This has a lot of great features for a speed reader. I'm surprised the store doesn't have an icon. This appears to be the best Speed reader extension for Firefox.

I've tested a few alternatives for RSVP (Rapid Serial Visual Presentation)
This is best one, by far!

Наконец-то обнаружил reedy в Mozilla. Мега полезное расширение, без него большие тексты даже читать не хочется.

I missed a lot this extension on Firefox, thank a lot for the port of the extension of Firefox.

I was first introduced to RSVP reading as a schoolboy in the early 70s. It seemed like a novelty then, and quickly forgotten. Then at the dawn of the PC age some new software appeared (called Mars and/or Tenax, if I recall correctly) that allowed for it but was very clunky. Then a spate of better readers appeared, still clunky. Finally Reedy showed up and it was almost perfect. I first installed the Chrome browser for the sole purpose of using Reedy. Now we have the FF port - thank you!! This really has improved my life, especially my work life, where I have to read a great deal online. The only thing I would ask for is for it to function in FF reader mode (as another user has pointed out). Oh, that and I would also really like to see an option where it takes a pause (of user-specified duration) at the end of a sentence and/or paragraph. Thanks again.

Прекрасное дополнение. Позволяет значительно увеличить скорость чтения, благодаря особой методике отображения текста.
Настроек достаточно, дополнение работает юез сбоев.
Разработчику огромное спасибо!

One of the only reasons I had Google Chrome installed was for this addon. Now that there is a Firefox port of it, I can finally seamlessly integrate it into my standard workflow. If only PDF files could work seamlessly with the extension- although I know that's quite a technical challenge in its own right which no speed reader I know of has tackled elegantly.

I highly recommend everybody has this plugin installed. Someday, I hope it works on the Firefox Reader View (F9) as well, but for now switching to reader view and copy-pasting the text works well enough. I'm tremendously grateful for any good Firefox speed reading solution as it is, so my ecstasy will persist nevertheless.

The long-awaited appearance!
I have been using Reedy for several years and really lacked this for FF. It is very convenient when you need to quickly read a long and boring text).
But how to turn off word wraps? This is convenient in "traditional" reading, but poor in high-speed, word-for-word reading.

I've been waiting for a Firefox add-on of Reedy! Excellent speed-reader with a lot of customisation possible. Great job!

Thank you for this port. It deserves much more attention. Reedy is by far my favorite RSVP reader. I still have Reedy Pro (which is no longer available ) on my old Nexus.

I found this app on Chrome and since switching across to FireFox I had missed it, thank you for the port it works great!
