Twitterぼかし is a Chrome add-on developed by negi_0919 that aims to combat harassment and inappropriate content on Twitter. With the recent trend of replying to tweets with explicit images, this add-on provides a solution by blurring all images in tweets and replies. Additionally, it also blurs the user's profile picture and other images associated with the tweet. Users can simply hover over the blurred image to reveal the original content.

For those who want to extend the blurring functionality to include videos in tweets and images/videos sent via direct messages, the add-on "Twitterぼかし+" is available. This add-on not only supports blurring images and videos in tweets but also extends the functionality to direct messages.

Twitterぼかし was first released on January 21, 2018, and has since undergone updates to enhance its features. Versionintroduced changes to the blurring of images and videos in direct messages, requiring the use of the "Twitterぼかし+" add-on. The add-on's name was also changed to "Twitterぼかし" to reflect these updates.
