Hide images previews, promoted content from Twitter timeline. Can also hide «Who To Follow» and «Trends» modules.
Late October 2013 Twitter added a feature that automatically expand image or video preview in tweets that contains media.
Some find this quite annoying. This extension simply hides auto-expanded images and video preview from your timeline while still allowing you to expand tweets by your own.
v1.4 - (2015-07-05) Now hides autorun videos.
