Really good! I like it better than similar extensions since you can choose how many words show up at once. Almost everything is customizable.

My only complaint is you can't change the hotkeys, and there's no on-screen way to go back or forward words. The arrow keys are sometimes used by the websites I'm on, so that can get annoying.
Other than that though it's amazing!

It would be nice to be able to trigger it with right-click, but otherwise, it's great!

It works very well! Note, if you want to use it to read locally downloaded PDFs, you can't just open them in firefox and use this extension. There is a work around, https://mozilla.github.io/pdf.js/web/viewer.html. This link is the web version of that same PDF viewer, so the extension actually works. It defaults to some demo file, but if you to open your own file at this link, there is a button in the top right right corner near the end of the black tool bar.

One feature that would be nice is if there was a way to trigger it either from the right click menu or a keyboard shortcut because having to mouse over to the tool bar every time is just the tiniest bit tedious on my laptop track-pad.

Thanks for the great, free tool!

Very helpful and visually pleasant. Could use an option to increase number of words shown at a time (clustering).

I really like this extension. I was looking for an extension like SwiftRead but it's only available for Google. This extension is as closest as it gets.
> Same vibes and looks as SwiftRead
> Serves its purpose as a speed reader
> The dark theme and highlighted letters really asists my eyes in the reading process

It doesn't have much customazion/options that you can tweak around to your liking, but it's perfect if you just want a speed reading extension.
