Amazing! It's just that I can't seem to get the skip backwards and forward to function both in Firefox (nor Chrome). Maybe there's something I'm doing wrong, or dev can please look in to it. Cheers :D

I was impressed!! Sometimes you have to highlight the text you want to read before turning it on, depends on the website, but the keys are customizable and everything has been working for me without any fuss.
