Please be kindly to open this site http://clients.konfiga.com/ on both mozilla & chrome. You'll notice there's a slight difference on header & footer widgets (the search & subscribe form)
I really have no idea what causes that.
What you can do is set the width you need need it to be in firefox and other browsers like Internet Explorer, then just target chrome to edit the width of the input field using:
@media screen and (-webkit-min-device-pixel-ratio:0) {
/*Chrome CSS here*/
.input[type="search"]{
width: 231px !important;
}
}
/* For other browsers */
.input[type="search"]{
width: 210px;
}
So set the width of your input field to be 'width: 210px;'
Then use the @media screen code above to target chrome and set it to the width you want on there. A possibility?
