At my company we have some restrictions and a strong firewall that has lots of protection. I do not know all of the rules and security policies that has been made.

I noticed some changes in the log in on this site recently, since than I am no longer able to log in to Super User, nor StackExchange. 

I only have a StackExchange account.

When trying to log in from StackExchange, the only options that appear are:  
`click here to sign up` and `enter your OpenID`.  

From the Super User login window, everything seems to appear but the `Login` buton is inactive (the other login options act the same - including the facebook and google login). I can press it, but nothing happens. 

My question is:  
How can I troubleshoot this and get a workaround?

Note: I have local administrator account but I do not have access to the domain. I am using internet-explorer. Also I would prefer fixing the problem myself (if possible) instead of contacting the department who made the security policy.

EDIT:  
As I was suggested that my previous edit was offensive, I try to compose it in other words,  
I posted this question to the SuperUser section because I was expecting solutions Q&A style, corresponding to the rules of SuperUser.  

I still think that it belongs there but since 5 people voted so, it was migrated to meta. According to the rules of [meta][1], this post became a discussion instead of what I wanted it to become.  

However it is being treated unlike a discussion and even some partial solutions have been found.

I still disagree with the migration and I suggest replacing it to its original location as it corresponds to the rules of SuperUser and has nothing to do with the meta.
