Hello, I will try my best to guess the issue you are reporting. I don't speak Mandarin and I used Google Translate to guess what the issue is. So, if I got that wrong, I do apologize.

You are looking to disable the Firefox shortcuts - all of them. And you want to do this because you think these shortcuts are blocking a Firefox plugin you are using. Is that correct?

您想禁用Firefox的快捷方式 - 所有这些。并且要做到这一点，因为你觉得这些快捷方式阻止你使用的是Firefox插件。这是否正确？

谢谢

It's not because these shortcuts are blocking a Firefox plugin i am using，but these shortcuts caused problem When I use other software。They have the same shortcut keys.

For example,I want to use “Ctrl+D” delete a line in other software，but it has no effect when firefox is open.so i want to stop these shortcut.

Thanks!

When a window with that other software has focus then that program should process the key presses and Firefox wouldn't have any effect on this.

Is this an independent program or are you running it in Firefox or opening a file in this program via a download (open with) action?
