Ok im going to try and do something useful for once.
Im going to give you links to firefox and addons that will grant you security on the internet, without sacrificing speed using proxys.
First off, get firefox: http://www.mozilla.com/en-US/firefox/
Once installed download these add-ons, I will go into detail as to what they are;
TabRenamizor, this is simply put, a tab re-namer on firefox https://addons.mozilla.org/en-US/firefox/addon/2987
HideBad, this tool closes the tabs on firefox and stores them in memory, at the push of a button, and replaces all the open tabs with your homepage, the closed tabs can be retrieved after what ever event caused you to close them first off. https://addons.mozilla.org/en-US/firefox/addon/1052
KeyscramblerPersonal, this tool will encrypt ALL keystrokes made on your computer while active, this is great because it helps provide security from keyloggers from unknown links. https://addons.mozilla.org/en-US/firefox/addon/3383
CSlite, simply this blocks cookies FROM all sites unless specified which sites not to block, another great tool to keep your security in check
Temporary Inbox, I LOVE this addon, it creates random disposible emails so you can anonymously sign up for sites, amazing add-on. and can get a lot of use.(this one is meant for non malicious purposes, such as if you want to sign up for sites were you dont want your email on) https://addons.mozilla.org/en-US/firefox/addon/2650
Distrust, this is a addon that gives firefox private browsing, you turn it on and when you are done, turn it off and al your history will be deleted, this also works if you alt + f4 out of page, it will count that as turning off. VERY USEFUL. https://addons.mozilla.org/en-US/firefox/addon/1559
Track me not, this is a really simple addon, basically it will hIde what you search for on google, yahoo, live, etc. https://addons.mozilla.org/en-US/firefox/addon/3173
Pretty good, if your looking for something like a torrent or illegal game crack.
There you have it.
I DO NOT CONDONE USING THESE FOR ILLEGAL OR MALICIOUS MEANS, THESE ARE MEANT AS PERSONAL SECURITY, WHAT YOU DO WITH IT IS YOUR OWN BUISINESS, I'M NOT AT FAULT FOR ANYTHING YOU MAY DO.
