Thank you for this alternative. But would've been better if there was an option to enable the extension in every website instead of having to manually activate it.
And not sure if its just me but the 'listen' option isn't working for many words.

Some people are too impatient and want it to work without reading the manual.
2 of the 4 lines of the 'instructions manual' say:
"Just toggle-on for the tab you want and double-click / select the word and you're good to go."
Initially it didn't work (for me). I saw the new icon, played with it, and realized it had to be 'toggled-on' for it to work.
It works as in the photos. Sound too.
I was curious to see how it looks on a dark page. It looks the same. A few pixels of external-border-line would look better but not a big deal.
As with similar programs, it works on main-form words ( delay ), not variations (delaying). But if you just select [delay]ing , it will show up the definition with no-click-needed (what many people want, me included).
Thanks to the developer for giving us a working replacement for that other extension that stopped working.

I've just installed this, hoping for a replacement to another similar add-on that no longer works. Unfortunately, this add-on also does not work.
