Installing Chrome extensions when --user-agent flag is overridden

At work I'm behind a proxy that kills traffic from Google Chrome, by detecting the User-Agent. I can get around this by overriding the --user-agent option and setting it to Safari. The problem is that I now cannot install any Chrome extensions because Google's website specifically looks for "Chrome" in the User-Agent variable. Does anyone know of a way to ge开发者_运维问答t around this, and trick google into installing a Chrome extension?

EDIT : I tried setting U-A to "Chromium" already and that is also blocked.

All you need is figure out URL to an extension, then you can just download it in any browser and drag the file over Chrome window to install it. Extension URL has the following format:

https://clients2.google.com/service/update2/crx?response=redirect&x=id%3D<EXTENSION_ID>%26uc%26lang%3Den-US&prod=chrome&prodversion=11.0.696.16

If you go to extension gallery in any browser you can get extension id from the url:

/detail/<EXTENSION_ID>

Try setting your user-agent to "Chromium"?
