Zooming with Mousewheel not working in Firefox/Produces Reference Error

Hi I’m using firefox on a Mac, and the mousewheel zoom function does not seem to work at all for me.
Occasionally it generates this error message when I try to scroll. Works fine on chrome.

thats really strange, i am developing cables a lot in firefox these days, don’t have this problem.

can you try to clear your cache ? or do you have a special version of firefox ? maybe can you make a screenshot of the console output ? cmd+alt+i and then “console”

thank you!
