With Apple's new support for Safari Extensions, people will now be able to install small widgets to enhance their Safari experience, very much like Dashboard can bring tools, games, and other enhancements to the OS X desktop. Along with the release of Dashboard, Apple provided developer tools and reference materials for creating widgets, and then created a widget library so people could easily download them.
With the release of Safari Extensions, Apple is providing a similar path with the availability of developer tools for these extensions. If you are a developer, you can join the Safari Developer Program and use these resources to create your extensions. However, the one aspect of these widgets that is missing is an easy way for people to browse through available extensions.
Apple will undoubtedly create a widget gallery of sorts, similar to those provided by Google for Chrome, and Mozilla for Firefox. Until then, I have only been able to find a few reasonable download sites that are focused towards providing Safari extensions for users.
SafariExtensions.org seems to be the most developed options so far, which provides submission and distribution options for Safari Extensions. So far it has about fourty different extensions avaialbe for download, and has options to list them by type, date updated, or popularity. Others available are a small Safari Extension blog, and a website called "Pimp My Safari." Lets hope that like Chrome and Firefox, that extensions take off for Safari.
Do you know of similar Safari Extension resources that are either available or in development? If so, mention them below in the comments.
Keep in mind that while extensions will be useful, they may also be another source for odd problems either with Web page behavior, or with Safari itself. Along with troubleshooting plug-ins, extensions will also need to be considered if a problem arises either with specific Web pages or with future updates to Safari itself.
