About a month ago a half dozen kids at my high school (CASHS) got computer priveliges limited because they were caught after installing Firefox

on the school computers...the principal mentioned it during an assembly:
but our tech staff is great they caught them right away...
Errr most of them had had it since the beginning of the year...about 9 months ago?
They should have given them cookies for installing Firefox and followed their example

Has your school IT staff done stupid stuff?
