If you are a web developer you must be familiar with the bootstrap although it was a excellent framework it come with a number of problems one of them is the dropdown problem in Firefox browser. Firefox is a browser that most people are in love with for its unique qualities, so as we cannot leave it that easy.

Input view in Firefox browser

Input view in other browsers
So we have to come up with a solution for this, there is no way to change the browser behavior but we can replace the forms with other simple input templates.
Bootstrap Select & Select2 are the replacement for the input forms and unlike the default input box they don’t have the problem of looking differently in various browsers.
