I'd give it 5 stars but it doesn't allow you to use "ctrl+." as a keyboard shortcut, just "modifiers + alphanumerics", can you add this functionality? Because of this, right now I'm using another extension that allows me to do this, I bet it's a super small fix, thanks!

Edit: I did a bit of research, seems like you can add this behavior by mapping "," or "." on the extension settings to the words "Comma", and "Period" (as an example if you add this two characters), those are the words Firefox understand for the "key combinations".
I manually modified the settings that you can import (thanks for that funtionality!) and it allows me to use "ctrl+." but then I cannot access the configuration anymore (I bet it's because the extension reads the character "." for the shortcut and returns an error, as it is not an option on the list).

Edit 2: I was hoping that your extension was open sourced, what a joy to find that it was, I've been reading the source files and I think I've found a simple way for adding this functionality, I might be doing a pull request on these days :), hope it comes useful, thanks for your work!

Edit 3: I edited the popup.html file by adding a new option value for "Comma", but it seems the code is doing something extra since Firefox interprets the value as "Com + Comma" and it returns an error, I'll check on this later, I think I'll open an issue in the repository with this information since it escapes a rating commentary haha, thanks :)

Some are nice, many are nothing like the image we click on, many are ugly as hell, and too badly made to even tell what they are representing. Must be better ones out there.

It's easy to add emojis that you frequently use directly from Firefox without the need for external tools.

Thank very much!!

Works okay but isn't keyboard users oriented. The number of possible shortcuts is limited, you can set it e.g. to ctrl+shift and any letter or any digit but you cannot set it to something like ctrl+shift and a period or space or comma. After typing in your search phrase there's no option to copy the first one after pressing enter - you have to press enter twice because it assumes the users will more often use the arrow keys or mouse to select exact emoji from the grid than improve their search phrase. Those are minor issues but still, issues.

Very useful

Nice add with great potential.
