How can I browse or query live MongoDB data?

Question

I\'ve googled around but couldn\'t find a working MongoDB viewer or data browser.

An ideal (for my needs) tool would be a web based viewer with dead simple features

Answer 1

"RoboMongo" is easy to use and cross platform, using on centos 6.2 but no option for data import/export which can be found in "umongo" but not easy to use as RoboMongo.
