Tried to use some extensions and none of them helped. There is another reason why I need cookies normally tracking the sections I have already visited. Normally some sites I visit have settings like view only selected items and such if I have cookies enabled. But whenever I visit such sites I have to reconfigure my settings again. Before when I was using Maxthon another portable browser it allowed such settings to be saved and the browser records the cookies properly.
Take for example the site http://bato.to on the right side of the site there is a setting for "Currently displaying: Show All" Normally I set it to "Currently displaying: English" and my old browser Maxthon properly saves this setting in its cookies even if I restart the PC or move to another Net Cafe. But with Opera installation on USB it does'nt seem to work.
I do hope you guys will look into this matter. Really need to get the cookies working on USB install of Opera. Thanks.
