At the moment, Firefox does not have a feature to assign keyboard shortcuts to extension features. The extension can assign one or more keyboard shortcuts to itself. I posted an issue for the developer to consider here:

https://github.com/itseco/to-google-translate/issues/6

1. I want to change shortcut or create new shortcut for all add-ons. 2. which can perform same work on firefox menu.

         has any add-on which can full-fill all requirements?

> 1. I want to change shortcut or create new shortcut for all add-ons.

I have not heard of any feature/extension for that.

> 2. which can perform same work on firefox menu.

Over the years there have been extensions like keyconfig and menu editor, but I don't know whether they still work.

"Dorando keyconfig" add-on can not create new shortcut for Print preview option.

OK, it is now up to you to figure things out here. as per Contributors last post. This is a Developer Issue, ask here https://developer.mozilla.org/en-US/

We do not have a answer for you. Firefox Ver 55 to be released on Aug 8th

So what we do here may not even matter once you have update as things may have changed. Come back after the next release.

Maybe try this one if that is the specific one you need a keyboard shortcut for: Print preview button (restartless) (adds Ctrl+Alt+Shift+p)

Print preview button (restartless) has a shortcut. But I can not change it.

I also need changeable shortcut option for To Google Translate add-on.
