Paridae is a Chrome extension developed by donnierayjones that aims to make twitter.com more adaptable to different screen sizes through responsive design. It used to be called "Responsive Twitter" but has since been renamed.

The most recent changes to the extension include better support for multi-photo tweets and style updates for the new profile layout on Twitter.

Paridae offers several features to enhance the user experience on twitter.com. It shrinks the website to fit in almost any width, ensuring that it is responsive on different devices. It also disables jQuery animations, making the site feel quicker.

Additionally, Paridae provides a browser icon/button that allows users to open twitter.com in a chrome-less window, without any toolbars. The extension remembers the window size and position upon closing.

Users can open links in the background and use the keyboard shortcut "o" to open links. When the window is small, Paridae removes hover effects and favors keyboard shortcuts over mouse interaction.

Furthermore, Paridae supports the omnibox (address bar) functionality. By typing "@" and hitting tab, users can search Twitter, go to a specific user using their username, and utilize single letter keyboard shortcuts for various actions.

For a detailed changelog, users can refer to the git history available on GitHub.
