LeechBlock is a simple productivity tool designed to block those time-wasting sites that can suck the life out of your working day. (You know: the ones that rhyme with ‘Blue Cube’, ‘Pie Face’, ‘Space Hook’, ‘Hash Pot’, ‘Sticky Media’, and the like.) All you need to do is specify which sites to block and when to block them.

You can specify up to six sets of sites to block, with different times and days for each set. You can block sites within fixed time periods (e.g., between 9am and 5pm), after a time limit (e.g., 10 minutes in every hour), or with a combination of time periods and time limit (e.g., 10 minutes in every hour between 9am and 5pm). You can also set a password for access to the extension options, just to slow you down in moments of weakness!

orbutton provides a button to easily enable or disable the browser’s use of Tor

Torbutton is a 1-click way for Firefox users to enable or disable the browser’s use of Tor. It adds a panel to the statusbar that says “Tor Enabled” (in green) or “Tor Disabled” (in red). The user may click on the panel to toggle the status.

If you change proxy settings, all chages will be reflected in the statusbar.

Some users may prefer a toolbar button instead of a statusbar panel. Such a button is included, and one adds it to the toolbar by right-clicking on the desired toolbar, selecting “Customize…”, and then dragging the Torbutton icon onto the toolbar. There is an option in the preferences to hide the statusbar panel (Tools->Extensions, select Torbutton, and click on Preferences).

Newer Firefoxes have the ability to send DNS resolves through the socks proxy, and Torbutton will make use of this feature if it is available in your version of Firefo
