Instant Emoji Reaction is a tiny Firefox toolbar for dropping emotions on a page. Emojery is a shared reaction counter with accounts and public code.
Instant Emoji Reaction's Firefox Add-ons card describes a small emoji toolbar for reacting instantly on any webpage. The same card lists version 1.0, an 8.45 KB package, and a March 26, 2025 last update. It describes no shared count, no identity model, and no source repository.
So the 2 extensions answer different questions. Theirs: can I drop an emoji on this page? Ours: what did everyone else pick on this exact post, repo, video, or product, and can that number be trusted?

| Identity model | One provider sign-in for submissions | Not documented on the public Firefox listing |
| Source code | Public on GitHub, GPL-3 | All Rights Reserved; no public source linked from the listing |
| Package size | Larger: a picker, per-site adapters, history, and offline queue | 8.45 KB per the Firefox listing |
Instant Emoji Reaction's public listing describes the act of reacting on a webpage, but does not describe shared counts, identity, deletion, source code, or an audit model. If the reaction is not shared and counted, it is a very different product.
Emojery is built around the shared count. Every supported target can show a breakdown, and every submitted reaction is tied to one provider-backed account.
Instant Emoji Reaction is listed as All Rights Reserved and does not link a public repository. Emojery is GPL-3 and its extension code can be read, built, and audited.
A generic toolbar can be available everywhere, but it may not know what object on a busy page the user is reacting to. Emojery uses site adapters so the reaction is tied to the specific post, repo, video, product, or other supported target.
If the appeal is a few kilobytes of Firefox toolbar that works on literally any URL, Instant Emoji Reaction is the smaller and simpler thing, and Emojery will never match it on install size or on breadth of pages.
If what you want back is a number, that changes the requirements: a shared target, an account model behind each vote, and code you can read. That is the side Emojery is built on.
