Safari 4.1.1 hanging and needing 5-step restart program.

Question

I use Safari 4.1.1. It has always occasionally hung but hanging has become increasingly frequent during the last year--often 3 or 4 times within an hour or two. I have installed all updates as they have appeared. In order to close Safari and restart it I do the following:
1. Force Quit Safari (only once or twice has this not worked; I have then had to shut down using the power button).
2. Restart Safari by clicking its icon in the Task Bar, at which time my home page (Google) does not load beyond a blank, white screen (no logo, etc.). I then:
3. Reset Safari, checking off all items for resetting. Again, Google will not load, so I:
4. Quit Safari using Quit under File.
5. Restart Safari by clicking its icon in the Task Bar, at which time it starts and loads fine. Then, I'm off surfing, just waiting for the next time it hangs all.
HELP!

Welcome to the forums!
Do you have enough RAM? Less than 1GB can cause slowness. Is your hard drive too full? Less than 15%, or 15GB, of free space can also cause slowness.
If you use a router, does it have the latest firmware installed? Safari 5 introduced 'DNS Prefetching' (Safari looks up the addresses of links on webpages and can load those pages faster) which could strain some routers or modems producing a 'latency' in page loading. This was fixed in Safari 5.0.1, but you may see a benefit from getting a faster router or modem.
Adding DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security:
If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
208.67.222.222
208.67.220.220
(You can also enter them if you click on Advanced and then DNS)
Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:

If your computer is part of a network: please refer to this page: http://www.opendns.com/start/bestpractices/#yournetwork and follow the advice given.
(An explanation of why using Open DNS is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 /
Open DNS also provides an anti-phishing feature: http://www.opendns.com/solutions/homenetwork/anti-phishing/ )
Wikipedia also has an interesting article about Open DNS:
http://en.wikipedia.org/wiki/OpenDNS
Whilst in System Preferences/Network you should also turn off 'IPv6' in your preference pane, as otherwise you may not get the full speed benefit (the DNS resolver will default to making SRV queries). If you want to know what IPv6 is:
This is Apple's guidance on iPv6:
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8708.html
Click on Apply Now and close the window.
Restart Safari, and repair permissions.
Also, third-party add-ons created for a previous version of Safari may cause problems:

If that didn't do it, then try this as well:
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
form values
download.plist
Then go to Home/Library/Preferences and delete
com.apple.Safari.plist
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.
