Add-on summary
It's often difficult or cumbersome to tell if images have alternative text on Twitter. Alternative (or alt) text is used to describe images for those who can't see the image, making them more accessible.
This extension shows which images are missing alternative text, and displays the alt text below the images when available.
The extension also warns users when images in a tweet have no alt text when tweeting, and you can choose to disable the button entirely when alt text is missing, requiring you to add descriptions before you can tweet.
Version 1.6 includes permissions for the x.com domain, because that might be used.
Version 1.5 includes some extra options and fixes, Tweetdeck support has been dropped.
Version 1.3 introduces options to check the text of tweets for potential accessibility issues, giving suggestion on how to avoid those issues.
Version 1.1 introduces an option to hide tweets from accounts using an NFT profile pic.
