What are your network settings in Options > Advanced > Network > Connection?

Thanks for looking into this issue.
Options > Advanced > Network > Connection is set to
Use System proxy settings.

Additional information,
Chrome and IE are working fine in this scenario.

I don't know if you use a proxy at work, but before leaving your work to go home, can you set these settings to "no proxy" and test at home.

Yes I use proxy at work. That means every time I have to change this settings when I come back to home from work or go to work. Can't this happen automatically like chrome?

Some more information,

I checked chrome settings and found that it by default uses system settings. Then I checked my LAN settings. It is set to the following;
Use Automatic configuration script and an web address is given.(e.g. http://xyz.name.com/)

I guess you will need to use a PAC file or a script to switch between both configurations:

But it's a thing that the IT guy of your corporate should manage if you use your work computer at home.

Thanks. I will try the PAC file option. But just curious, how chrome is able to handle it? I don't need to make any changes to chrome settings and it works absolutely fine.

Hi, would you please try Firefox Nightly and see if this issue has been fixed?
