Twitter Sidebar ਵਲੋਂ Theo Osborn

This extension adds a new section to the Firefox sidebar which contains the Twitter mobile web app. It can also contain Tweetdeck, which is enabled in the Add-on options page.

Press Shift+Alt+U to open. This shortcut can be changed by going to Add-ons -> Twitter Sidebar -> Options.

This is an unofficial addon and is completely unaffiliated with Twitter.
