[Bug] When using padloc.app, typing a letter associated to a Memex keyboard shortcut calls the sidebar

[albertocottica]

If reporting a bug:

1. Can you describe the problem and bug in more detail?
   I use padloc.app with Firefox 71.0 (64-bit) on MacOS 10.14.5 (18F132). When typing the passphrase, typing any key that Memex uses as a keyboard shortcuts results in the sidebar appearing, and the input from the keyboard being shunted over to Memex. Quite annoying, when you are trying to type a passphrase!

2. How can we replicate the issue?

Create a free account in padlock.app and type in their input field (like "email address" or "passphrase") letters associated to a Memex keyboard shortcut. For me it's h and c, for example.

3. Expected behavior (i.e. solution)
   Typing your passphrase undisturbed. Memex does not appear unless summoned.

4. Error stack (from extension crash page)
   This issue does not lead to a crash.
