Bryan Myers (ID: 000000b880d61383) Voted 1 ★ - Updated 08/20/2018 As a sighted web developer I couldn't get this to do anything when it was enabled. If I were blind it would be impossible to activate... even if that did anything.

Bradley Johnson (ID: 00000011763576ce) Voted 1 ★ - Updated 06/06/2018 no instructions!

Daubney Thielking (ID: 000000c881ae347c) Voted 1 ★ - Updated 11/29/2017 There's no instructions. I can't figure out how to work it.

Daniel Beaudoin (SK8ZION) (ID: 000000d7cb5f020c) Voted 3 ★ - Updated 08/30/2017 I can't vote this one way or another. There isn't enough information in the description to tell how to use it. The element it says to enable in Chrome://flags isn't there. And there is no intuitive way to figure out how to get it to read anything. Too bad. This kind of extension could be useful. :(
