Hello UgoChaves,

This is what I found (among other, similar things) :

https://www.reddit.com/r/firefox/comments/7yd3t5/disable_ctrlw_closing_tab/

And :

http://shallowsky.com/blog/tech/web/firefox-quantum-fixing-ctrl-w.html

Doesn't put a smile on your face, does it  ?

Unless somebody else can come up with a perfect solution, I'm afraid that you will just have to be extra careful when you want to press Ctrl + E ......

Second link's article fits me, thank you

You just put a great big smile on my face  !

(thought you'd be disappointed .... )

Tell me more about what I could not understand. I came on forum because Shortkeys does not work on my Firefox (i dont know why). It was first what i tried.

If you have any other questions :

Just start a new thread and ask away  !

There are many contributors on this support forum who know way more than I do ......
