EDIT: Issues now enabled on Github. I looked into the current API for webextension on FF, and the API for opening the Downloads window/bookmark panel. Sorry

Hi there,
there's no need to wait for FF57, this will become compatibile with earlier version of FF (47-*) with the new version of the addon. It's already submmitted and awaiting review from AMO.

Bookmarks window and Downloads window is not currently supported. Feel free to submit a PR or open an issue on github: https://github.com/pmalecka/chrome-shortkeys

Currently the following actions are supported:
- Run custom JS
- Do nothing (for disabling a Chrome shortcut you don't like)
- Open a bookmark or bookmarklet
- Scroll up/down/left/right by a little or a lot
- Scroll to the top or bottom of the page
- Go back or forward in history
- Jump to existing tab by URL
- Open new tab with URL
- Switch to the previous/next/first/last tab
- Create a new tab or close the current tab
- Clone the current tab
- Close all (unpinned) tabs except for current tab
- Reload the page
- Copy the current URL
- Pin/Unpin the current tab
- Move the current tab left or right
- Zoom in/out/reset
- Blacklist or whitelist specific shortcuts on specific sites
- Clear downloads (page and bar)
- Click button and switch to next tab (for Tribal Wars players)
