iMacros – iMacros is a free Firefox plugin. It basically lets you record any sequence of actions you do inside of Firefox. These can be saved as macros to be played back later. This is perfect for automated simple, repetive tasks.

uBot – The UBot development environment was specifically created to make web based bots. It’s easy for non programmers to pick up, yet it is still very powerful. Can deal with captchas, proxies, and scrapes web pages with ease. You can also compile your bots to give away or sell to others.

WinAutomation – Unlike the other tools, WinAutomation can automate more than just your web browser. It can actually automate Windows itself. It has macro recording capabilities like iMacros and it also supports flow control, conditionals and loops like uBot.

Using automation tools can save you both time and money. Why buy a tool like Bookmarking Demon when you could create your own bot with UBot that can do the same thing. Anyway, check these tools out and see if you can add them into your everyday workflow.
