I've been using this add-on since Firefox Quantum came out. My problem with it is that I have zoom levels set to increase in 10% increments and the add-on refuses to to respect that setting and keeps defaulting to this behavior eg.: 120%, 133%, 150%, 170%, 200%. What I have the zoom levels set to is: 120%, 130%, 140%, 150%, 160%, 170%, etc.
How can I get this add-on to go up or down in 10% increments?
