hi I was able to make a bookmarklet to remove repeating emojis

for example if translation is
☺️☺️☺️[ smiling face ][ smiling face ][ smiling face ]

it will become
☺️[ smiling face ]

javascript: (() => {
let elements = document.querySelectorAll(".emoji-to-english-translation");
for(let element of elements) {
let text = element.textContent;
let words = text.split(/[\[\]]+/);
let unique = [];
for(let word of words) {
word = word.trim();
if(word && !unique.includes(word)) {
unique.push(word);
}
}
if(unique.length > 0) {
let newText = "[ " + unique.join(" ] [ ") + " ] ";
element.textContent = newText;
} else {
element.textContent = "";
}
}
let elements2 = document.querySelectorAll(".emoji-to-english-translatable");
for(let element of elements2) {
let text = element.textContent;
let newText = text.replace(/(\p{Emoji})\1+/gu, '$1');
element.textContent = newText;
}
})()


I tested the bookmarklet and it works.

I wonder if you can add this to the code, I'm not a programmer, I just asked bing A.I. to write the bookmarklet so I don't know how to implement it with firefox extension

After reading a site with a ... strange emoji that I didn't really understand I commented that it would be nice if browser would just add a tooltip with the emoji name.

Well, someone else linked to this extension that does this job perfectly. Thanks for building it!

Helps very much to decode vague emoticons !

Very useful addon, exactly what I was looking for, didn't see any alternatives either so thanks for creating it.

One minor issue: I use the addon in text only mousehover only mode and usually it works just fine but in some cases no tooltip appears, maybe the emoticon is obstructed by other elements z-axis/rendering-wise?

Works: direct url to a tweet
Doesnt work: tweets in tweetdeck
Doesnt work: comments on youtube, example: https://www.youtube.com/watch?v=OyXohnrEXVA&lc=z12ewxnzyoe0fpdpg04cibagpljvyb0b04o

edit: Thanks for the update, dynamic/delayed content loading makes sense and probably applied to all cases I ran into, I understand the performance impact of monitoring all changes, rescan seems like a good trade off for now.
Concerning twitter I suspect I was fooled by their own mouseover and the fact that you do seem to get the unicode when copy pasting. Anyway, if they use images that's their problem, unless many sites do something similarly addressed I wouldn't bother.

Sometimes I can't make out what an emoji does. This solves the problem easy and without fuss. That's it. It's glorious!
Today I discovered that there are options; now I don't have to spoil the presentation of the text.
