Customize any and every webpage!

First get the GreaseMonkey Firefox extension.
Then write your own script or install some of the hundreds available at UserScripts.org.

Here are my recommendations:
User Scripts Search Sorting - With Install Rate improves the sorting on userscripts.org making it easier to find scripts. Use it to toggle between 'install rate' or 'installs'

After a secure login gmail defaults to HTTP so I got tired of manually switching it back into HTTPS. Secure-em-All automagically secures many webmail sites.

Sourceforge Direct Links saves time with direct download links from sourceforge projects. But save yourself some time and do not install either cleaner layout scripts because they no longer work.

Download Video allows you to download videos from youtube, gvideo, and myspace.

Textarea Backup w/Restore Buttons automatically backs up the text you type so you'll never accidentally loose another email. It has a restore button so it's better than the script that automatically restores text [when you do not want it to].

You'll find tons more for the sites you use and dont worry you can turn greasemonkey or any script on/off with a click of a button.

View the source before you install each script just to verify it doesnt do anything sketch and I hope you find it as useful as I do.

View blocked websites

To circumvent internet filters you must use a web proxy.

The best way to do this is to use the tor network.
tor, is free, opensource and developed by the EFF, so it's trustworthy and safe to use.

tor on its own is tricky to setup so i recommend a very easy to use package called vidalia which installs tor and other necessary apps.

http://www.vidalia-project.net/download.php

this will installed tor, privoxy, and the tor button for firefox.

once installed, filter-free surfing is as simple as clicking the'Tor Enable' text button in the bottom right corner of firefox.

if you dont already surf with firefox, download it here

if you need to install the tor button then download it here
