Firefox Tweaks!

post #1 of 11
Thread Starter 
Throughout this guide I will be referencing Firefox's configuration. This can be accessed by typing 'about:config' in the the address bar.


Memory caching for faster page loads
This caches pages that are visited often so they load faster.

Instructions:

  1. Enter configuration
  2. Change browser.cache.disk.enable from true to false (Right Click>Toggle)
  3. Right Click Anywhere>New>Integer
  4. Enter the preference name: browser.cache.memory.capacity
  5. Enter the value: -1
  6. Make sure that browser.cache.memory.enable is set to true
Firefox will allocate the cache as the following:

RAM : Cache
512 MiB : 14 MiB
1 GiB : 18 MiB
2 GiB : 24 MiB
4 GiB : 30 MiB
8 GiB+ : 32 MiB

Reduce RAM usage when Firefox is minimized (Windows Only)
This is a feature that Windows has that when a program is minimized for a long period of time, it will swap the memory the program is using to the disk. This greatly reduces RAM usage, but this will also decrease the performance of Firefox, ONLY when it is being restored.

Instructions:
  1. Enter configuration
  2. Right Click Anywhere>New>Boolean
  3. Enter the preference name: config.trim_on_minimize
  4. Enter the value: true
Fix slow page loads/wrong images/swapped images issues
Around the web there have been guides that state they can speed up Firefox's page loading time. Most often this involved changing the value of
network.http.pipelining.maxrequests to a high number. There is a problem with this because the values should ONLY range from 1-8. Having it any higher, people may find that pages will load slower, load incorrectly or have images swapping/appearing where they are not supposed to.
IF YOU HAVE NOT CHANGED
network.http.pipelining.maxrequests THIS DOES NOT APPLY TO YOU! You should leave it at the default value, or if you'd like (and if you notice a difference) you may change the value to 8, otherwise DO NOT CHANGE THIS VALUE!

Instructions:
  1. Enter configuration
  2. In the filter at the top of the page type network.http.pipelining.maxrequests
  3. Right Click>Modify
  4. Change the value between 1 to 8. 1 Disables pipelining.
  5. Quote:
    Higher values will cause a delay before the first request completes but will make the last request complete sooner. Higher values will also cause more of a delay if a connection fails. Source: http://kb.mozillazine.org/Network.http.pipelining.maxrequests
Enabling Pipelining
From HTTP 1.1 and onwards, multiple requests can be sent for a page to load before any are received. This reduces network load/page loading times over high latency connections. BEWARE: Some servers do not support this value! Therefore this may reject the connection or break the web page. If this happens often, then you should disable this setting.

Instructions:
  1. Enter configuration
  2. In the filter (at the top of the page) type network.http.keep-alive and check that it is set to true
  3. In the filter type network.http.version and check that this is set to 1.1
  4. In the filter type network.http.pipelining
  5. Right click>Toggle (so it is set to True)


I will continue to add tweaks as I go along. Enjoy for now wink.gif

I realize you have "Beware" next to some of the settings, but you should include somewhere in this guide that editing anything in about:config without proper directions can & will cause issues/errors.

Other than that, cool guide.

Very nice guide I suppose smile.gif
Seems very redundant though, I can do all of this with an excellent firefox addon called Fasterfox Lite. Much easier. I have it listed in my own Firefox optimization article (sig)

Well the first time they enter about:config it gives a warning tongue.gif

ive got browser.cache.memory.enable set to false as waterfox's cache and all files in roaming and local are on a ramdisk so i wouldn't think there would be an improvment in having it enabled
post #6 of 11
It's basically the same thing as a RAMdisk cache
Except you don't have to deal with creating an actual RAMdisk and all

Cool guide I use Firefox 24/7 so I might try some of these tweaks out to see how they work for me.
