Fix compatibility IE and FireFox(repost)

One html page works ok in IE but NOT in FireFox. Most likely, the JavaScript code is specific to IE or there is a bug in FireFox - or a JavaScript library used. The problem is very simple: we can't set focus on some by click with the mouse. In attachment, you will find a HTML file with dependent css and js files (this was created with Firefox). That page has several "input" fields. Using Firefox, it's impossible to set focus on the 2 following fields: "Description" and "Ref. fournisseurs" Other fields are Ok. If you are using IE, focus can be set on all the fields. Thanks for your attention. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
