Hi, thanks for using Steemoji.

Sometimes the Firefox cache can lead to it, that at the first use, the Steemoji menu is not recognized. We use a content script and Firefox caches content.

In matters of the permissions, we use the following permissions:

contextMenus -> Because of Emoji Button
activeTab -> Because of background script, so we can react to the contextMenu
tabs -> Because of background script, so we can react to the contextMenu
storage -> I want to develop a "mostly used Emoji - Tab"

I hope it clears a little bit.
