Firefox: right click menu in Quire APP call firefox context menu, not menu of Quire Options

Firefox Latest stable version (62) but tested on all versions of FF, everywhere this bug. Need to hold right click (click right-click the button and hold button do not release the button) and only then you will see a menu of the Quire. It's not correct behavior.

How it must work:

• I click right click - and I see context menu of quire app, not firefox one
• like it exactly works in Chrome

P.S. thx for a fixed bug with service workers on firefox, now quire works fine in offline mode ()
