Firefox Speed Up 3 Hacks

Double Your Internet Browsing Speed

Firefox RAM Memory Bug. Lets get it straight. It’s not a bug. It’s part of the cache feature. This ‘feature’ is how  the pages are cached in a tabbed environment.

To improve performance when navigating (studies show that 39% of all page navigations are renavigations to pages visited less than 10 pages ago, usually using the back button), Firefox implements a Back-Forward cache that retains the rendered document for the last five session history entries for each tab.


This is a lot of data. If you have a lot of tabs, Firefox’s RAM memory usage can climb dramatically. It’s a trade-off. What you get out of it is faster performance as you navigate the web.

Now a lot of us have found the ’secrets’ on how to manipulate settings in “about:config” to drop the memory usage as long as possible and to increase the speed at which Firefox loads sites.


Reduce the amount of RAM Firefox uses for it’s cache feature

How to :
1. Type “about:config” (no quotes) in the adress bar in the browser.
2. Find “browser.sessionhistory.max_total_viewer”
3. Set it’s value to “0“;(Zero)
Increase the Speed in Which Firefox loads pages

1. Type “about:config” into the address bar and hit Enter.
(Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.)

2. Alter the entries as follows:
Set “network.http.pipelining” to “true”
Set “network.http.proxy.pipelining” to “true”
Set “network.http.pipelining.maxrequests” to some number like 10.

This means it will make 10 requests at once.

3. Lastly, right-click anywhere and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0“;.(Zero)

This value is the amount of time the browser waits before it acts on information it receives. If you’re using a broadband connection you’ll load pages faster now.
Optionally (for even faster web browsing) here are some more options for your about:config (you might have to create some of these entries by Right Click –> New– > Interger or String

network.dns.disableIPv6: set “false”
“content.notify.backoffcount”: set “5“; (Five)
“plugin.expose_full_path”: set “true”.
“ui.submenuDelay”: set “0; (zero)
Reduce RAM usage to 10mb when Firefox is minimized:

Drop Firefox’s RAM usage down to 10 Mb when minimized:

1. Open Firefox and go to the Address Bar. Type in about:config and then press Enter.
2. Right Click in the page and select New -> Boolean.
3. In the box that pops up enter “config.trim_on_minimize”. Press Enter.
4. Now select True and then press Enter.
5. Restart Firefox.

This will make your web browsing with Mozilla Firefox 2-3 times faster and easier.Goodluck.
