Mahjong Soul Ext. (All srv.) 作者： AT950

This is an edited version of the extension by K-izumi 様
https://addons.mozilla.org/en-US/firefox/addon/mahjong-soul-extension/

I added urls to the manifest.js to allow the extension to work on the English and Chinese server of Mahjong Souls (https://mahjongsoul.game.yo-star.com/and game.maj-soul.com).

If K-izumi 様 would edit that in him/herself, I would gladly remove this extension.

Translated description from the original page:
While playing Mahjong Soul, you can do the following with this extension.

Save screenshot with [Ctrl] + [S] (may not work properly with hardware acceleration enabled)
Discard the tile from the hand tile with the [1]-[9] [0] [-] [^] [\] [BS] keys.
Use the [q] [w] [e] [r] keys to turn on / off automatic tiles, etc.
Use the [Esc] key to discard tsumogiri (discard drawn tile) / skip
Send stamp (emotes) with numeric keypad
Key config (you can rebind the controls of the extension by going to its option page)


Note: The above functions work even when the game is not in progress (pressing the keys out of a mahjong game will click. It will not click outside of Mahjong Soul website). Beware of unexpected clicks. The author of this extension and the right holder of Mahjong Soul are not responsible for the events caused by using this extension.

You can see other disclaimers from "How to use" displayed when you click this extension icon.
