Okay fine, I'll write a review. 🙄 So, there are several of these emoji add-ons available on here, and to be honest, you really only have two to pick from. This one "Emoji" (or emoji-sav) 👍🏼 which is also the only one, that has a Firefox recommended Add-on Badge. 👍🏼 That means that it's the only one that meets Firefox's standard for security and performance. 👍🏼 The other one (add-on), that I was using, seem to be slowing down my browser. So, for the past 9 months I've been using "Emoji" (or emoji-sav).

The "Emoji" (or emoji-sav) is the better add-on, out of all of them overall, for several reasons. One, being its versatility of its settings, and the other (for me) is that it doesn't slow down my browser, like the other I was using did.

Now, 🤔 I do have one issue, and that's, that it is missing (as of this date Oct, 2023) some of the standard emoji's. For example; the ✨ (sparkles), is missing. There are others that are also missing, but I am not about to list them all. So, that's it, that's my review.

UPDATE:

In response to the developer; As I come across them, I'll take note, and contact you via, email or GitHub.
