What if your slack emoji came with you on any webpage you went to? What if you could type :buttbrowdotpng: in your github commit and see 
The slack emoji anywhere extension finds slack-formatted emoji (e.g. :hi:) in any browser text and replaces that string with the image of the :hi: emoji from your slack instance.
To aid in this, the extension gives helpful shortcuts to grab a slack user token, update the extension's emoji cache, and open the emoji customization page for your signed-in slack instance.
The extension also allows you to search for and insert emoji using the chrome omnibar. Just type cmd+l to focus on the bar, then :, tab and you'll be able to search existing emoji. When you find what you're looking for, press enter to copy it to your clipboard and enter it under your cursor. You can paste them in either as the direct url, a markdown link to the url, a markdown image (works great on github PRs), or html image.
Well, you're stealing your cookies. It's a serious and legitimate security risk, and using this extension probably makes your slack interactions less secure. I comfort myself with the fact that Slack operated without cookie based authentication for 8 years (until roughly July 2021), so for the 3 years or so that emojme and that somewhat lacking auth scheme were coexisting, you were equally if not more unsafe.
At time of writing, the slack emoji anywhere extension is only available unpacked, not through the chrome web store. There are all kinds of guides to get that done, but the short version is to download or clone this repository, open chrome://extensions, turn on Developer Mode, and click Load Unpacked in the upper right. Have fun! :goatbutt:
