On my work computer, on the work network (not at home), FireFox can't get into gmail, nor see graphics on this site or ones like Linkedin. Settings to change?
Got a new computer at work that is very locked down. I am running Firefox off my USB since they give us only IE 8 and a very locked down Chrome that has no access to extensions,
At work (not at home), when I try to get into gmail, I get all these certificate errors. Granting exceptions doesn't work.
Another problem is when I go to sites like this one, or like Linkedin, it is all text, no graphics. But when I use this same computer on my home network, there is no problem.
Would appreciate if there is some setting I can change on this to enable access.

On your work computer, you're probably behind a proxy server. When you make exceptions and proceed to a site, often you will get an incomplete page load because many sites now use multiple servers and the exception only covers the main one.
Assuming that is the problem, you may be able to import whatever certificate IE and Chrome are using to get around this problem. (They both share the Windows certificate store.) In particular, there would be an master certificate that the proxy is using to sign its fake SSL certificates that you could export from IE and import into Firefox as an Authority. I assume this would work on a Portable version of Firefox, but I've never heard of anyone trying it.
Thanks for your reply. I went into IE and Viewed the Certificates and there are a ton of them: Trusted, Untrusted, Personal, Intermediate, Root. I did see four in the Roots one that had my company name + Root + CA. Should I export all 4? When I try to Export, PKCS and Microsoft are grayed out, only the DER, Base, and Cryptographic are available.

I think the DER format is the correct one for importing into Firefox's Certificate Manager tab:
"3-bar" menu button (or Tools menu) > Options > Advanced > Certificates mini-tab > "View Certificates" button > Authorities tab
However, you might want to search around a bit on this since I don't have any personal experience with such proxies.
So I've still had no luck. I've exported a lot of certifications, all as the p7 format, and imported into Firefox, but I'm still getting these errors. So frustrating I can't use it properly.
No, I'm pretty sure the p7 format isn't the right one for this. You want the DER format.
So in IE/Windows Certificates you're exporting from the Trusted Root Certification Authorities tab. And then in Firefox, make sure you're importing on the Authorities tab.
So even after exporting every single one, with many formats, I still couldn't get it to work. However, my employer finally relaxed restrictions on google chrome, so I won't need Firefox anymore. I guess it's ultra caution wouldn't let me get past my own employer's proxy servers, so I couldn't use it.
