In Firefox, there is a strange blue border that appears when selecting multiple rows by pressing the ctrl button. However, this issue does not occur in Chrome.
This behavior was observed using the latest Firefox version 10.0.2.
Do you think this might be a browser-specific bug?
The reason for this behavior is due to the browser's native action of text selection.
You may encounter a similar issue in Chrome when using the SHIFT key instead of CTRL.
To resolve this, you can clear the selection immediately after the user clicks on the cell:
$(".subject").on('click',function(event) {
if(event.ctrlKey) {
$(this).toggleClass('selected');
} else {
$(".subject").removeClass("selected");
$(this).addClass("selected");
}
if (document.selection)
document.selection.empty();
else if (window.getSelection)
window.getSelection().removeAllRanges();
});
To prevent default selection behavior, you can try adding the CSS property -moz-user-select to the table element:
table { -moz-user-select: none; }
If you're using the latest version of Firefox 20.0.1, you can make text selectable in cells by adding an extra element inside.
td { -moz-user-select: -moz-none }
td * { -moz-user-select: text }
