Comment 146 for bug 66566

Jesse, you can follow the progress of the issue/bug for better keyboard shortcut control here https://bugzilla.mozilla.org/show_bug.cgi?id=1215061
When it's done there can be extensions that change this behavior. It is a bit unfortunate the change to webextensions was rushed and now we are missing some features.

:Gijs, I don't know how to tag people here so I hope posting here again is ok to contact you. Could you show me the lines where you changed this code so I can have a look at it? Because on the issue I created it was said that it might be too much development effort to fix the issue (resolving the inconsistency of pressing multiple modifiers and enter in the navbar). Thank you!
