How to speed up Firefox

There is an extension to put Firefox to the max speed: Fasterfox (click to download from Mozilla addons) but we can do the same or even better by hand following these steps:

* on Linux: if we usually don't surf on oriental website we can disable Pango
edit sudo nano /etc/environment and append this row: MOZ_DISABLE_PANGO="1"


Note: if you are going to use Fasterfox to make optimization, after Fasterfox optimization jump directly to step 4.

1. On the keyboard press control+n a new Firefox window will open, into the address bar type of the new windows type "about:config" and then press enter;
This will bring up a long list of Preferences. You can filter them by typing: network.http. and so on.
2. Now we are ready to change some values, like below:
browser.turbo.enabled: true
network.dns.disableIPv6: true
network.http.max-connections: 48
network.http.max-connections-per-server: 24
network.http.max-persistent-connections-per-proxy: 12
network.http.max-persistent-connections-per-server: 6
network.http.pipelining.firstrequest: true
network.http.pipelining: true
network.http.pipelining.maxrequests: 30
network.http.proxy.pipelining: true
browser.history_expire_days_min: 3

Do not set network.http.pipelining.maxrequests to a high value.
If you set a high value ( 32 ) some servers will ban you because your visit will seem like a "flood" attack.
If you are afraid of this set network.http.pipelining.maxrequests to 8.

3. Now we must create a new integer value; right click the mouse button and select New -> Integer.
Keyin the new parameter name "nglayout.initialpaint.delay".
Set the value to 0 (zero).
We must also set the "browser.turbo.enabled" value to true

4. To reduce Firefox RAM allocation

a) Create a new boolean value: config.trim_on_minimize set it to true

b) set the browser.cache.memory.capacity to a fixed value:
if you have 256 MB RAM -> 14336, 512 MB RAM -> 22528, 1 GB RAM -> 32768

c) set the browser.sessionhistory.max_total_viewers to 0

d) Optionally change the image.animation_mode to none

Fron Menu -> Tools -> Options...

* Set a low value for the disk cache (less of 50 MB)
* If you don't use Java disable it
* Don't use RAM eater extensions. Don't install a lot of extensions. Remove unused extensions.
* Clear the history of downloaded files.

5. Restart Firefox. If you're using a broadband connection you will load pages much faster.

6. If you want to put all back, as the original state, you can right click on the single modified bold parameter.

7. Stop unwanted advertising with the extension Adblock Plus and keep it update with Adblock Filterset Updater

8. To preload Firefox to speedup the starting process we must use Firefox Preload
