Alt-text makes the web better for everyone, providing a window onto the world otherwise denied to people with vision deficiencies, and enriching the experience for people who can see the image but perhaps lack context.
The point of this extension is to surface alt-text for everyone.
The problem is that alt-text information is currently only surfaced when consuming Twitter through a screen-reader. As a sighted person, it's difficult to tell what alt-text an image has (though an image with alt-text is decorated with an [ALT] overlay, one cannot simply view the alt-text) and not always immediately obvious when an image is missing alt-text, for those who would like help in making the web more inclusive.
This extension is a little experimental, but works. YMMV.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
