MS Caption Crawler
by Qihan, 2022-10-12

I don't like that if a web author has used a null alt (alt=""), this extension adds information anyway. A null alt is not a missing alt. It should leave these alone and only act when there is a missing alt attribute. Great tool though.

I like this Extension and I guess this will be helpful to developers who design the Webpages on the go and can run this extension to see the errors and fix them accordingly before deploying to the production. I like the feature that even if the developer fails to provide an alt it looks for the same image in other webpages and provides the alt to the screen reader user.
