/fstab

    put in:
# tempfs - firefox 
tmpfs /home/geo/.mozilla/firefox/nba79gxr.default tmpfs size=256M,user,exec,uid$

--------------------------------------------------------------------------------

-- Now mount the tmpfs at profile directory , i.e. at /home/$USER/.mozilla/firefox/profile_name.default and copy all the backup data to the default profile folder.

sudo mount -a
cd ~/.mozilla/firefox/
cp -a nba79gxr.bac/* nba79gxr.default/

--------------------------------------------------------------------------------

-- sync any changes to the profile folder with the backup folder

sudo pacman -S rsync
sudo nano /usr/local/bin/ff_profile_sync

-- and put in

#!/bin/sh
cd /home/geo/.mozilla/firefox/
if test -d /home/geo/.mozilla/firefox/*.default;then
if test -d /home/geo/.mozilla/firefox/nba79gxr.bac;then
rsync -a --delete /home/geo/.mozilla/firefox/*.default/ /home/geo/.mozilla/firefox/nba79gxr.bac/
fi;fi
