Update: As of 2300UTC last night the plugin will no longer work on Twitter.
Tweet up to 280 characters using the new Twitter cramming feature, which otherwise is only available to limited users.
Short and Sweet.js is an accessible character counter for input elements. Tested on modern browsers with VoiceOver (Safari 11) & NVDA (Firefox 60).
Twitter released 280-character tweeting, but only to a few people during a trial period. This Chrome extension did add the ability for everyone to tweet in 280 characters on TweetDeck.
Update Oct 5: This extension no longer works. Twitter and TweetDeck are now both validating tweet length at the API. ⚰️
280 character Tweets are long and bloated. A lot of people hate them. If that's you, now you can block those Tweets from your timeline.
Block 280 will automatically collapse any Tweets over 140 characters for you. And if you really feel up for a good read, you can always click to individually reopen them.
