Issue with buttons on Firefox

Hello all,

I am facing a problem related to buttons only when the application is launched with the Firefox browser.

I have an ALV that has a button in 1 of it's column. That button has an icon and some text.

When I run my application on development, everything works fine on all browsers, that is the buttons are displayed with icons and everything.

But when the development was moved to another system, the buttons are not displayed on Firefox and Google Chrome. It works fine on IE9.

Both the systems have the same versions and there is no change.

Can you please suggest what could be the reason or where should I look related to the issue?

Thanks,

Meep.
