Firefox doesn't work on certain websites

Question

I am continually running into sites that don't work well with Firefox. I tend to think it's because of the rapid-fire changes FF makes to itself, but nevertheless, it's annoying. The sites all tell me to "use Chrome" as a solution, and most times, that works. The thing is, I don't like Chrome. I have FF set up the way I want it. It is my browser of choice, despite the fact that it is losing users to Chrome every day. I don't think I will ever switch, but I really need it to work consistently. I'm having to use the portable version now because the desktop version doesn't work for me anymore. After the latest update, Flash sites won't load half the time. They too work in Chrome.
This time it is redgage.com. Most of the features only work if I use the right click and open it in a new tab. I've tried safe mode.
What is the solution to this? I don't have time to keep making adjustments to the program and coming in here to get no answers, and everyone saying they have no problems. SERIOUSLY? That's not what all my friends who switched to Chrome are saying. I feel like I'm losing my right arm.

Answer 1

Yes, every link on RedGage is broken. To open one in the same tab, you have to drag and drop it on the address bar.
But I think it's their fault. In the Browser Console:
13:46:52.262 ReferenceError: event is not defined MainViewModel.js
Looks like a rookie mistake in this script:
self.trigger = function (modelView, evt) {
var target;
util.hidePopup();
'''if (event.ctrlKey || event.metaKey || event.which == 2) {'''
return true;
if (evt.preventDefault) {
evt.preventDefault();
target = $(evt.target);
} else
target = $(evt);
var url = target && $(target).closest('a').attr('href') || $('.filter li.active a').attr('href');
if (url)
self.do_load_url(url);
return false;
In the bolded line, "event" is a typo and should be "evt". Maybe if you point them to this thread they'll fix it. Even if other browsers work this way.
