A manual call of coex_on(); or of coex_off(); in the web console of firefox did not yield any observable effect. Also, I tried to traverse the file system using window.location.assign("/"); with no success. Further suggestions, in particular suggestions about javascript injection via postHttpRequest(url,params_array, callback) are more than welcome.
Cheers,
