I'm glad to announce that, thanks to the fast work of the developers of F123 Access, Firefox users can now take advantage of several improvements to Reddit's accessibility. I emailed them yesterday, and the new features went public today. The enhancements the extension makes are:
1. The vote button is relabelled after you vote on a submission or comment. No more forgetting if you upvoted something already or not! Users of a screen-reader can now tell if one of the vote buttons was pressed, the same way sighted users can.
2. Comments are placed into nested lists. This way, screen-readers can now finally tell if a comment is a reply to the previous comment or not! This is a huge help when navigating through long comment threads, making it both easier to skip uninteresting replies, and much easier to follow the conversation.
You can get more information, and download the addon, at: http://f123access.com/
As well as making accessibility improvements to Reddit, F123 Access can also make improvements to Facebook, Youtube, WhatsApp, and many other websites. Just choose the enhancements you'd like to enable in the F123 Access preferences once it's installed.
