Mac OS 10.6.8 iMac, running FireFox 15 in grade school computer lab. When Parental controls are enabled in system preferences Firefox does not work properly. Can't use Google to search from the search bar at the top, can't access plug ins, there are even a few websites that can't be used. An example is digitalpassport.org from Common Sense media. Students can't access to log into their accounts. Parental Controls have been running on these macs for over a year with no issues. I thought it was the latest Firefox version giving us a problem but I updated to Firefox 16 today and the problem persists. If I turn off parental controls, Firefox works perfectly. I was not previously limiting applications, just blocking youtube and facebook. I tried limiting applications and then allowing all of them but that didn't help. What am I missing? Also, I can't access Mozilla support pages either when Parental Controls are enabled.
