google brower chromium works well, but firefox does NOT! if i using ff with noscript, adblock plus plugin enabled, ff will report proxy search(since i am access google site to googling something) invalid.

google browser works well!

the url looks like this when using google searching something : https://xyzproxy.com/search?q=greate+firewall&gbv=1&sei=hgz0W-anGoLQwAKmkJv4CQ

and the screenshot of the search looks as the attached.

see attached

Stop using the proxy and see if the problem is still there.

Was about to say the very same thing.

Great minds think alike. Have you seen mine? I lost it somewhere.

at home to access google.com, i have to use proxy otherwise, it is blocked by china.

the obvious is google chromium DOES work well when using same proxy.

i have been using ff for long time. dont let me down.

Have you tried contacting support for your proxy? Or tried using another one?

I called for more help.

i think it ff issue, not proxy issue, otherwise google chromium will not work well either!~

This can be very problematic considering your location. Also along that line did you contact the Proxy support to ask them as well?

if google chromium works, why do you think proxy issue?

do you think it is google chromium does not follow the rules while FF follows which cause the problem? or is proxy service not compatible?

Google Chromium isn't part of the Mozilla software so they have no control what Google does.
