Google Chrome being blocked by company firewall

Yesterday I could use Google Chrome at work to access the internet and today it is being blocked by the firewall with an access denied error. IE and Firefox work fine from the same machine. Is there a way I can easily unblock Chrome so it works again?

The blocking is probably being done using the browsers user agent string. You can change the user agent string using the --user-agent command line argument to impersonate IE8, for example use the following.

"C:\Documents and Settings\\Local Settings\Application Data\Google\Chrome\chrome.exe" --user-agent="Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0)"

This of course assumes they are allowing IE8 :-)

However, even if this works, you should check your companies support policies as you may be breaching them.

A lot of places have a proxy server that you have to use to access the internet, if it's site in IE and Firefox but not Chrome, you'd not be able to get online. Check in Firefox's settings to make sure..
