Well, we can start here: www.apple.com/feedback/icloud.html
I just submitted a request there for a different iCloud problem (non-searchable emails on iCloud.com - I don't know if you have that problem too...)
I also just sent the below feedback for this problem too. The more the better, so please chime in...
"In Firefox 10 (and several earlier versions of FF), whenever I use the scroll wheel on the right-most preview pane at iCloud.com, emails scroll at about 25% of normal speed. This is not a problem in IE9... very peculiar. Will this get fixed?"
Glad I'm not the only one. For now I will have to have 2 web browsers open, sigh!
- IE 10: Running iCloud
- Firefox: Running the rest of my life
I just submitted the following feedback w/ Apple. Thanks all!
"In Firefox 20.0.1, whenever I use the scroll wheel on the right-most preview pane at iCloud.com, emails scroll at about 25% of normal speed. This is not a problem in IE10.
Will this get fixed soon? Please help!"
Good luck with that! I just submitted feedback with Apple as well. It is now almost April 2014, almost a year later and two years from the original post. You can buy Apple Care, but Apple doesn't care! No responses, no fixes...nothing. I left Google for iCloud, but now I have to deal with stupid issues like subscribed calendars in iCloud don't show in iCloud Web Calendar and ridiculously slow scrolling in iCloud web mail! Seriously?! We are not asking for the holy grail, just make some simple fixes!
