Purpose
I need standard zooming functionality to work properly on Firefox 60.3 ESR.
Problem description
I run Firefox 60.3 ESR. Preferences are default, about:config is default. No extensions in the browser, neither meta-extensions in Debian.
I open a website. I use touchpad to access the "hamburger" menu in Firefox and single click zoom in. Zoom in goes straight to 67% from 100%. When I click zoom out, zoom level goes to 80%, but not higher.
Questions
Is this a bug? How do I restore proper zoom functionality, e.g. zooming down in single steps and zooming out to a 100+% ? What is the method/approach how to proceed to find the cause of this problem?
You can install the newest release of Firefox, and test if the problem persists. You can install an older version and see, if the problem is a regression. – davidbaumann – 2018-11-13T11:12:48.977
