Hi! I've just updated the extension, and I included some changes based on your review.

In FireFox, opening the file import selector will close the extension's popup, so the emote menu was simply ported to it's own page. It is now fitted better to the screen, and the "See all" section is now taller with 150% image size for better visibility (any bigger means blurrier, because emotes are usually very small).

This was a fast change; I'll be resizing the section's height to fit any screen vertically later. Thank you for the feedback!
