8 Must-Have Twitter and Facebook Add-Ons

By no means are Twitter and Facebook perfect: You might wish that Facebook made it more intuitive to hide FarmVille or certain status updates. Or, maybe you wish that Twitter would introduce a new feature like nested tweets. Good news: For many of these website tweaks or suggestions, there’s likely to be a script you can download to fit the bill.

Here are my top eight picks for Facebook and Twitter add-ons. Many of these solve common user gripes (such as not knowing to what site shortened URLs will bring you on Twitter). Some, like “Facebook Fixer,” enhance the site and allow you to customize it beyond standard options. Do note that most of these scripts require that you first download Greasemonkey, and not all are compatible with every browser, so be sure to check the requirements before you download a script.

1. Facebook Fixer.

This script lets you customize your Facebook account and offers many features that are enabled by default, but can be enabled or disabled independently. Some of these features include: larger profile and album pictures; homepage customization where you can hide independent sections such as pokes, suggestions and “connect with friends”; and calendar integration, which includes a link on each profile that synchs birthdays with Google Calendar, or the option to export a file with all your friends’ birthdays, which can be imported into sites such as Google Calendar, Yahoo, Apple iCal, Microsoft Outlook and more.

2. Facebook Purity.

The Facebook Purity script cleans up your homepage and removes all newsfeed items from third-party games such as Mafia Wars and FarmVille, and zaps announcements on who’s become friend with who, who’s attending a certain event, who joined a group and who became a fan of something. Optional items you can block include: comments on a status, photo, photo album or link; tags in a photo or photo album; and event postings.

3. Unfriend Finder.
