Firefox Add-ons

Must-have firefox add-ons:

• Xmarks (formerly Foxmarks): A very easy to use bookmark synchronization tool. Extremely useful if you use multiple computers. Keeps a version history of your bookmarks, can synchronize automatically upon exiting firefox, and can keep multiple bookmark profiles (work, home, etc.).
• AutoCopy: Copies the selected text to clipboard. Saves an incredible amount of time and frustration during copy-paste operations.
• CustomizeGoogle: Tired of all the ads on google, or want to change how clean gmail looks, then this is perfect for you.
• Adblock Plus: Ads are gone. I cannot surf the Internet without this add-on; pages look really bad and packed without it.
• Personal Menu: IE- or Chrome-like menu instead of the menu bar on top. Saves space. Note, if you just want to gain some screen real estate, you can use the lighter extension named Hide Menubar. In both, pressing "Alt" reveals the menu bar.
  

I try to keep my add-ons to a minimum to keep firefox fast. Comment down if you have other favorites and suggestions...
