Firefox 3 speed tweaks
I've come across several speed tweaks for firefox that I have not know about before. These are probably not new to some of you, but I'm hoping someone can get some good use out of them.
Pipelining
Firefox will open several HTTP requests for each webpage with pipelining enabled. Therefore, if you have access to a high bandwidth internet connection, you should be able to download pages faster. In the location bar, go to "about:config". Find the following values:
network.http.pipelining
network.http.pipelining.ssl
network.http.proxy.pipelining
and make sure they are set to true.
Next, you can also change the default number of connection requests:
network.http.pipelining.maxrequests
The default is 4. You should be able to see a performance boost (depending on your connection bandwidth) with values between 4-32. Make sure you don't set the value too high.
Initial Paint Delay
Again, from the "about:config" page. Right-click anywhere inside the page and from the popup menu choose "New->Integer" and create the following name:nglayout.initialpaint.delay
The value you should set to 0. This ensures that the webpage will start being drawn on the screen without any delay (by default Firefox has a delay so it can render more of the webpage at once).
Turn off phishing protection
This setting is Firefox 3 specific. With the introduction of FF3, by default every http request is checked against a database of phishing links. If you are not a newcomer to the Internet and you are aware that you should not give away credit card information to "paypol.com" then this tweak could help a lot: On every single request, firefox sends a request to google to find out if a link is a possible phishing scam. Next it also adds an entry to an sqlite database found in your mozilla profile directory (at the time of writing, my database was already a 100mb completely unnecessary file!). Here's the fix if you feel brave enough to take on the Internet without mozilla and google's guiding hands:- Preferences -> Security -> "Tell me if the site I'm visiting is a suspected Attack site" [OFF]
- Preferences -> Security -> "Tell me if the site I'm visiting is a suspected forgery" [OFF]
