Having issues in my game

I am developing a HTML5 game, I need to make it work on pc browser, android and ios browser, I having the following problem

1. Sound is not playing in IOS mobile

2. New Tabs are not opening in Safari (am using browser "open url in new window")

3. Objects behavior are not working properly in FireFox Android

4. In android mobiles, in landscape mode, when keyboard popsup to enter value in textbox, the layout becomes so small that we cant see the text And in IOS, the textbox is covered by keyboard so we cant see the text inside the textBox

Please Help me with these issues

1. Read about IOS limitations here:

If you are using C2, make sure all sounds are in .m4a and .ogg formats.

If you have very short sounds (less than 0.1s), this can also be the reason why audio doesn't work on IOS. Make sure all sounds are longer than 0.1s

4. The proper solution would be making your own keyboard. See this tutorial:

Hi dop2000, Thanks for your reply

I am using .ogg audio format. In IOS browser the music is not playing after my first touch also. And also sounds are longer than 0.01

You also need your audio in .m4a format for iOS, because it doesn't support .ogg. It's all described in the manual.
