Palfinger website will not load properly

[graywellparts]

We are a dealer for Palfinger cranes, and other products. A few months ago they updated the website, and now Palemoon will login but displays a blank screen. When I login using Firefox I see in the URL area a sub-page of /callback and a series of numbers flash by within 1 to 2 seconds. After that it shows that I am in dashboard that allows me to access all areas of the website. I am presently running version 28.13.0. I have tried going back to version 25, but have the same result.
Now Firefox works ok, but I much prefer Palemoon with it's support of plugins it displays pdf pages much better. Is there anything you can suggest?

The site works for me

[graywellparts]

That is the public access site. I am a dealer and login to a site that gives me access to look up parts, view technical specs, and so on.

If the problem occurs only when logged in, it will be difficult for people here to see what is going on.

Do you use some particular extension?
Maybe test the log in using a temporary new empty profile.

[Moonchild]

When you visit the site, press F12 to bring up the web developer tools before you confirm your log in, go to the "console" tab, and press the little trashcan icon to clear it (see screenshot). Then proceed with your login up to where you get the blank screen. Copy the output in the console (right-click->select all, then right-click->copy) and paste it in your reply, please.

The following is the information from console. Hope this will help.

[New Tobin Paradigm]

Have you heard of the code or hide tag?

[graywellparts]

I assume that the information I posted from the console was of no help. Would it be any help if I post the information from Firefox's console when I login?

[Moonchild]

Aside from there obviously being scripting errors on the site, it doesn't really tell us much if we can't access the code it refers to (then again, it's probably minified which would make it impossible to troubleshoot from the client side)
I doubt Firefox's console output will help, since we're not Firefox and it may use a completely different code path for it.
