MacOS - Pinch to zoom doesn't seem to work or be enabled by default in Firefox 57 Beta. This breaks basic MacOS functionality. Totally unacceptable. Fix this.

You can restore some zoom feature by modifying the values of the related prefs on the about:config page via the right-click context menu.

  • browser.gesture.pinch.in = cmd_fullZoomReduce
  • browser.gesture.pinch.in.shift = cmd_fullZoomReset
  • browser.gesture.pinch.out = cmd_fullZoomEnlarge
  • browser.gesture.pinch.out.shift = cmd_fullZoomReset
  • browser.gesture.pinch.latched = false
  • browser.gesture.pinch.threshold = 66

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.


Note that there is a Legacy extension for Firefox 56 and lower that modifies some prefs, but that no longer works in Firefox 57+.

Corel,

Users should never have to modify about:config to access basic functionality. This is an unacceptable QC issue as is your response, which enables developers to slack at their job.

Absolutely inexcusable.

It is a decision made years ago.
