Recently I've realised that, some adblocker extensions (such as adBlocker plus) block some Ajax calls. I get that error on the console:
GET http://localhost/prj/conn.php?q=users/list/ net::ERR_BLOCKED_BY_CLIENT
Why does it block some Ajax call but not the others and what causes that? Is there any workaround other than telling user to turn off adblocker? Any help would be appreciated, thanks in advance...
