i found a thread that shows the scrollwheel code line that needs to be set to false for stopping the annoying scrollwheel zoom. but I can't post on that page because i don't have a 10 reputation and apparently it drew some kind of spam . . . so sorry for redundancy.
my problem is i don't know where to find this code or how to open it and change it. It seems this might be browser dependent but i'm unclear on that. i'm running Firefox 47 on a Mac Air System 10.10.5
it drives me absolutely crazy that google wouldn't just provide a toogle for this feature which takes over a standard function of the operating system, esp. since 99% of the time you can's scroll by using the arrow keys without standing on your head and whistling the star spangled banner backwards so not only is the instinctive speed of sound zooming absurd but i have no way to scroll the display without the carpel tunnel inducing click-hold-move cursor
i have no clue what made them think zooming was more important than scrolling. i suppose the only advantage is i might learn something low level about coding to these interfaces.
thanks if anyone can walk me through this step by step.
